The goal of keratin treatment is to make hair look healthier, shinier and frizz-free. What do you need to know?
Keratin treatment, also called “Brazilian straightening”, is one of the most requested procedures for hair beautification. It consists of the application of a product rich in amino acids, which deeply nourishes hair fibers to restore hydration and shine.
It is recommended for dry hair prone to frizz. But also for people who want to go from a curly look to a smooth look. Of course, it should be used with caution, as it is not without its drawbacks.
What is keratin and what is its composition?
The body naturally produces keratin, a protein essential for healthy hair, skin and nails. However, in cosmetics, Keratin is a hair treatment whose aim is to repair the hair cuticle.
It is made up of 18 amino acids which modify the consistency of the hair. Thus, frizzy, rebellious, thick and very curly hair acquires a smooth, soft and shiny appearance which lasts between 4 and 6 months.
Currently, several formulas are marketed under the name keratin. They may contain a high or low percentage of this protein. From there it depends on whether the hair is Asian straight or with soft waves. Choosing one option or another depends on the type of hair, its needs and the desired look.
In any case, its main components are generally the following:
- Cysteine: it is a protein naturally present in hair. It helps to recompose the hair strands. In keratin treatment, the percentage is usually less than 2%.
- Formalin : This is one of the most controversial ingredients in this product. Although it creates a waterproof film on the hair, it prevents adequate nutrients from reaching it and weakens it. Currently, many formulas do not contain this substance.
- Glutaraldéhyde : only 0.1% is present due to its risk of toxicity. Its action is similar to that of formaldehyde.
- Panthenol: by penetrating into the hair fiber, it provides a long-lasting moisturizing effect.
- Silanetriol : it provides a thermo-protective effect which helps to increase the hair’s resistance to breakage.
- Shea Butter : some formulas contain this fat in their composition. It provides shine and extra protection.
Other ingredients include glycolic acid, ethanolamine, ammonia and sodium hydroxide. Although they help achieve the straightening effect, they are compounds that can leave hair dehydrated and lifeless. It is necessary to check that they are in minimum quantities. Finally, some presentations do not contain them.
