How to make hair dye on your own?
I'm not sure how you'd make real hair dye, but you could always mix conditioner and kool-aid or something. Not exactly the same thing as real hair dye but that's the closest I can think of
food coloring and conditioner
check YouTube they have tons of different ideas.................
Some people say cool aid, but beware my friend has brown hair and did red cool aid and after a year the color still won't go away!
