I rarely have a natural hair color. I had to dye my hair brown a couple weeks ago, because I promised my dad I'd go natural for his wedding. I plan on dying it again a while after. I haven't gotten a 'freak' comment since high school, haha, because I don't hang around people who care about s.hit like that, nor would I feel self conscious if someone said anything like that. I don't care what they think. If people think it's weird, they keep it to themselves, and I get tons of compliments on my hair colors.
I love this look! I know loads of girls going for the dark pink/red color atm. I have afro hair in braids so I can't do this but I have always liked putting a colored ribbon in my hair like a streak of color.
I love crazy colored hair! it looks amazing! Though I wouldn't dye my hair, mainly because as much as I may love colors I prefer my natural hair and because of how much the dye damages my hair :(. I wouldn't be worried about being called a freak, I mean colorful hair causes an "eye candy"/eye-catching effect, but nowadays many people have colorful hair, or at least they do where I live :P
I used to have red/purple hair but now I find outlandishly colored hair really tacky and I will only stick to my natural color, I'm not worried about looking like a freak I'm worried about looking gross by my standards.
