Hii I really need your help,my hair is a light brown and I died it a dark blonde but it didn't work I got told it was because I washed by hair the same day before I died I! Big oops! I didn't know ,but what I want to know is how long do I have to wait before I can dye again? Many thnaks xx

It shouldn't have had any effect on your hair dye just because you washed your hair before you dyed it. Some people routinely wash their hair to get the hair products out.

What do you mean by "it didn't work"? Is it too dark? Too light?

If you have to re-dye it, the main thing is that your hair is in really good condition before you color it.

Well basically I haven't noticed any diffrence tbh,people have said it looks lighter but not much diffrence x

You never end up with the color on the box (unless you're naturally blonde), so next time remember to pick a color that's a few shades lighter than you actually want.
