What is the first step in performing a chemical relaxer?

1. A patch test

2. A strand test

3. A heat test

4. An evaluation of hair condition

The correct answer is: A strand test

The first step in performing a chemical relaxer is conducting a patch test. This test is essential to check for any potential allergic reactions to the chemical ingredients in the relaxer. By applying a small amount of the product to a discreet area of the skin, usually behind the ear or on the inner elbow, you can determine if the client has any sensitivity or allergy to the chemicals that might cause irritation during the chemical relaxing process. While evaluating the hair condition and performing a strand test are important steps in the overall process, they are typically done after establishing that the client does not have an adverse reaction to the relaxer. Evaluating hair condition helps to assess the texture, porosity, and overall health of the hair, which is crucial for deciding the appropriate relaxer strength. A strand test, on the other hand, is used to see how the hair will respond to the relaxer and to determine the processing time needed for the specific hair type. However, these can only be conducted safely if the patch test has been completed and confirmed to be non-reactive.
