How is the hair typically prepared before applying a chemical relaxer?

Before applying a chemical relaxer, the hair is typically prepared by applying a protective cream. This step is essential as it creates a barrier between the hair and the scalp, helping to prevent irritation and potential burns from the chemical solution. The protective cream is often applied along the hairline and any sensitive areas. This precaution is particularly important given that relaxers contain strong chemicals designed to break down the structure of the hair to soften and straighten it. Proper preparation can help ensure the safety and comfort of the client during the chemical process, contributing to a successful and effective treatment.

While drying the hair thoroughly, cutting it to a shorter length, or curling it with heated tools may be relevant in various styling or treatment contexts, they do not specifically address the necessary precautions needed before a chemical relaxer application, which prioritizes protecting the scalp and the integrity of the hair.
