Is it worth doing keratin hair straightening

How does keratin hair straightening?

Hair is composed almost entirelyHuman Hair and the Impact of Cosmetic Procedures: A Review on Cleansing and Shape-Modulating Cosmetics of the protein keratin. Therefrom and composed cuticle - Transparent armor in the form of tightly adjacent keratinized scales and cortex - thick core hair chains of amino acids.

Chains are held together and keep the shape of hair with different connections: hydrogen, ionic and disulfide. Last - the most powerful. They do not destroy the water, a conventional shampoo and hairdryer - only alkali and high temperature.

the hair structure is setNanoscale characterization of human hair and hair conditioners at the very beginning of its growth - in the hair bulb. If the bulb is straight and symmetrical amino acids foothold smoothly and the hair will not curl.

If the bulb is asymmetrical, the hair is wavy.

Means for keratin straightening help break down some of these rough disulfide bonds and restore them to a different position.

In these formulations have Keratin taken from the wool of sheep and broken into small pieces, chemicals that release formaldehyde, and various silicones in hair balm.

In addition, high temperature seals the hair cuticle, so long keratin remains inside.

But formaldehyde is harmful, is not it?

It depends on the quantity. Secure concentration of formaldehyde in air isOn approval of the hygienic standards GN 2.1.6.3492-17 "Maximum permissible concentration (MPC) contaminants in atmospheric air urban and rural "(as amended on 31 May 2018 of the year) 0.05 mg / m³.

However, most studies have been conducted in industries where formaldehyde levels rose to 3-5 mg / m³. In the salons of the beauty comes concentrationCharacterization of formaldehyde exposure resulting from the use of four professional hair straightening products. a maximum of 1.4 mg / m³.

This is much higher than permitted by the rules, but if you breathe formaldehyde one o'clock every three or four months, it most likely will not affect health.

And you can do without formaldehyde?

You can not. Formaldehyde-free keratin sheep will not be able to establish strong ties with the native protein of the hair, and then quickly leave him.

manufacturers love to write on the packaging formaldehyde free. As part of such tools you will not find formaldehyde (Formaldehyde), because:

• Formaldehyde is not there, but there are substances that produce it when heated, for example, Timonacic acid (thiazolidinecarboxylic acidHair Smoothing Products That Could Release Formaldehyde) Or Oxoacetamide carbocysteineNon-Formaldehyde Based Smoothing Treatments.

What happens during the procedure?

First head shampooed deep cleaning with a high content of alkali. Means washing away your leftovers masks and balms and opens the hair cuticle.

Then on damp hair for 30-40 minutes to apply the composition to keratin straightening. Next, the hair is completely dried hair dryer, and each strand is straightened utjuzhkom repeatedly warmed up to 180-230 ° C.

The locks were then washed with shampoo neutral pH and applied to a mask or balm. Rinsed them and again dried hair.

And the hair will not be affected?

Rectification inevitably damagesMechanical characterization of curly hair: Influence of the use of nonconventional hair straightening treatments hair texture: breaks the disulfide bonds.

Some of these connections is restored at the expense of sheep keratin. A cuticle, such as disclosed protruding bumps utjuzhkom sealed and polished and silicone oils, which are part of means. The light is reflected from a smooth surface and the hair shine like in advertising shampoo.

But over time, the cuticle is slightly opened, new disulfide bridges are crumbling and washed acquired keratin.

When washing out the hair keratin are weakened and can break, because the disulfide bonds are destroyed. That hair remained strong and beautiful, keratin straightening must be done regularly.

The degree of hair damage is dependent on whether the master erred.

What mistakes can make the master?

In most cases, masters correctly determine the degree of damage to the hair or no diagnosis is performed.

Because of this, they are incorrectly selected ironing temperature and make a major mistake. Porous strands from sticking out and badly damaged cuticle can not straighten very hot utjuzhkom. If you burn the hair at this point, after washing keratin they will look worse than before the procedure.

If thick hair, with a tight-fitting cuticle, you can use the temperature higher, or penetrate into keratin and little curls remain.

Also, before straightening the strand must be dried 100%. If the master undercured hair, high temperature ironing can severely damage their structure.

Whether the effect is maintained for a long time?

It all depends on the quality of the procedure and further hair care. 24-72 hours after the rectification can not be wet hair, remove them to the tail, use hair clips.

In the future, better use of Daily Conditioner or other soft means to care.

We recommend a Daily Conditioner any professional series or a professional shampoo for colored hair. These funds are not washed out of keratin, gently cleanse hair and suitable for use after the procedure.

If done correctly, the hair remains straight and smooth 3-4 months. The effect of the follow-up procedures can be stored up to 6-8 months, because the keratin accumulates in the hair.

What if I'm not going to repeat the procedure?

If the procedure is carried out efficiently, 3-4 months the hair will return to its previous state with minor injuries. If the master perezhog hair, they become worse after washing keratin.

Keratin straightening - it's expensive?

It all depends on the particular compartment, the length and thickness of hair. You can meet and 2 000, and you can spend more than 20 000.

Maybe then home to do?

Compositions for keratin straightening can be bought in a store of professional cosmetics, but it is good to straighten hair houses almost impossible.

After all, you need to evenly apply the composition of the whole head, stepping back from the roots 2 cm. Then we need some time to straighten the strands ironing, not missing any of them. Do it without help - it's like that cut themselves appendicitis.

In the worst case, you can burn the hair, and after washing the keratin they will become a piece of hemp.

It is fair to say that it can make and bad master, but in the cabin, you still run the risk of less.

So do me a keratin straightening or not?

Yes, if you have thick curly hair and you hate them. As the stylist Daria Kilina, it is better to do keratin straightening time in half a year, than every day to spoil your hair dryer and curling irons and spend it on a lot of time.

But people with weak and bleached hair is better to abandon the procedure. High temperatures can damage the cuticle so that after washing keratin hair will start to crumble.

What can you do instead?

If you want to solve the problem of "dandelion", not to straighten curls, try other ways: moisturizing balms and masks, tools, smoothes the cuticle or salon treatment without ironing. The result will not be as noticeable and long, both from keratin, but you certainly do not mess up your hair.

We do not treat the hair and reconstruct its visible part, provide a neat appearance. Now there are a lot of procedures in addition to keratin: Botox, reconstruction, nanoplastika, cold recovery, detox the scalp, many spa programs. To choose the right, you need to consult a specialist.
