Where could I get blue or purple hair dye?
Very rarely, you can find that stuff in drugstores. My suggestion is Sally’s, but it can also be found at Hot Topic, usually. Sally’s Beauty Supply is definitely my suggestion. But, so you know, a lot of the time you have to bleach your hair first, and the dye WILL fade. Trust me, I had a head of faded-green hair color because I dyed my whole head turquoise. After following all the instructions to a T, my hair faded after a week. That’s mostly because they colored-dyes usually don’t have the same chemicals as, like, a box of Revlon or L’oreal stuff.
