Florida Cosmetology Licensing ExamHair ServicesHard
A client with fine, brittle hair and a sensitive scalp requests a chemical texture service to add soft waves. The cosmetologist notes that the client has previously reacted poorly to strong chemical treatments. Which of the following chemical texture services would be the safest and most appropriate choice for this client?
- AExothermic perm with a high pH.
- BThio-free perm with Cysteamine Hydrochloride.
- CAlkaline perm with ammonium thioglycolate.
- DHydroxide relaxer with Lye (Sodium Hydroxide).
Show answer & explanationAnswer & explanation
Correct answer: B. Thio-free perm with Cysteamine Hydrochloride.
Thio-free perms, often using Cysteamine Hydrochloride as the active ingredient, are significantly gentler than traditional alkaline or acid perms. They have a lower pH and are less irritating to sensitive scalps, making them ideal for fine, brittle hair and clients with chemical sensitivities. They produce softer, more natural waves.
Why the other options are wrong
- A. Exothermic perms can be very strong and often have a high pH, making them unsuitable for sensitive scalps and fine, brittle hair, similar to alkaline perms.
- C. Alkaline perms are strong, high pH, and contain ammonium thioglycolate, which is too harsh for fine, brittle hair and sensitive scalps.
- D. Hydroxide relaxers, especially with Lye, are extremely strong chemical straighteners, not suitable for adding soft waves and highly damaging to fine, brittle hair and sensitive scalps.
Thio-Free Perms
A type of permanent wave that uses a reducing agent other than ammonium thioglycolate, such as Cysteamine Hydrochloride, to create softer, often more natural-looking waves with less irritation and damage.
- Gentler than traditional thio perms.
- Ideal for sensitive scalps and fragile hair.
- Produces soft, natural waves.
- Active ingredient often Cysteamine Hydrochloride.
Memory trick: For hair so fine, and scalp so shy, a 'thio-free' wave is the gentle reply.
