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

Temporary
Permanent
Semi-permanent
Demi-permanent

The correct answer is: Temporary

Temporary hair color does not require a patch test before application because it does not contain the same harsh chemicals found in other hair dyes. Permanent, semi-permanent, and demi-permanent hair colors all contain a developer and other chemicals that can cause an allergic reaction. Therefore, these options would require a patch test to ensure the product is safe and will not cause harm.
