Which perm is best suited for a client who may have allergic reactions to Thioglycolic acid?

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

Answer: (D)

When a client may have an allergic reaction to thioglycolic acid, the goal is to minimize or eliminate exposure to thioglycolate in the perm solution. Low/no-Thio perms are designed to do just that: they use little or no thioglycolic acid and rely on alternative reducing agents or reduced thio content, reducing the chance of triggering an allergy. This makes them the safest choice for someone with a suspected thioglycolic acid sensitivity. Always patch-test and carefully check ingredient lists, because formulations can vary by brand. Other perm types typically rely on thioglycolate-based reducing agents, which keeps a higher risk for someone with this allergy.
