Allergic to Hair ColorQ: I am allergic to hair color. How can I color my hair without using chemical products?
A: Are you allergic to all hair color, or just permanent hair color formulas? If you are only allergic to permanent colors, try the semi- and demi-permanent colors and even temporary colors. If you are unsure about the level of allergy (and if you don't know what ingredients you are allergic to) perform a patch test before using the product.
If it is all hair color, then you should look into natural and organic hair color products made using henna. Just be sure to read up on henna and the specifics of caring for henna-colored hair. Henna can give you a variety of color options, and are preferred by people who want to avoid chemical products.
