Which perm is best for clients who may be allergic to Thioglycolic acid?

• A. Acid perms
• B. Alkaline perms
• C. Exothermic perms
• D. Low/no Thio perms

Answer: (D)

When a client may be allergic to thioglycolic acid, the goal is to minimize exposure to thiol-based reducing agents. Low/no thio perms are designed to use alternative reducing agents or much less thioglycolate, reducing the risk of triggering an allergic reaction while still allowing the hair to reform its bonds. The other options don’t address the allergen: acid perms and alkaline perms typically rely on thioglycolate-based reducing agents, so they carry the same allergy risk; exothermic perms describe a heating reaction during processing and don’t inherently mean they’re safer for thioglycolic acid allergies.
