What type of hair color can you use on vaginal?

Actually you can use any color you want to use. That hair is just like the hair on your head, but to achieve the color you want you may have to bleach (strip the color) it first just like your regular hair then color it. Just be careful not to get the chemicals in the wrong place and don't leave them on to long. It can be a perminate or semi perminate color have fun.
