Keratin method of application. How to use keratin for hair: the pros and cons of this procedure. Liquid keratin: ampoules for hair restoration. Highly concentrated keratin preparation DNC

In the article we discuss keratin for hair, tell you how it works, what are its advantages and disadvantages of keratin procedures. You will learn how to perform keratin hair straightening in a salon, and how to make a keratin mask at home.

Keratin is a highly durable, water-insoluble fibrillar protein that makes up the horny derivatives of the skin epidermis - nails, hair, and keratinized areas of human skin. The structure of keratin is:

• soft (alpha keratin);
• hard (beta-keratin).

Alpha keratin is involved in the structure of the horny derivatives of the human epidermis; more than 80% of hair fibers consist of it. The strength of keratin is reduced due to constant dyeing, perming and high-temperature drying and styling of hair. Hair loses its shine, becomes porous and brittle.

In 2006, in Brazil they figured out how to straighten naturally curly hair using keratin. Today, with the help of keratin, they not only straighten hair, but also perform restorative procedures for damaged curls. Most often, keratin is obtained from sheep's wool and added to hair products. It is considered to be more related to keratin, which is produced by the human body.

Advantages and disadvantages of the procedure

Like any cosmetic product, keratin has advantages and disadvantages.

Pros of keratin straightening:

• restores the natural structure of hair;

• increases hair strength and seals split ends;
• straightens hair and fixes the result for up to 4 months;
• gives hair shine, it becomes silky, easy to style;
• promotes long-term preservation of the color of dyed hair.

Disadvantages of the keratin procedure:

• products containing keratin may contain formaldehyde, which releases toxic fumes when heated;
• the procedure is not suitable for dry and thin hair;
• keratin makes hair heavier;
• high cost of the procedure in the salon;
• During pregnancy and lactation, you cannot undergo keratin procedures.

Keratin hair straightening

The procedure for straightening hair with keratin is as follows: keratin particles penetrate the hair and fill microcracks. Under the influence of a temperature of 230 degrees, the hair scales are sealed. Due to this, the keratin composition is retained inside the hair and serves as a kind of frame that keeps the hair strands straight.

Procedure options

The keratinization procedure is carried out using Brazilian and American technology. The American version of the procedure is considered safer because keratin preparations have a natural composition and do not contain formaldehyde. However, Brazilian hair straightening lasts longer and costs less than American hair straightening.

How the procedure is carried out in the salon

The procedure is most often carried out according to the standard program:

1. The hair is carefully combed with a fine-toothed comb.
2. Wash your hair with a special shampoo, which thoroughly removes all impurities and lifts the hair scales for better penetration of keratin.
3. A product containing keratin is applied to damp hair.
4. Hair is dried with a hairdryer without styling.
5. Divide the hair into strands, then straighten each of them with an iron at a temperature of 230 degrees.

Hair care after the procedure

1. Do not wash your hair in the first 3-4 days so that the keratin becomes firmly embedded in the hair structure.
2. Use special shampoos after the keratin procedure that do not contain sulfates and parabens.
3. Do not color your hair for 2 weeks after the procedure.

Reviews about the procedure

Below are several reviews of keratin hair straightening.

Anastasia, 28 years old

I did keratin once. After it, my hair became incredibly smooth and soft to the touch, I touched it constantly. The straightening lasted about a month and a half, then the hair gradually began to curl. The high price of the procedure and hair products scares me off.

Valeria, 31 years old

Hair after Brazilian straightening does not frizz or frizz, even in the rain. I recommend! Cons: terrible smell during the procedure and loss of hair volume.

Margarita, 38 years old

I straighten my hair with keratin every six months. I have already done 5 procedures. Previously, without keratin, my head looked like a dandelion after washing, and each time I had to work with the iron for a long time to get my hair in order. I highly recommend keratin for girls with damaged hair!

Rules for choosing products with keratin

When choosing a product with keratin, it is important to pay attention to the composition of the product:

1. Hydrolyzed keratin is suitable for hair, because... it penetrates deeper into the hair structure and is washed out more slowly. Keratin in its pure form can only strengthen in the structure of the outer shell of the hair and is washed off after the first wash.
2. In the composition, keratin should occupy a position at the beginning or middle of the list of product components.
3. Choose products without formaldehyde or with its permissible content - no more than 0.2%

Homemade keratin mask

A gelatin-based mask is a good alternative to the expensive keratinization procedure in the salon. Suitable for all hair types.

Ingredients:

1. Gelatin - 25 g.
2. Hair balm – 25 g.
3. Water - 45 ml.

How to cook: Stir gelatin in water. Place the mixture in a water bath, stir until the gelatin is completely dissolved. Add hair conditioner to the mixture at room temperature. Mix the gelatin mask well. Hair balm can be replaced with burdock or castor oil.

How to use: Wash your hair with shampoo. Apply the mask to your hair using a hair coloring brush. Wear a shower cap or wrap your hair in cling film. Wrap your head in a towel. The duration of the mask is 40 minutes. Rinse off the mask with cool water so that the gelatin does not dissolve from the warm water and is not washed away.

Result: Collagen and keratin contained in gelatin fill microcracks in the hair, smooth out curls and laminate them along the entire length. Strands become smooth and soft after the first use of the mask.

What to remember

1. Ask your specialist about the composition of the keratinization preparation before the procedure.
2. The duration of the effect of hair straightening with keratin depends on the condition of the hair and care for it after the procedure.
3. Keratin makes strands smooth and shiny, but weighs them down and removes volume.
4. The salon keratinization procedure is not suitable for fine hair.

A chemical compound - liquid fibrillar protein - with strong molecular bonds is called keratin. When applied to the hair, it completely covers the surface of each keratin rod, penetrates the pores and damage - if any - fills them. That is, by replenishing natural protein, it restores the structure.

After the procedure, the hair acquires a healthy shine, wavy curls are smoothed out, and it becomes easier to comb and style your hair. Another benefit of keratin for hair is that after it it reacts less to unfavorable natural factors and becomes soft to the touch.

Unfortunately, keratin straightening has to be repeated quite often. The effect of the artificial compound is short-lived - no longer than 3 months.

Is it possible to constantly use keratin, and is this procedure harmful?

Harm of the procedure

How and where is keratin applied to hair?

Manipulations are performed in the salon and at home, and if you follow the rules and choose an expensive product, the harm from applying the substance can be minimized.

Heating the keratin is an important condition for uniform application - the heating temperature reaches 230°C. For hair, such heating is severe stress - the structure is disrupted.

When the protein compound melts, formaldehyde is released - in hairdressing salons, clients and hairdressers are offered to use personal protective equipment - a respirator. Formaldehyde is a potent carcinogen. In cheap products its volume reaches 10%. You can minimize the harm from hair straightening with keratin by purchasing expensive products - their formaldehyde level is 0.2%. However, this significantly affects the cost of the service.

Most consumers, when asked why they need keratin, answer that it is to straighten their curls. When applying additional coating, the strands become heavier, which means the load on the hair follicles increases significantly. This influence weakens them.

Visually, the volume of hair decreases, the strands fit closer to each other, and become dirty faster. They have to be washed more often, and this is harmful in itself - it stimulates excess sebum production.

Before studying the instructions on how to use keratin correctly, you need to carefully study the contraindications. The product should not be applied to the hair of pregnant women, during lactation, or with problems with the respiratory system.

Benefits of keratin for hair

What are the benefits of keratin for hair? How is this stretching useful?

Correctly performed manipulation does not destroy the structure of the hair, and it becomes visually healthier and actually more manageable; it is easier to style it. The appearance becomes well-groomed, even if the hair is damaged, the hair structure is disturbed, you can not hesitate to loosen your curls - negative changes become visually invisible.

If the strands are dyed, the color does not fade for all 3 months - it remains just as rich. Keratin is needed for those who suffer from split ends. It reliably seals the delamination.

If you perform the procedure at home, its cost is significantly reduced. You can handle the manipulations yourself. You just need to purchase expensive compounds so as not to expose yourself to the harmful effects of formaldehyde fumes.

• wavy hair is dry and brittle, has a porous structure;
• abused coloring agents, which led to weakening of the strands and their damage;
• for coarse, unruly hair.

If sebaceous secretion is produced in excess, it is better to avoid using keratin. This will visually make your head greasy - it will look unkempt.

Algorithm for applying liquid keratin for hair at home

Tools for the procedure should be prepared in advance.

Required accessories:

• round hair brush - you need to choose one so that the strands do not get tangled and do not get stuck on the needles;
• spray;
• iron;
• towel;
• convenient hairdressing clips that allow you to collect and secure all the strands.

To perform the extraction directly:

• special product with keratin;
• shampoo and conditioner with the same substance.

It is advisable that all products be from the same cosmetic line. It is advisable to purchase a product with keratin at a beauty salon or professional store. It is necessary to avoid purchases at the bazaar from an unknown manufacturer. An increased content of formaldehyde in the substance can cause an attack of bronchial asthma.

The price of the set is quite high. Depending on the length of the hair, it is enough for 6-10 procedures, that is, for 2 years - no less. Therefore, you should pay attention to the shelf life.

Algorithm for applying keratin to hair.

1. Wash your hair with keratin shampoo, applying detergent 2 times - no less.
2. Excess moisture is blotted with a cotton towel.
3. Comb thoroughly - the comb should pass freely through the strands.
4. All hair is collected at the crown, pinned up.
5. The keratinization solution is poured into the spray bottle. The instructions usually indicate how much product is needed to process strands of a given length.
6. Thin layers of hair are removed from below, from the neck, and keratin is evenly applied from a spray bottle.
7. Then comb it, evenly distributing it.
8. The entire hair is processed sequentially - first from bottom to top, then from the crown to the temples. Paint is usually applied in a similar manner.
9. You need to wait about 15-18 minutes for everything to be absorbed.
10. Thoroughly dry the strands with a hairdryer and straighten them with a straightening iron, exerting a stretching effect.

After completing the manipulations, apply a serum or balm with keratin. What is the final stage for? Hair needs to be nourished.

Hair care after applying keratin

As one of the advantages of the procedure, they indicate the ability, after keratin straightening, to carry out styling using thermal effects and dye the hair in any color with dyes of any type.

It really can be done, but!

• You can’t wash your hair before 3 days!
• It is possible to think about changing your image by changing the color only 2 weeks after the procedure.
• At least 2 days must pass before styling with thermal agents.

In the future, you will have to abandon detergents and dyes containing sodium chloride or sulfates. You will have to avoid high humidity for 72 hours. If it’s raining outside, you’ll either have to sit at home or coquettishly try on a polyethylene cap – these are offered for showering.

Failure to comply with these conditions will lead to the integrity of the coating being compromised, and it will be possible to state that efforts and resources have been wasted.

Light keratin treatment

If you are afraid to do keratin pulling, then you can buy shampoos and balms with keratin and - using them 2 times a week - make it easier to care for damaged, dry hair or get rid of excessive waviness.

Keratin shampoos:

• moisturizing effect - "Equave", "Hydro Detangling Shampoo", "Revlon Professional";
• mild cleansers – "Extreme Makeover Kit", "Mild Detox Shampoo", "Smoothness and Shine" from Nivea, "Revlon Professional";
• restorative effect – “Pro-Keratin Refill”;
• straightening – "Style Masters", "Frizzdom Keratin";
• for sealing split ends - "Extreme Makeover Kit", "Cuticle Sealer Shampoo".

Curly locks, which are unruly and intertwined, create especially many problems for girls. It takes a lot of time to straighten them at least a little with the help of an iron and put them into a beautiful and neat hairstyle. But the price of this procedure is also high: damaged strands, dull and lifeless. A way out of this situation may be keratin hair straightening. The procedure not only smoothes the hair, but also restores it, returning it to its former glory.

What are the benefits of keratin

Hair contains 80% keratin, a special protein responsible for its healthy appearance. But frequent use of detergents leads to its washing out. Hair dryers, curling irons, straightening irons, elastic bands and hairpins cause hair to become faded and begin to fall out more actively. Dry and brittle, they do not grow so quickly. The hair straightening product contains liquid keratin, which penetrates into each hair, nourishes and fills the void. The hair is straightened, its appearance becomes much better, it is easier to comb and style – simply, quickly and pleasantly.

Thanks to keratin, the hair becomes thicker, its surface is covered with a film, receiving protection from the adverse effects of the external environment, the curls acquire shine and attractiveness. The results of using keratin can be observed immediately after the session. It stays on the hair for up to 3-6 months (the structure of the hair and its care play a role). Previously, keratin hair straightening was done only in salons, but now the event can be done at home.

The difference between salon straightening and home procedure

Keratin straightening is quite an expensive undertaking. The longer the curls, the higher the price. And hair care products after the session are not cheap. Therefore, many people decide to carry out keratin straightening at home, although they will not be able to get the same effect as in a specialized institution. One of the reasons is the difference in the compositions for use, and the process itself is also slightly different.

A kit for hair straightening with keratin is more expensive than a service in a salon, but its capacity is enough to carry out several procedures (from 5 to 10, depending on the length of the hair and its structure). At the same time, there is an opportunity to save some time.

Whether or not to decide on a keratin straightening procedure

For those who have not yet undergone keratative hair straightening, but are already thinking about it as a radical opportunity to change their image and straighten their hair, here is a selection of the advantages and disadvantages of this process.

Positive points:

• the product does not contain harmful or highly toxic substances;
• there is a significant improvement in hair condition;
• the ends do not split, styling is done quickly, dry hair goes away;
• the hair is not weighed down and is able to “breathe”;
• Perm is not contraindicated;
• the following straightening procedure only enhances the effect.

Negative aspects include the high cost of the procedure, especially if it is carried out in a salon, and the short duration of the effect - only up to six months.

How to perform a keratin straightening procedure at home

If you still decide to conduct a session yourself, you should buy only a high-quality composition, preferably one that is used by professionals in beauty salons. First, it is better to look for reviews about the product on the Internet and carefully read them. Only then buy it.

Before starting keratin hair straightening, prepare the necessary materials:

1. Deep cleansing shampoo, that is, a peeling shampoo that cleanses hair from impurities left by styling and coloring products, from silicone and chlorine contained in water.
2. Product containing keratin. Can be enriched with proteins and vitamin complexes for more effective protection and recovery.
3. Sprayer for evenly applying the solution to the hair. Otherwise, it may result in overdrying, because after using deep cleansing shampoo they become less protected.
4. Hair straightener, preferably with a ceramic or tourmaline coating and the ability to heat up to 230 degrees. At lower temperatures, keratin will not penetrate the hair.
5. Hair dryer, which is equipped with a gentle drying mode and cool air to avoid hair injury.
6. Hair clips, rubber gloves, wide-tooth comb, non-metallic cup, brush for applying the mixture.

Precautionary measures

The keratin straightening procedure is not recommended for women during pregnancy and breastfeeding, because the formaldehyde contained in the product, when heated, releases a toxic substance - formaldehyde. To avoid unexpected reactions of the body to formaldehyde, it is advisable for all women to use protective equipment: a protective mask or a cotton-gauze bandage.

To protect your ears from accidental burns from the iron, it is recommended to cover them with special pads.

Sequence of the procedure

Before carrying out the procedure, wash your hair thoroughly with a deep cleansing shampoo, preferably twice, in order to ensure that dirt is removed. Dry them with a towel and dry them with a hairdryer so that they remain slightly damp. After this, comb the hair thoroughly, distributing it into strands 3 cm wide and of equal thickness, securing with clips to avoid tangling.

Pour keratin into the spray bottle. The amount of composition depends on the length of the curls, on average it is 100 ml. Spray the solution onto the strands one at a time, moving 1 cm from the root. It is very important to use the optimal amount of keratin, because a smaller volume will not saturate the hair to the required extent, and an excess will lead to excessive oiliness, and they will have an untidy appearance. After applying the product, comb the strands.

You need to keep the keratin mask for 15 - 30 minutes, giving it a chance to absorb. Dry with a hairdryer at the lowest possible temperature.

Set the temperature on the hair iron to 230 degrees. If your hair is colored light, then 200 degrees will be enough. Keratin straightening begins with individual thin, 1-1.5 cm wide, strands. Go through each strand at least 5 times. After the procedure, comb your hair carefully.

How to care for your hair after the procedure

The straightening procedure is completed. Now, in order for the effect of keratin hair straightening to last longer, you should adhere to some important points:

• do not wash your hair for 3 days after the procedure, forget about styling products: gels, varnishes, mousses and others;
• do not use hair accessories for at least 3 days: headbands, barrettes, elastic bands,
• make sure that the hair does not break;
• refrain from wearing a hat and glasses;
• Protect your hair from any chemical treatments for at least 14 days, do not worsen its condition by dyeing, highlighting, glazing and other procedures;
• It is recommended to wash your hair with a sulfate-free shampoo to avoid washing out the keratin composition;
• during this period, contact with salt water is undesirable;
• use a protective serum that helps preserve keratin.

Human hair is 85% keratin. And if the body cannot independently synthesize this substance in sufficient quantities, then the hair becomes dull, lifeless and brittle. In this case, help is needed in the form of special masks or professional keratin products.

What is keratin?

Keratin is a special protein that is found in the skin, nails, teeth and in maximum concentration in hair. It is produced by the body thanks to special precursor cells - keratinocytes. And if any malfunction occurs in their work, then keratin can become sensitive to many factors. As a result, its basic properties and functions are violated - mechanical strength and protection from various damages.

Thus, we can conclude that maintaining optimal levels of keratin in the hair will help make it strong and protected.

For healthy hair, it is important to both act on it from the outside and nourish it from the inside. It is necessary to ensure that the diet contains a larger amount of both plant and animal protein. Sulfur, nitrogen, silicon, and B vitamins (in particular B6) also participate in the production of keratin. That is why a trichologist often prescribes a blood test for the above indicators and, if necessary, appropriate medications.

Benefits of keratin for hair

External care should consist of products with additional keratin. Its molecules can penetrate deep into the hair structure and fill all voids and damage. Therefore, when choosing hair cosmetics, you need to carefully look at its composition, first of all, at the position of the word keratin in the list. The lower it is on the list, the lower its concentration in the product.

Modern professional products with keratin can act on individual damaged areas. And some of its types can rejuvenate the intercellular space of the hair, creating an additional protective film on each of them.

Keratin hair strengthening

Keratin hair strengthening is a fairly popular salon procedure. Compaction and restoration of their structure leads to the appearance of a smooth, flowing, shiny fabric even in place of brittle, weakened and frizzy hair. This is why the procedure is often called keratin straightening, although its main task is to regenerate the hair shaft and create a protective outer layer.

Keratin straightening has its pros and cons.

How does keratin hair straightening happen in a beauty salon?

There are two keratinization technologies in beauty salons: American and Brazilian. The first is preferable due to the almost natural composition of the drug and the absence of formaldehyde in the composition. But the Brazilian technology is still more popular due to the fact that the results last longer and the prices for the procedure are lower.

Procedure technique:

1. The hair is carefully combed with a fine-toothed comb.
2. Then they are washed with a special shampoo. As a result, they are cleansed of any type of impurity, and the scales on the hair open and lift.
3. Professional liquid keratin is applied.
4. The hair is dried with a hairdryer for a long time without styling. Some salons send the client under climazone for this purpose.
5. After a certain time, the hair is divided into small strands and begins to be straightened with a special iron. The temperature at which the hair scales are sealed is 230°C.

So the attitude towards keratin strengthening is ambiguous even among professionals. On the one hand, it allows you to improve the quality of your curls for a long time and protect them from external damage. On the other hand, the effect is too aggressive (chemical plus thermal), which not every hair can withstand without loss.

Hair straightening products at home

Due to the high toxicity, salon restoration with keratin is prohibited from doing on your own. At the same time, homemade keratin hair straightening products most often last until the next wash: they contain a low concentration of this protein and cannot retain it for a long time.

The problem was solved by the Peruvian company Kativa, a world-famous manufacturer of professional hair care products. A real scientific discovery was the invention of NICTECH technology for hair straightening without ironing - a special composition with keratin, liquid pearls, natural oils, as well as a complex of amino acids and innovative safe polymers.

The preparations themselves are healthy and nutritious. However, the main advantage of IRON FREE hair straightening kits is the complete absence of formaldehyde and activation of the composition with a regular hair dryer, i.e. no high temperatures that damage and dry out your hair! This procedure is easy to do yourself, and the results will last as long as 4 weeks. At first glance, it is significantly less than salon straightening. However, if you calculate the cost of such straightening, it will turn out to be even more profitable. And, of course, much healthier for curls.

Kativa IRON FREE hair straightening kits without ironing and formaldehyde are presented in three variations.

Benefits of Kativa hair straightening kits:

• Only natural ingredients and the absence of any aggression;
• The effect of strengthening, straightening and moisturizing hair;
• Reduce unnecessary volume, tangles and frizz;
• Additional thermal protection;
• Makes combing and styling easier;
• The whole procedure takes no more than an hour;
• A “memory effect” is created; in the future, the hair itself takes on the desired styling after regular washing.

Kativa has also developed special products for aftercare after hair straightening without ironing. The series includes shampoo, conditioner and mask that support and prolong the results.

Kativa IRON FREE is an excellent solution before a long business trip or travel, because while traveling there is no opportunity to carefully style your hair every day. After such nourishing care, they become stronger, shiny and elastic, protected from temperature and mechanical damage, so the kits are recommended to be used as a preventive measure, especially after a seaside holiday, frequent dyeing or visits to the pool.

Hair care rules after keratin straightening

For the longest possible effect from keratin treatment, it is necessary to follow certain recommendations.

1. After the procedure, you should not wash your hair for 3-4 days. They may seem dirty and greasy, but you need to endure this, otherwise the keratin will not integrate into the hair structure.
2. If a woman dyes her hair, it is better to do this before the procedure, then the color will be bright for a long time. After keratin straightening, you need to wait at least 2 weeks.
3. For washing, you must use special sulfate-free shampoos. They gently cleanse hair without damaging it.
4. It is advisable to dry your hair naturally and also avoid aggressive styling.

These rules apply to both salon keratinization and home hair straightening with Kativa IRON FREE kits. Make a choice in favor of useful procedures and beautiful hair!

Beauty is like a precious stone: the simpler it is, the more precious it is:)

Content

Today, many women straighten their hair using professional products. One of them is hair keratin - a fibrillar protein (liquid or solid), which can be purchased at a pharmacy or specialty store. Keratin is included in many hair care products or sold separately in ampoules. With it you can not only straighten strands, but also carry out restorative procedures.

What is keratin

This is a natural protein found in hair, nails, and keratinized areas of the epidermis. Under the influence of high temperatures (hair dryer, ironing, curling) and chemical influences, the strength of keratin decreases. The substance is capable of restoring and protecting our hairs, making them smooth and beautiful, so it is very important to compensate for its deficiency with the help of special products.

Compound

Keratin contains amino acids that can be converted into different compounds. This ability gives a substance the ability to take on different states: liquid or solid, dense or soft. In addition to amino acids, it contains cystine, cysteine, glycine, alanine, and a sulfur-containing amino acid is responsible for its strength. To replenish amino acids, the body needs sulfur, nitrogen, silicon and other trace elements that are found in animal protein.

What does keratin do to hair?

Keratin hair care is necessary to restore its structure from the inside. The molecules of the substance penetrate deep into the hair, filling the intercellular space and microcracks, restoring its elasticity, strength and shine. In addition, keratin moisturizes hair, retaining moisture inside, prevents split ends, provides elasticity, and participates in the production of collagen. The result of keratinization can be seen in the “before” and “after” photos. The result lasts for up to 3 months, since the product tends to wash out.

Is keratin harmful to hair?

In addition to the many positive properties of keratin, straightening with its help also has some negative aspects:

1. By impregnating the hairs, the substance makes them heavier, as a result they may fall out.
2. As a result of straightening, the hair quickly becomes saturated with sebum and has to be washed more often.
3. It is not the keratin itself that gives shine and elasticity to the hair, but the formaldehyde contained in cosmetics. This substance has harmful effects on the body.

Hair straightening with keratin

The main function of the keratization process is to fill the cracks in the hairs with a substance and seal the scales under the influence of a temperature of 230 degrees. As a result, the hair keratin composition is held inside the strands, providing a kind of frame and keeping them straight. The procedure can be carried out in the salon or at home, while observing technology and safety rules. It consists of the following actions:

1. The hair is combed with a fine-toothed comb and washed with a special shampoo that lifts the scales on the hairs.
2. A preparation containing keratin is applied.
3. Blow-dry hair without styling.
4. Straighten with an iron at a temperature of 230 degrees, dividing the hair into separate strands.

In the cabin

The keratin treatment products used in the salon are of higher quality, contain a minimum of aldehydes, and have a minimum negative effect on the hair. One of the advantages of the procedure is the possibility of combining keratinization with coloring. The cost of the service in Moscow is as follows:

A number of advantages do not make keratinization completely safe; the procedure also has a number of disadvantages:

1. Evaporation of formaldehyde, which occurs when strands are exposed to high temperatures. Inhaling these vapors is harmful to health.
2. After being coated with keratin, hair becomes heavier and may begin to fall out.
3. As a result of the same weighting, hair volume is lost.
4. Rapid contamination of the scalp occurs.

At home

The process of performing home keratization is no different from the salon procedure, except for the financial aspect. The service in the salon is not cheap, and purchasing products for the procedure at home will cost even more. However, the volume of the purchased product will be enough for more than one keratinization. As a result, compared to salon hair straightening, home straightening will cost less. Improperly performing the procedure can severely damage your hair. Some girls do keratin straightening using mask recipes with gelatin.

How to choose keratin for hair

If you decide to undergo keratin therapy at home, consider the following recommendations for choosing keratin for hair:

1. Formaldehyde content. For curly curls, a high percentage of the substance is needed, for non-curly ones, a low percentage.
2. Read what temperature is needed for the result to be of high quality. Your iron should reach the specified number of degrees.
3. Choose products from manufacturers that have received many positive reviews.
