lkadjfaklsj love this thread already.
My hair has been black (natural), streaked with blonde, partially blue, greenish, purple, but now it's all brown.
Pictures! I don't have pictures of when I had purple, or when I had blonde streaks.
Blue/greenish (from the blue fading)
For the funky colours (green, blue and purple) I had my hair bleached at a salon, and then added the other dye at home with the help of family/friends. Streaks were also from the salon.
The most current (brown) was also done at a salon. My hair is actually very very dark, so it's difficult to dye I guess. Well, it takes a long time, lol. I don't want it to come out blotchy, so I prefer paying and getting it done by someone.
