What is hair keratin?

keratin is the name of the main protein in hair. keratin or protein is essential for thick and healthy hair and will make hair shine. This protein is less present in curly hair and this leads to dryness and frizz. Now if your hair is damaged, you can keratinize, revitalize your hair and give it new life. People with wavy, dry, brittle and unhealthy hair can strengthen their hair by keratinizing it.

Keratinizing hair is basically one of the common methods to improve the appearance and treatment of damaged hair. It should be noted that keratinization can reduce the damage caused by excessive dyeing, the use of hair dryers and conditioners, and so on. The right formula for keratinizing hair should be determined by experienced people. We recommend that you use substances that do not release formaldehyde. Because the released formaldehyde causes damage to the hair.

Some people think that keratin straightens hair, but it is completely wrong, keratin repairs hair cuticle damage and makes hair shiny and reduces frizz, and it is not just about straightening hair.

Types of hair keratin

In general, hair keratin is divided into two main categories:

  • Hair regenerating keratin
  • Brazilian keratin or keratin hair straightener

Is keratin treatment suitable for hair?

Keratin treatment; Considering all the disadvantages and advantages, is a useful method for hair restoration. So, if you are disappointed and tired of your hair, try this method to restore beauty to your hair and get rid of daily hair dryers.

What is the difference between hair keratin and hair straightener or relaxer?

There is no significant difference between the two methods and the goal of both is revitalization, freshness and hair health. But the solution used in these two types of keratin is different from each other. Hair keratin is usually temporary and disappears after a period of time. But relaxer is a permanent chemical method. Because the relaxer method is stronger and the hair shafts are broken and rebuilt, they are more likely to damage the hair.

Our school recommends keratin. Because keratin fills the pores of the hair, making the hair soft and shiny. Obviously, after a period of time (usually a few months) these substances are washed and removed from the surface of the hair and the hair returns to its previous state.

Performance in relaxers varies. Chemical relaxers break and regenerate hair shafts. This will make the hair weaker but have smoother hair as a result.

What are the complications and disadvantages of hair keratinization?

This method, like any other method that deals with chemicals, has disadvantages and there is a possibility of complications. These include:

High price

Keratin materials are usually expensive materials. On the other hand, because hair keratinization is time consuming, the cost of performing it is also usually high. Another important point is that after keratin treatment, hair needs to be taken care of, which is not cheap. For example, you must use sulfate-free shampoo, which is generally an expensive shampoo.

Short lived Durability

The durability of hair keratin varies from 2 to 3 months, depending on the material used. Of course, it may take a little longer depending on your hair type, but the change to the initial state usually takes place within 3 months, after which you will need to renew the keratin.

Possibility of hair damage

Since the keratin iron operates at high temperatures, there is a possibility that the hair will be damaged by high heat. This is one of the reasons why we recommend you to have an experienced hairdresser for this purpose. Of course, note that you must use good products with a reputable brand.


Formaldehyde is a carcinogenic chemical, and people who are constantly exposed to keratin inhale the gas will be exposed to the disease. As a result, it is recommended that formaldehyde-free materials be used to perform the keratinization process. Of course, the released formaldehyde is low and the amount is precisely mentioned on the package of materials used.

Allergic skin reactions

Some people may be allergic to the ingredients used in hair keratin and may develop inflammation as a result of using it. Do not forget to test some of the keratin on your arm or leg before doing it to make sure it does not have a negative reaction on your skin.

Special shampoos

To increase the durability of keratinizing hair, you must use special shampoos that are usually expensive and may cause skin allergies for the consumer.

Hair Loss

Regular use of keratin causes hair loss and it is recommended that you leave a gap period between the times you use keratin for your hair.

Possibility of allergies

keratin in hair, nails and teeth is a natural protein but the keratin used in keratinizing is not natural. As a result, it may cause allergies in some people, which usually irritate the eyes, and this is very rare.

Harmful to pregnant women

This procedure should never be done for pregnant women, as it is dangerous to the health of the mother and fetus.

What are the benefits of hair keratin?

Suitable for all types of hair

Fortunately, the keratin method does not impose any restrictions on people. This method is suitable for all types of straight, dyed, curly, coarse or fine, soft and curly hair.

No damage the hair

Possibility of hair damage through keratin is very small and its damage is much less compared to methods such as hair rebounding. When your hair grows, you will have your own same original hair and there will be no trace of keratin on your hair.

Easier styling

When you keratinize your hair, not only do you get thick and straight hair, but also you can style it much easier than before and style it any way you want.

Multiple beauty

In this method, you change so much that you may always want to have keratinized hair. The beauty of hair greatly affects the face.

Easy maintenance

Unlike many hair beauty methods, this method does not require much care, and if you use special and suitable products with keratinized hair, you can keep your hair keratinized for a long time.

Improve hair quality

As mentioned earlier, your hair structure works with a protein called keratin. As a result, you inject a required substance into your hair that improves the quality of its structure.

No more frizzy hair

People who have very wavy hair and a comb gets stuck between their hair, can have perfectly smooth and healthy hair by doing keratin and can comb it easily.

Methods and steps to do hair keratin

First of all, it is better to mention that you need three main products for keratinization. These three include the following:

  • Pre-keratin shampoo that opens hair follicles and is an alkaline shampoo.
  • The main ingredients of keratin in a bottle
  • Post-keratin shampoo, which closes hair cuticles and is acidic.

Step One: First wash your hair with pre-keratin shampoo and then you rinse your hair.

Step Two: At this point you should wait for the hair to dry, but not completely dry. About 20% moisture should remain in your hair. If you want to keratinize your hair with vitamins, you need to dry your hair thoroughly, but for normal keratin (Brazilian keratin) you do not need to dry it completely.

Step Three: Divide the hair into 4 to 10 sections. Note that more categorization is needed for better quality of the result. hair volume also is contributing factor on this issue.

Step Four: Pour the keratin ingredients into a bowl, use a brush to apply the ingredients to the hair. The point to keep in mind is that to apply keratin, you need to be a finger’s breadth away from the roots. Also, the layers you take to impregnate the material should be quite thin and be careful that the keratin material does not touch the scalp. Another point is that you should impregnate the entire surface of the hair with the material so that the thickness of the hair does not decrease when ironing.

Step Five: Wait about 20 to 30 minutes for normal hair and 40 to 50 minutes for coarse and curly hair until it affects the hair. At this point, comb the coated hair from top to bottom about every 8 minutes. You can also use a plastic hair cover to increase the effectiveness of the mixture.

Step Six: Note that, you should not dry or wash the coated hair with a towel, you should iron the hair on while it’s still coated in the mixture and after the timing is done you can dry your hair using a hair dryer.

Step Seven: After the hair is completely dry, prepare a keratin hair iron that generates high heat (about 400 to 450 degrees). Run regularly from top to bottom for one section, and when that group is done, move on to the next. It should be noted that this operation can be done with hair irons with a temperature of about 250 degrees, but certainly the quality of work is not similar to the case with 400 degrees. Each bunch of hair should be ironed about 7 to 8 times. Be careful not to choose a bulky handle, the selected handle should be slightly thicker. Do not worry about steam rising from the hair and continue your work. Experienced people believe that ironing should be done until no more steam is rising from the hair.

Step Eight: After keratin process, you should not soak your hair at all and do not wash your hair for up to 3 days. This is a bit difficult but you have to do it to have a good keratin. After this stage, you go home, you are not allowed to take a bath for three days. Also, do not tie your hair for better results.

Step Nine: During these three days, you are only allowed to use the hair iron. The heating iron should be at a gentle level. Do not apply any extra ingredients such as serum, hair mask, hair spray to your hair.

Step Ten: Now after these three days, wash your hair with acidic shampoo. If there is anything left of this shampoo, you can use it in the next few days.
