During that week before nearly all the color washed out, her daughter received a lot of compliments. She still has a little bit of purple left, but it looks like a few highlights, which are noticeable only if the light hits it right.
I have to agree that purple hair color doesn't stay in long. I think mine lasted a month, and that's because I only washed it once a week. (When my hair isn't specially colored, I wash it more often). It was sad seeing the color flow down into the shower drain.
