Question: 1 / 400

What is required before coloring a client's hair to ensure safety?

Applying a deep conditioner

Performing a patch test

Before coloring a client's hair, performing a patch test is essential for ensuring safety. A patch test involves applying a small amount of the hair color product to a discreet area of the client's skin, usually behind the ear or on the inner forearm, to check for any allergic reactions or sensitivities to the dye. This step is crucial because it helps identify potential allergic reactions that could occur with full application of the hair color, thereby protecting the client's health and preventing adverse effects.

While options such as applying a deep conditioner, providing a scalp massage, and conducting a full consultation are important practices in the overall hair treatment process, they do not specifically address the critical safety concern of allergic reactions to hair color. The patch test directly targets this issue, making it a necessary precaution before proceeding with any hair coloring service.
