The main ingredient found in a booster is:

The main ingredient found in a booster is a mild form of ammonium thioglycolate, which is used to enhance the effectiveness of perm solutions. Boosters, also referred to as perm boosters or accelerators, are designed to modify the pH level of the hair and help to break down the hair's natural structure, allowing for better curl formation. The ammonium thioglycolate works by softening the hair, enabling the bonds to be restructured when the perm solution is applied, resulting in a lasting and defined curl pattern.

On the other hand, ingredients like coconut oil are primarily used for moisturizing and conditioning hair rather than altering its structure for chemical processes. Sodium chloride can be involved in formulations for its stabilizing properties but does not play a significant role in the perming process itself. Calcium hydroxide, often used in some types of relaxers, does not relate directly to the action of boosters in perms. Hence, the presence of ammonium thioglycolate in the booster is what ensures its effectiveness in enhancing the perming procedure.
