chemical used in hair perming to break disulfide bonds
Ammonium Thioglycolate, also known as "Thio" or "Perm Salt," is a chemical compound commonly used in hair perming and straightening treatments. It works by breaking the disulfide bonds in the hair's keratin structure, allowing the hair to be reshaped into curls or straightened. This process is reversible, meaning the hair can return to its natural state over time or with additional treatments.
