My hair already has highlights and color in it, by my roots are starting to show. I was wondering if I could buy my own hair dye, dye it all one color myself (really really dark brown is what I'm going for - and my natural color is kind of a dark brown) - do it with a friend's help, and THEN go to the hair stylist to have her highlight it with really blonde highlights. My hair already pretty much has this style now but I just want the whole thing redone again because as I said, the roots are showing. Would this work? Someone on another post said that trying to dye my hair all one color wouldn't work because the highlighted pieces would show through and look "muddy" as they put it...it's like trying to put a layer of paint over a color that is likely to show through. But don't you think that that wouldn't matter that much to me? I am going to highlight it anyway, so having a few pieces of previous color show through wouldn't bother me, right? Because then when I go and have highlights put in, it will all be a mixture of highlight colors in my dark hair and look pretty cool I would think. What's your opinions?
