A client with fine, limp hair desires a perm that will provide maximum body and curl, but also maintain the hair's integrity. Which type of perm solution would be most suitable to achieve these results?
- AAlkaline (cold) perm
- BAcid-balanced perm
- CExothermic perm
- DLow pH alkaline perm
Show answer & explanationAnswer & explanation
Correct answer: A. Alkaline (cold) perm
Alkaline (cold) perms are highly effective for creating strong, firm curls, especially on resistant, fine, or coarse hair. Their higher pH opens the cuticle more aggressively, allowing for deeper penetration and a more defined curl pattern, which is ideal for adding maximum body and curl.
Why the other options are wrong
- B. Acid-balanced perms are gentler and produce softer, looser curls, more suitable for fragile or damaged hair.
- C. Exothermic perms are a type of acid perm that self-heats, but still generally produce softer curls than alkaline perms.
- D. Low pH alkaline perms are a gentler form of alkaline perm, but still not as strong as a traditional alkaline perm for 'maximum' body and curl on fine hair.
Alkaline (Cold) Perms
Alkaline perms, also known as cold perms, use ammonium thioglycolate and have a pH between 9.0 and 9.6. They process without heat, creating strong, firm curls, and are best for resistant, normal, or coarse hair.
- High pH (9.0-9.6).
- Strongest curl formation.
- No external heat required.
- Good for resistant, normal, or coarse hair.
Memory trick: Alkaline gives 'all-out' curls, while 'acid' is for a gentler ride.
