Keratin hair straightening: pros and cons, consequences. How and by what means. Photo of results

The constant action of negative external factors on the hair leads to fragility, split and hair loss. To strengthen and deeply restore hair, a special procedure has been developed - keratin straightening, which has both positive aspects and some imperfections.

What is keratin straightening

Healthy hair has special scales that adhere tightly to it. They retain nutrients inside, and also protect hair from negative environmental factors: wind, sun, dust, exhaust gases and cold. When these factors act constantly, the scales open slightly, weakening the defense.

At the same time, the condition of the hair begins to deteriorate markedly: fragility, dryness, sectioning and hair loss appear. This is due to the loss of their natural building material - keratin, as well as vitamins. Keratin straightening is based on the effect of their natural component on the hair structure - keratin.

This liquid protein, penetrating inside, permeates the injured areas, filling empty areas.

It is also able to glue open hair scales, which helps to restore their protection and healthy appearance. This effect is due to the technique of the procedure and the property of the protein: when exposed to high temperatures, it thickens and forms a sticky film on the surface of each hair.

Keratin treatment refers to periodic procedures, since the preservation of its effect depends on the composition of the mixture used, the thickness of the hair and the skill of the specialist. On average, straightening is maintained for 4-6 months.

Keratinization has several types:

• American: formaldehyde-free straightening. It is the safest and has few contraindications, but its cost is very high.
• Brazilian: formaldehyde straightening. The procedure is carried out with the use of formalin and requires, after its completion, to wash the hair only with regenerating shampoos based on keratin protein.

The result of the procedure

According to the different hair types, keratinization gives different results, which almost always have only positive effects.

Mechanism of action

Keratin hair straightening, the pros and cons of which are based on the action of chemical compounds, has a general principle of action that depends only on the properties of the protein protein.

Human hair consists of:

• proteins;
• water;
• lipid components;
• salts.

Experiencing the constant influence of all negative factors, they lose some of the keratin. When hair grows back more than 20 cm, it loses its ability to restore the required protein level. At the same time, they become brittle, dry, split ends and a lifeless look.

The keratin protein found in straightening formulations is embedded in cracked walls and hollow areas. This makes the hair soft and shiny. Keratin then envelops the outer part of each hair.

Under the influence of the hot plates of the straightener, excess moisture is removed from the applied composition, while the protein itself thickens, structures and polymerizes, giving the curls elasticity and strength.

Under the influence of an evaporating solvent, the keratin is sealed inside and outside of each hair. The resulting layer protects the curls from ultraviolet radiation, overdrying and absorption of harmful substances for a long time.

After a while, keratin is washed out of the hair on its own, which allows you to repeat the procedure without risking spoiling it with various chemical mixtures. Keratin hair straightening, the pros and cons of which form contraindications and even recommendations for carrying out, requires prior consultation with a specialist.

So, the procedure is not like people:

• with damaged skin;
• with a tendency to allergies;
• with malignant formations;
• with baldness;
• with diseases of the respiratory organs.

Keratinization is recommended for people with disobedient curls that have lost their natural radiance.

Benefit

Keratin hair straightening (pros and cons are characterized as fairly safe factors for hair health) is cumulative and is carried out at least 2 times to achieve an ideal appearance.

At the same time, hair deteriorates significantly less than with daily styling with an iron, since, together with the negative effect of high temperature, the protein immediately and completely restores its structure.

Advantages of keratin straightening:

• Hair is transformed. They become not only shiny, but also elastic, soft and obedient.
• Their structure is being restored. Keratin protein fills in all empty and damaged areas of each hair, replenishing the loss of essential substances. Thanks to the layer formed on their surface, they are protected from the harmful effects of external factors.
• The variety of styling is not lost. If desired, the hair can also be curled, it will straighten on its own after washing your hair.
• Makes styling and combing easier. After keratinization of the hair, their tangling and electrification disappears. The resulting straightening effect lasts a long time, which eliminates the need for constant use of the iron.
• Split ends disappear for a long time. The protein, hardening upon heating, forms a dense film that seals the cut sections.
• Hair receives useful trace elements, nutrition and moisture. Straightening formulations contain vitamins, mineral complexes and nutrients.
• The effect of healthy hair lasts for several months. Since keratin is washed out gradually, the effect of healthy hair lasts for about 4 months.

  

• No harm to curls. Keratinization heals the hair without harming it even when exposed to high temperatures.

Harm

Keratin hair straightening has not only positive aspects, but also some disadvantages. It can harm thin or loose curls.

Among the cons are:

• Feeling uncomfortable for the first couple of days... After keratinization, shampooing is prohibited so that the effect can be fixed. Also, the hair at this time seems dirty and greasy.

• Care of curls becomes more complicated. Hair will have to be washed only with special products that do not contain silicone, parabens and sulfates, which contribute to faster washout of keratin.
• Loss of natural volume and possible hair loss... Hair is greatly smoothed and heavier, which will not allow you to create a lush hairstyle. Due to this, the load on the bulbs increases, which can provoke their damage and hair loss.
• The composition can cause poisoning... It contains various chemical compounds. There is a risk of burns, poisoning or suffocation when using untested formulations.
• As part of straightening products contains formalin... It is a toxic substance and is classified as a strong carcinogen. When choosing a product, they carefully study the composition of the product, the proportion of formaldehyde should not exceed the permissible 0.22%.

Preparatory activities

Hair straightening does not require special preparation, it is only necessary to thoroughly wash your hair before keratinization, washing off all sebum and residues of styling products.

It is worth remembering that there are a number of nuances due to which the master can shift the appointed time of the procedure:

• Newly dyed hair, as the dyes fill the hair structure and the keratin protein cannot fix. The result of this procedure will be a lack of shine and uneven coloration. After it, it is better to do keratinization after a few weeks.
• Applying Botox to the hair will also delay keratinization by 5-6 months, as high temperatures are used during straightening. The Botox they act on can cause hair allergies and weakening. Also, carrying out both procedures one after another threatens the effect of dirty and thin hair.

Execution technology

The process of carrying out keratinization is a very laborious process that requires a lot of skill.

It consists of 4 stages:

1. Preparation for the procedure... The master thoroughly rinses the head with a special professional shampoo for deep cleansing, soaks it on the hair for 2 - 5 minutes, and then rinses it off and dries the hair with a hair dryer to light moisture.
2. Keratin application... Without affecting the roots, the specialist applies the selected composition over the entire remaining length of the hair. Then he brushes the hair and leaves the product on for 25 minutes.
3. Cold drying... The master dries the hair with cold air using a hair dryer.
4. Straightening... The hairdresser uses a professional iron to pull out the strands of hair. At the same time, the temperature of the plates reaches 230-250 degrees, which allows keratin to quickly and completely structure and fix.
   

If a person has thick or too coarse hair, the procedure is carried out 2 times.
