How to dye my hair pink
How I did it: I have very dark hair naturally, so i had to bleach the hell out of it first, which went fine with a friend's help. I went dinner with orangish hair once, it was great. Then I had a friend help me with the pink too and it was knotty and gross, but turned out fine once it was all in.
I LOVED having pink hair, and would do it again in a heartbeat. The only downside was when I was ready to go back to my natural color three months later and EVERYthing had a red undertone, but it still looked good.
Resources: Pink dye I ordered offline from funkyshop.com. It worked really well.
