The birthplace of Keratin hair straightening is Brazil: local girls have their hair predominantly curly or very curly.Brazilian girls themselves did not always like this, so at the end of the zero one of the local masters developed a special composition, which allowed to straighten their hair almost forever than won folk love.Soon, these compositions under the brazilian Blowout’s trademark entered the American market, where they gained incredible popularity.
We explain how it works.To begin with, Keratin itself does not straighten the hair - it's just a protein.You get the effect at the expense of Formaldehydes - caustic compounds that penetrate the hair structure and destroy disulfide bonds in it, making hair supple.Disulfide bonds connect the amino acids of cysteine to create one molecule - a cystine that combines protein chains (own keratin) into a single whole - this is a visual scheme, how all this looks.By destroying disulfide bonds, you can make hair smooth or, conversely, cut it.The effect of the procedure, depending on the aggressiveness of the composition, can remain on the hair at least all their lives, even if they were originally super curly.
As the Keratin hair process occurs: in order for the composition to get as deep as possible, the hair is first washed with a deep cleaning shampoo with a high clip content, then applied a special composition and straightened with an iron at maximum temperature - a similar method is used for chemical curls.
Moreover, keratin then: the hair under the influence of alkali made of shampoo and Formaldehydes spoils strongly - become porous and brittle, so artificial keratin adds to the straightening compositions: it does not allow their hair to break, adds smoothness and brilliance to them, makes them obedient.
What is the difference between keratin converting and hair restoration
Initially, Keratin was used specifically for hair straightening.But the effect - brilliant and obedient hair - liked people so much that even girls with perfectly straight hair began to use this service, and stylists - to sell it under the name “Keratin Restoration”.In fact, the principle of action of both procedures is the same: you open the hair cuticle and drive keratin into it.The difference is in the aggressiveness of the composition: to straighten the hair for a long time, the master will use the formula with a high content of alkali and formaldehyde;To make hair just more beautiful - with less or without it at all.Sometimes Keratin hair of the master call the usual washing of the head with a mask for hair and keratin serum - the effect in this case will remain at best for a week.What exactly is offered to you by the salon, be sure to check with the master before the start of the procedure.
Is it harmful?
If in the description of the Keratin hair process the word "formaldehyde" was frightened of you - not in vain.In 2011, the FDA agency of the US Ministry of Health and Social Services issued a warning that the hair straightening means of some brands may be a danger to the health of the people who use them and the hairdressers who apply them.The reason was the unacceptable concentration of Methylene Glycol - a component that, when heated, emits formaldehyde gas dangerous for health (due to which there is a violation of the hair structure).Soon after, manufacturers of hair straightening have been forced to change the formulas of their products: modern analogues contain any much smaller concentrations of Methylene Glycol or its less harmful analogues.By the duration of the effect, they are significantly inferior to the versions of the past generation, but they are safe (at least approved by the Ministry of Health) both for customers and stylists.
How to protect yourself: do not buy products for home keratin hair in unverified online stores, on Chinese sites and in the transitions of the subway.We also recommend refraining from visiting strange salons like where “any haircut is inexpensive”, and if you doubt the origin of the composition, ask the master to show you the packaging.
An important point: not all hair is suitable for this procedure.If you have repeatedly bleached your hair, often curled or made it straight, we recommend that you refrain from keratin procedures - your hair may not survive this.Why?In any case, Keratin recovery is partly a traumatic procedure.And you will definitely notice its negative consequences even when artificial keratin is completely washed off - you will get porous and brittle hair.If the condition of the hair before the procedure was bad, after it will be even worse - this is the reason why people “sit down” not Keratin, so be careful.
