Oops Hair Color Remover

My natural hair color is blonde and I dyed black. my roots are already back to normal, but I can not wait any longer. I was wondering if I bought color oops hair bleach and left on longer than 20 minutes, he manages to use What's worst that could happen?

I suggest you go to a professional. My sister was a blonde and black hair are dead. Wow, it took several years to recover to individuals using the products for the home. He looked at Orange, blond, red, brown, etc. It may be well worth the money that this is done in a salon.
