What should be done before applying a relaxer?

Performing a strand test before applying a relaxer is essential for several reasons. A strand test helps determine how the hair will react to the relaxer based on its current condition, which can include factors such as texture, porosity, and previous chemical treatments. This test allows the stylist to assess the hair's strength and elasticity, ensuring that it can withstand the chemical process without significant damage or breakage.

By evaluating a small section of hair with the relaxer, the stylist can predict how long the product should be left on and can make informed decisions about whether to proceed with the treatment on the entire head. Conducting a strand test also enhances the overall safety of the service, as it provides insight into whether the client's hair can handle the relaxer effectively.

While washing the hair and applying protective oil can be important steps in the prep process, they do not provide the specific information needed about the hair's reaction to the relaxer. Consulting the client is crucial for understanding their expectations and concerns, but it does not substitute for the technical assessment that a strand test provides. The strand test is a vital procedure in ensuring the health of the hair during chemical services.
