Hair color isn't always about just "color". It's about shades, hues, and a good cut that will show off your new color. Perfect color doesn't come in a bottle. If you are hoping to get a color correction for past mistakes (caused either by you or another salon), it will take a real expert to add in the right toners to counter the faulty shades you are trying to get rid of.
Some of the most interesting hair color ideas, however, do not come from professionals but from celebrities who sport unique looks to stand out in a crowd. Not only do they manage to start off a fad, they also help create some very interesting hair color ideas. So if you have a favorite movie star you associate yourself with, you can always check out the hair colors they have sported now and in the past. Try not to choose a hair color idea which does not suit your personality as that is something you will be very uncomfortable in once you get it done!
