Chemical hair straightening

Of course, you can pull out curly hair every day ironing. But this method takes a lot of time and effort, withregular use spoils the hair, and its effectiveness is low - with the slightest increase in humidity, the hair again starts to puff and curl. That's why the Japanese specialists developed chemical hair straightening.

Chemical hair straightening - it's likechemical wave on the contrary. Special chemicals are applied to the hair (sodium hydroxide or ammonium thioglycolate), then - the fixative, and the procedure for applying the conditioner completes the procedure. Sodium hydroxide (rectifier) suitable for people with very curly hair. The rectifier operates as follows: penetrating under the cuticle, it softens the cortical layer of the hair, due to which the structure of the hair changes. The greater the concentration of sodium hydroxide, the more straight hair will be, but the higher the risk of damaging them. Effect ammonium thioglycollate (relaxant) much weaker. Sometimes used guanidine hydroxide, in terms of efficiency, it takes an average position. In addition to the active substance, the rectifier includes proteins, essential oils and vitamin C.

Chemical hair straightening can be performed by three kinds of formulations, depending on the strength of the effect of the composition and structure of the hair. For straightening hard and curly hair use high strength rectifiers on the basis of sodium hydroxide. Hair of medium undulation with a normal structure is straightened using medium strength rectifiers (thio-rectifiers based on sodium thioglycollate). And to straighten damaged, dyed and weak hair, rectifiers of a weak fortress with a content sulphide and ammonium disulfide.

Before starting chemical straighteninghair, the master thoroughly cleanses hair with a special shampoo and dries them. After 15 minutes, apply a straightener. If a rectifier of increased strength is used, the master can first apply to the scalp Vaseline cream - this will help to avoid burns. Having washed off the composition, the master treats the hair with a thermal protection spray and irones each strand along its entire length. Then the hair is applied to the fixator (neutralizer of the rectifier), they are thoroughly washed, the conditioner is applied and dried.
