Question: 1 / 400

What should a stylist do before a hair coloring treatment?

Wash the client's hair.

Perform a strand test.

Before a hair coloring treatment, performing a strand test is essential for several reasons. A strand test involves taking a small section of the client's hair and applying the color formula to it. This allows the stylist to assess how the hair will react to the dye, including the resulting color, the processing time, and the hair's overall health and condition. It also helps in identifying any allergic reactions to the chemicals in the dye, thus ensuring the client's safety.

Having this information beforehand is critical because hair can respond differently based on its previous treatments, texture, and porosity. This precaution helps the stylist make the necessary adjustments to avoid undesirable results and provides a preview of the final outcome, leading to a more satisfactory experience for the client.
