- AAcid-balanced perm
- BCold wave
- CExothermic perm
- DAlkaline perm
Show answer & explanationAnswer & explanation
Correct answer: A. Acid-balanced perm
Acid-balanced perms, often referred to as true acid perms, have a pH between 4.5 and 7.0 and are recommended for delicate or color-treated hair as they cause less swelling and damage.
Why the other options are wrong
- B. Cold waves are alkaline perms that process at room temperature, making them too strong for fine, delicate hair.
- C. Exothermic perms are alkaline perms that create their own heat, making them stronger and potentially more damaging for fine hair.
- D. Alkaline perms are stronger and have a higher pH, suitable for resistant hair, not fine or delicate hair.

- Lower pH (4.5-7.0)
- Gentler action, less swelling
- Recommended for delicate, damaged, or color-treated hair
- Often require external heat for processing
Memory trick: Acid-Balanced is for 'A'll 'D'elicate hair.
