This is what happens when you don't pay attention. All of a sudden you are closing in on 30 and you haven't accomplished shit.....all at one fail swoop if comes crashing down. Guess the only way to do anything about it is start today, make it diffrent, I should go kick someone in the balls or a good ambushed smackdown outta make me forget this little reality check. 
Maybe it's the type of color you're using. I use Color Fiend's Turq Tsunami and Paint Box's Blue Velvet. I wish I had better advice for you. I really don't know much about hair, just that I like to get mine done!
