blonde to ash brown

If u do, do it at home.Then don't use an ash color.Since u have some blonde in it.It could turn green where the blonde is.What skin tone do u have?I like warm tones better.Cuz ash colors tend to look dull.Trust me u would get bored with an ash color real fast.I'll be back to help.I don't wanna see u turn it to a gree color.

If u do color it yourself.I'd just foil it with blonde chunks.All U do is get the foil at Sally's, then get the bleach u like.It has directions on the box on how to foil it.Make sure u get the foil that has the board with it.The board is the thing u put on your hair to push against the head & then put the foil on it & use a highlighting brush to apply the bleach.Make sure u get someone that knows how to foil to show u how to do this first.I love foiling my hair.It looks natural.I use Basic White bleach.I hope I explained this ok.I'm better at showing, than telling how to do things.Good luck!

What color blonde hair?  Think of the color wheel.  If you add ash which is often blue to yellow hair, you'll get green hair.
