Most Helpful Guy
i'm asian, and have dyed my hair all different colors. the time they give you is just an estimate, if its good dye you should leave it in till you get the color you want. I always had to bleach my hair blond before dying it and it always took longer than usually estimated. I've never used feria, but manic panic is a good semi-permanent dye. it usually lasts a few weeks, fades in the shower or will come out in a pool though.
