What is the primary ingredient in most hair relaxers?

The primary ingredient in most hair relaxers is sodium hydroxide. This chemical compound is a strong alkaline substance that effectively breaks down the disulfide bonds in the hair's protein structure, allowing for the straightening of curly or wavy hair textures. Sodium hydroxide works by opening the hair cuticle and softening the hair, enabling it to be reshaped into a straighter form.

Sodium hydroxide relaxers are particularly popular because they provide a durable and long-lasting straightening effect, making them a common choice for clients seeking permanent hair straightening solutions. The effectiveness of sodium hydroxide in altering hair texture is well-documented, and its ability to deliver significant results has solidified its status as a key ingredient in many relaxer formulations.
