Final answer:
Temporary hair color does not require a patch or predisposition test, unlike oxidative, permanent, and demi-permanent hair colors.
Step-by-step explanation:
The hair color that does not require a patch or predisposition test is temporary hair color.
Temporary hair color is a type of hair dye that coats the outside of the hair shaft and does not penetrate the hair cuticle. It usually lasts for a few washes and does not require any chemical reactions like oxidation or coupling. This means it is less likely to cause allergic reactions and does not require a patch or predisposition test.
On the other hand, oxidative, permanent, and demi-permanent hair colors all involve chemical reactions and require a patch or predisposition test to check for any potential allergic reactions before applying the color.
