Which active ingredient in a relaxer is known for managing curly hair?

The active ingredient known for managing curly hair in a relaxer is ammonium thioglycolate. This chemical works by breaking down the disulfide bonds in the hair's cortex, which allows the hair to be reshaped and effectively straightened. When applied, ammonium thioglycolate softens the hair's structure, making it easier to smooth out curls and waves.

This ingredient is commonly found in "thio relaxers," which are particularly effective for those with curly, wavy, or frizzy hair textures. The formulation of ammonium thioglycolate is milder than some other typical relaxers, making it popular for clients who seek a straighter look without excessive damage.

In contrast, while the other ingredients mentioned can also be used in relaxers, they serve different purposes or have different applications in hair texture management. Sodium hydroxide, for example, is known as a strong alkaline relaxer that is effective but can be harsh on the hair if not used correctly. Calcium hydroxide, often found in no-lye relaxers, also alters the hair's structure but may not be as effective for every hair type compared to ammonium thioglycolate. Guanidine carbonate is associated with creating a milder
