What are the two types of chemical relaxers?

• A. Sodium Hydroxide And Thio
• B. Sodium Hydroxide
• C. Thio (Ammonium Thioglycolate)
• D. Ammonium Sulfide

Answer: (A)

Chemical relaxers work by breaking the disulfide bonds in hair to straighten it, and they fall into two main families: hydroxide-based relaxers and thioglycolate-based relaxers. The hydroxide family uses strong bases, such as sodium hydroxide, to relax the hair. The thioglycolate family uses ammonium thioglycolate to achieve the same result through a different chemical mechanism. Ammonium sulfide isn’t a standard category for professional relaxers, so the two primary types are sodium hydroxide-based and thioglycolate-based relaxers.
