What is the first step in the hair coloring process?

Performing a patch test is essential as the first step in the hair coloring process because it is a necessary safety precaution. A patch test involves applying a small amount of the dye to a discrete area of the client’s skin, usually behind the ear or on the inner elbow, to check for any allergic reactions. This step is crucial since it helps to avoid potential adverse effects such as skin irritation or allergic reactions that could arise from the chemicals in the hair dye.

Choosing the right shade, consulting the client about their hairstyle, and applying the color are all important parts of the hair coloring process, but they should only take place after confirming that the client does not have an allergic reaction to the product. This ensures the safety and comfort of the client and is why a patch test comes first.
