What is the FIRST step during a retouch sodium hydroxide relaxer service?

The first step during a retouch sodium hydroxide relaxer service is to perform a scalp analysis. This is a crucial step because it allows the cosmetologist to assess the condition of the scalp and hair before applying any chemical treatments. During the scalp analysis, the stylist can identify any potential issues such as scalp irritation, cuts, or infections that could lead to adverse reactions when the relaxer is applied.

This assessment helps to ensure the client's safety and comfort throughout the process and enables the stylist to decide the best course of action for the service. It's important to understand the current state of the hair and scalp, as this will affect the effectiveness of the relaxer and the overall health of the hair.

After the scalp analysis, the stylist can then move on to other steps such as sectioning the hair, shampooing, and applying the relaxer, but starting with a thorough analysis is fundamental to a successful service.
