The choice regarding which type of tint mustaches and beards should never be colored with is correct because aniline derivative tints contain certain chemical compounds that can pose health risks, especially when applied to sensitive areas like the face. Aniline derivatives are often used in permanent hair dyes due to their ability to provide long-lasting color, but they can also cause allergic reactions or skin irritations, which are particularly concerning when used on facial hair where the skin is more delicate.

In contrast, the other types of tints listed have different formulations and safety profiles. Semi-permanent tints typically do not contain harsh chemicals and are milder, making them more suitable for use on facial hair. Herbal tints are derived from natural ingredients and are generally considered safe for use on the face. Non-aminated tints do not contain aniline derivatives, making them less likely to cause irritation or allergic reactions. Therefore, aniline derivative tints should be avoided for coloring mustaches and beards to ensure safety and minimize risks of adverse reactions.
