Over highlighted blonde but want to be brunette!

[Uhohmummy]

I've been highlighting/balyage-ing my hair for as long as I can remember but my natural hair colour is very much mouse. I would really like to try go a rich, chocolatey brown. Is this possible? Has anyone done this successfully? If so, how?

Yes,easy peasy just ask your hair dresser. I did it a few years ago.

Yes of course but don't try to do it at home. Go to a hairdresser who knows what they're doing. If they're not careful, dark colour on top of blonde can go a bit green, but even this is fixable.
