Performing a patch test with hair color is primarily done to check for allergic reactions. This procedure involves applying a small amount of the hair dye to a discreet area of the skin, typically behind the ear or on the inner arm, and observing the area over a specified period, usually 24 to 48 hours. The goal is to determine if the individual has an adverse reaction to any of the ingredients in the dye, which could range from mild irritation to a severe allergic response.

Sensitivity to hair dye can occur, and reactions may not happen with the first use; prior history of reactions to other cosmetic products can also be a factor. Conducting a patch test is a crucial step to ensure the safety of the client and to prevent potential health risks associated with hair coloring.

While determining the right shade and testing the product's strength are essential aspects of a successful hair coloring procedure, they do not address health and safety concerns. Additionally, the concern about how the color may fade over time pertains to the quality of the dye but is not directly related to the immediate health effects of the product on the skin. Thus, the primary reason for conducting a patch test centers on safeguarding against allergic reactions.
