Proteins are the very foundation of your hair's structure. In fact, natural hair is primarily composed of keratin, accounting for over 90% of its makeup.
The presence of proteins thus helps build hair and protect it from external aggressions related to the environment or even multiple manipulations.
Proteins act by filling the gaps that appear on the hair's surface, which helps to sheath it. This type of care is characterized by the presence of active ingredients such as (hydrolyzed) keratin, coenzyme Q10, or silk or soy proteins.
A lack of protein is characterized by brittle, dull, and devitalized hair.
Relaxing or any other chemical treatment breaks this structure by destroying keratin. Providing proteins regularly is essential for hair balance, giving it strength and thus reducing breakage.
Thus, it is important to provide proteins during these times: - before and after any "treatment" (relaxer, straightening, braids, heat use…), to strengthen and repair hair; - after shampooing to regularly rebuild hair due to daily damage.
