A client has coarse, resistant hair and desires to achieve a significant curl pattern with a permanent wave. Which type of perm solution would be most effective for this hair type?
- ATrue acid perm
- BAcid-balanced perm
- CExothermic perm
- DAlkaline perm
Show answer & explanationAnswer & explanation
Correct answer: D. Alkaline perm
Alkaline perms, also known as cold waves, have a high pH and are designed to process resistant hair types effectively at room temperature, creating a strong curl. Acid-balanced perms are for more delicate hair.
Why the other options are wrong
- A. True acid perms have a lower pH and require heat, and are typically for more delicate hair.
- B. Acid-balanced perms are for delicate or damaged hair, not resistant hair.
- C. Exothermic perms generate their own heat but are not specifically designed for resistant hair's chemical structure.
Alkaline Perms
Chemical texture service (permanent wave) with a high pH (9.0-9.6) that processes at room temperature without added heat, ideal for coarse, resistant hair.
- pH range: 9.0-9.6
- Main ingredient: Ammonium thioglycolate
- Processes at room temperature (cold wave)
- Creates a strong, firm curl pattern
- Suitable for coarse, resistant, or normal hair
Memory trick: Always consider 'A' for acid, 'A' for alkaline with perms.
