Lemon juice and hair

Hi there! i read that lemon juice can be used to lighten the color of hair ( black for me ). Will lemon juice spoil my scalp or hair? the thought of something highly acidic....

I can't say it any better than Angl96 did!  Lemon juice would be horrible for your dark hair.

I apply peroxide (plain old peroxide in the brown bottle) to my root area and selected pieces of hair for highlights. My hair is brown originally, lightened to a dark blonde. I really didn't like how the color turned out, so eventually, I'm going to to go back to brown. But, in the meantime, I use peroxide to match my roots to the rest of my hair. I think it does a good job. I guess it can be damaging over time. I just do a few applications. Contrary to popular demand, it doesn't turn my brown hair orange, though I don't know what it would do to black hair. You can sit in the sun to maximize the effect, though I've gotten to the color I want w/o sun. My hair gets remarkedly lighter just being outdoors in warm weather, so I think I'm going to see what it does to my color before I go back to brown. There is a bit of brassiness overall, but I've been covering that up with a temporary dye (Fancifull). Also, some people on another hair board I visit mix a little honey with their conditioner. Honey is a humectant, a good moisturizer, and it lightens hair - some have seen results in a couple of weeks.
