A client with fine, delicate hair desires a permanent wave. The cosmetologist wants to minimize damage while achieving a soft, natural-looking curl. Which type of perm solution is generally considered the gentlest and most suitable for this hair type?
- AAlkaline (cold) perm
- BExothermic perm
- CLye-based perm
- DAcid-balanced perm
Show answer & explanationAnswer & explanation
Correct answer: D. Acid-balanced perm
Acid-balanced perms, often containing glyceryl monothioglycolate (GMTG) and having a lower pH (4.5-7.0), are gentler on the hair. They are ideal for fine, delicate, or previously damaged hair, producing softer curls with less swelling and damage compared to highly alkaline perms.
Why the other options are wrong
- A. Alkaline perms are strong and can be too harsh for fine, delicate hair, leading to potential damage and an overly tight curl.
- B. Exothermic perms generate their own heat and are often strong, which can be too aggressive for fragile hair, increasing the risk of damage.
- C. Lye-based perms (sodium hydroxide) are relaxers, not permanent waves, and are far too strong for permanent waving, especially on fine, delicate hair.
Acid-Balanced Perms
Permanent wave solutions with a pH between 4.5 and 7.0, often containing glyceryl monothioglycolate (GMTG). They are gentler, cause less hair swelling, and are ideal for delicate, fine, or color-treated hair.
- pH 4.5-7.0 (acidic or neutral).
- Gentler action, less swelling.
- Produces soft, natural curls.
- Best for fine, delicate, or color-treated hair.
