What is the primary ingredient in most hair relaxers?

The primary ingredient in most hair relaxers is sodium hydroxide or ammonium thioglycolate. These substances are powerful chemicals used to break the disulfide bonds in hair, which are responsible for the hair's natural curl and wave.

Sodium hydroxide is a strong alkaline compound that alters the hair's protein structure, making it possible to straighten the hair. It is commonly found in traditional relaxers aimed at coarse, tightly curled hair textures. On the other hand, ammonium thioglycolate is often used in what are known as "no-lye" relaxers, which are milder and less damaging to the hair but still effective for chemical straightening.

Using these ingredients allows stylists to manage and alter the hair's natural shape effectively. Understanding the role of these chemicals is crucial for anyone working with hair services, as it helps to ensure safe and effective applications.
