Has anyone used Uncolor? It supposed to remove temporary hair color. I haven't had good experiences with it. I tried this on a coworker who wanted to take out the red block in the back of her hair (temporary), and it didn't budge. Not even the Malibu 2000 moved it, and it usually does. I didn't want to go the lightner route, because she is always doing something crazy to her hair, and I was afraid of damage. We also don't have permanent color remover. Is the reason why Uncolor didn't take out the red at all because she had so much done to it already?
