A client with resistant, coarse hair desires a permanent wave that will provide a strong, firm curl. Which type of perm solution is generally most suitable for achieving this result?
- AAlkaline perm
- BLow pH perm
- CExothermic perm
- DAcid-balanced perm
Show answer & explanationAnswer & explanation
Correct answer: A. Alkaline perm
Alkaline perms, also known as cold perms, have a pH between 9.0 and 9.6, making them suitable for resistant hair types and creating a strong, firm curl. They process without heat.
Why the other options are wrong
- B. Low pH perms are typically acid perms, which are not strong enough for resistant hair.
- C. Exothermic perms generate their own heat but can be either alkaline or acid-balanced in their chemical composition; the question asks about the solution type for resistant hair.
- D. Acid-balanced perms are for porous or delicate hair and produce softer curls.
Alkaline Perms
Permanent waves that use ammonium thioglycolate and have a high pH (typically 9.0-9.6) to process hair, suitable for resistant hair.
- Process without heat (cold perms)
- Produce strong, firm curls
- Not recommended for porous or damaged hair
Memory trick: Alkaline for 'A' strong curl, like 'A'thletes need strength.
