When performing a chemical relaxer service, what is the primary purpose of applying a protective base cream to the client's scalp and hairline?
- ATo prevent the relaxer from over-processing the hair strands.
- BTo ensure even distribution of the relaxer product.
- CTo create a barrier that protects the skin from chemical irritation.
- DTo condition the hair and add shine after the service.
Show answer & explanationAnswer & explanation
Correct answer: C. To create a barrier that protects the skin from chemical irritation.
The protective base cream (or petroleum jelly) is applied before a chemical relaxer to create a protective barrier on the scalp and hairline, preventing direct contact of the strong alkaline relaxer with the skin and minimizing irritation or burns.
Why the other options are wrong
- A. The base cream is for skin protection, not for controlling hair processing time.
- B. Even distribution is achieved by proper application technique, not by the base cream itself.
- D. Conditioning and shine are post-service benefits, not the role of a pre-application base cream.
Relaxer Protective Base
A protective base cream is applied to the scalp and hairline before a chemical relaxer to shield the skin from irritation and burns.
- Typically petroleum-based

- Essential for client comfort and safety
Memory trick: Base cream is a 'Barrier' for the 'Burn' of relaxers.
