I take it either you do hair or have a good friend who does......careful....I did mine hot pink once and it took YEARS to get it all out! lol
I had pink in my hair this summer and it came out easily and it was actual dye not the temporary one.
Whenever I change my hair I have my stylist that I go to when I come home, she is internationally known. I refuse to let anybody else cut or dye my hair. I keep up with retouching my roots when needed but she showed me how to do it corectly. Last time I got my hair done somewhere else, it got destroyed. And this girl knows exactly what I want all the time :P
