Which option correctly pairs a curl reform term with its description?

• A. Main ingredient in a curl rearranger — Ammonium Thioglycolate
• B. Curl Activator — main ingredient in curl rearranger
• C. Additional Booster — used during wrapping to saturate
• D. Rod Diameter — used to help retain moisture

Answer: (A)

Understanding curl reform terminology starts with the chemistry used to reshape hair. The main ingredient in a curl rearranger is Ammonium Thioglycolate, and its role is to act as the reducing agent that breaks the hair’s disulfide bonds so the strands can be re-formed into a new curl pattern. That direct chemical function is why this pairing is correct. Curl Activator isn’t the primary chemical in the rearranger—it’s typically a post-processing product used to help set or rehydrate the curl after reforming. An Additional Booster isn’t a standard label for the wrapping saturant, and Rod Diameter is a physical measure that affects curl size, not moisture retention.
