Question: 1 / 400

Why is it important to conduct a patch test when using hair dye?

To check for allergic reactions

Conducting a patch test when using hair dye is crucial to check for allergic reactions. Hair dyes contain various chemicals that can cause skin sensitivities or allergic responses in some individuals. By applying a small amount of the dye to a discreet area of the skin, usually behind the ear or on the inner elbow, the stylist can monitor for any signs of irritation, redness, or itching within a specified period, typically 48 hours. This precaution helps ensure the safety of the client, preventing potentially severe reactions that could arise from full application.

Other considerations, such as assessing color results, product scent, or application time, are important for the overall hair coloring process but do not directly relate to the immediate health and safety aspect that a patch test addresses.
