- AShampoo the hair thoroughly.
- BPerform a strand test.
- CApply a protective base cream.
- DApply a protein conditioner.
Show answer & explanationAnswer & explanation
Correct answer: C. Apply a protective base cream.
A protective base cream is essential before applying sodium hydroxide relaxers to shield the scalp and skin from the highly alkaline chemicals, preventing irritation and burns.
Why the other options are wrong
- A. Hair should generally not be shampooed immediately before a relaxer, as this can stimulate the scalp and make it more sensitive to the chemicals.
- B. A strand test determines processing time and desired results, not scalp protection.
- D. A protein conditioner might be used post-relaxer, but not as a primary scalp protectant before application.
Protective Base Cream
A creamy substance applied to the scalp and hairline before a chemical relaxer to protect the skin from irritation and burns caused by the alkaline chemicals.
- Creates a barrier on the skin
- Applied to scalp, hairline, and ears
- Essential for sodium hydroxide relaxers
- Prevents chemical burns and irritation
Memory trick: Protect the SCALP like a SHIELD before relaxing.
