My hair is naturally black and I really want to change to a light brown, how can I do this from home?

What is your natural hair color? You can't dye your hair dark naturally that's not possible?

Try washing it a few weeks with fairy liquid, the chemicals help lift the colour, my hairdresser suggested it to me and it worked. I strongly recommend it, it may go a greeny colour at first but the result will be a browny colour. I could also suggest going to a hairdresser if this doesn't work, or try washing your hair with alcahol that might work.

Sorry, I only just realised you haven't added hair dye on it, these remedies will only qork to lift the hair dye colour, sorry about that, you may just have to bleach it. That's the only other way I can think of.
