A client has extremely fine, fragile hair and desires a permanent wave that will add body and soft, loose curls without causing excessive damage. Which type of perm solution would be most appropriate for this client's hair type and desired outcome?
- AExothermic Perm
- BTrue Acid Perm
- CAlkaline (Cold) Perm
- DAcid-Balanced Perm
Show answer & explanationAnswer & explanation
Correct answer: D. Acid-Balanced Perm
Acid-balanced perms have a pH between 4.5 and 7.0, making them gentle enough for fragile, fine, or color-treated hair. They produce soft, natural-looking curls and minimize damage.
Why the other options are wrong
- A. Exothermic perms generate their own heat and can be too strong and damaging for fragile hair, similar to alkaline perms.
- B. True acid perms (pH 4.5-7.0) also produce soft curls and are gentle; however, they require external heat and have slower processing times, making acid-balanced perms (which are often room temperature or self-heating) a more typically appropriate choice for body and soft curls on fragile hair in a salon setting.
- C. Alkaline perms (pH 9.0-9.6) are strong and can be too harsh for fine, fragile hair, potentially causing damage and over-processing.
Acid-Balanced Perms
Permanent waves with a pH between 4.5 and 7.0, formulated for delicate, fine, or color-treated hair to create soft, natural curls with minimal damage.
- Gentle on fragile hair.
- Produces soft, natural-looking curls.
- Often processes at room temperature or with minimal heat.
Memory trick: Fragile hair needs a gentle kiss, so acid-balanced is the perm bliss.
