What color is yr hair now?
Be forewarned -- If you currently have dark hair, then this will require TONS of bleaching, which will leave the hair brittle and less luxuriant. Also, in that case, it won't take long for the color to start looking weird, unless you use special color shampoos, which tend to be expensive. (All those "blonde" shampoos in hair salons -- THAT is who those are for. They aren't for actual blondes.)
... And, even if you go to all those extremes, you have the issue of what to do when yr roots grow out in yr natural color that contrasts with everything else.
If you are blonde, or at least have light brown hair, then, go for it! I don't see any reason why not.
If I were you, in this case, I'd buy one of those temporary dyes / sprays that they make for Halloween, and test it out first. Basically, just "try on" that hair color for a couple days, and see if you really like it before taking the plunge for real. (Make sure to wear black... lol)
