I want to grow out my high lights and colour over them as close to my natural light brownish colour as possible. Can I do this without damaging my hair further? I've used semi-permanent before but it washes out so quickly.

I'm poor so going to the salon is not really possible but if I had to I would do it.

Does anyone know of any brand of colour that would suit what I want to do?
Fat does not make you fat. It's actually pretty important.
