When performing a chemical relaxer service, what is the primary purpose of applying a protective base cream to the client's scalp and hairline?

  1. ATo prevent the relaxer from over-processing the hair strands.
  2. BTo ensure even distribution of the relaxer product.
  3. CTo create a barrier that protects the skin from chemical irritation.
  4. DTo condition the hair and add shine after the service.
Show answer & 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
  • Applied liberally, but carefully to avoid hair
  • Essential for client comfort and safety

Memory trick: Base cream is a 'Barrier' for the 'Burn' of relaxers.
