Food Coloring on hair?

Question

How long will it last, or will it come out in the shower?

I'm curious to know.

Answer 1

Why would you do that when you can go to any beauty supply store like sally's and get whatever color you want. all the wild crazy colors come in semi- permanents. They come out in just a few washes and you can change it again.Keep in mind Demi-permanent colors last a little bit longer.Good luck

Answer 2

i don't know about food coloring but i have pink hair and it's there to stay

  but before i used  a sharpie on really any color hair (even black) and it will stay till the next time you're hair gets wet
