Which statement is true regarding products that contain aniline derivatives?

• A. A skin patch test is required
• B. A skin patch test is not required
• C. Patch tests are only for eyelashes
• D. Patch tests are optional

Answer: (A)

Aniline derivatives can be allergenic for some people, so testing for sensitivity before using products that contain them is essential. A skin patch test helps reveal whether a client will react to the dye ingredients without applying the product to the scalp. The test places a small amount of the product under a patch on the skin for about 24 to 48 hours and watches for signs of a reaction, such as redness, itching, or swelling. If a reaction occurs, the product should not be used on the client, and an alternative should be chosen. This precaution protects clients from potential dermatitis or other adverse reactions, making it a required safety step.
