Now, I dye my hair but years ago I had dark brown hair and I used to do highlights. I'll tell you what looks fabuolous on dark hair.
Do several thin strands of golden blond. ALOT. Thick strands look awful and non-professional. Do it at a salon not by yourself.
Don't go for chestnutty or dark shades like that because it will never show with your dark hair. Go brighter and don't worry, it looks fantastic.
