People have been coloring their hair for a long time and especially in recent years, when dyes are not so toxic. And now you don't have to, for safety's sake, go to a wig to have blue hair. Just ask pop artists Katy Perry or Nikki Minaj, the latter in the photo here trying a blend of blond and blue. In fact mixing colors is really big now. This site shows hot colors for hair color for 2012 are bold, vibrant shades like purple, blue, red and green and mixing them with the brown, black, and blonde hair.

But one shocking color, which for the life of me I cannot understand, is gray. Believe it or not, it's one of the hottest hair color fashion trends as women are adding "gray lights" to their hair. Heck, I've been doing that naturally for the last few years. I'm hip and didn't even know it! At any rate, hair color and style will continue to be based on whatever singer or actor is popular, as people tend to mimic those in the spotlight.
