Barber Practice State Board Practice Exam

The hair color that does not require a patch test before application is ___________ hair color.

1. Semipermanent

2. Permanent

3. Temporary

4. Oxidative

The correct answer is: Temporary

Temporary hair color is the type that does not require a patch test before application. This is primarily because temporary hair color products typically do not contain harsh chemicals or dyes that penetrate the hair shaft. Instead, they create a coating on the surface of the hair, which is designed to wash out after a few shampoos. Since temporary colors are usually made with non-reactive ingredients and are less likely to cause an allergic reaction, the necessity for a patch test is often bypassed. In contrast, other types of hair color, such as semipermanent, permanent, and oxidative colors, usually contain stronger ingredients that can provoke sensitivities, thus necessitating a patch test to ensure safety and prevent adverse reactions.
