I used to have my natural mousy brown hair highlighted so it was a nice blonde,several months ago i dyed my hair medium brown with a semi permanent,as my hair is porous (sp) from the bleach highlights the brown is here to stay,i kind of like it but am thinking i'd like it highlighted again,is this ok? will the highlights show up? sorry,bit clueless about this kind of thing but trying to learn from past mistakes and research first so i've nothing to regret later!
