Hi

My long hair is dark brown at the moment, dye on dye, covering greys and roots for years. I have just bought a much lighter dye, in the hope of lightening mine. It says if your hair is dark brown/ black, it should go chestnutish (but that probably means naturally dark brown/ black). I am hoping for a mid brown. I notice it has 20% vol peroxide in it. Do you think it will turn out ok? If so, what is the best way to apply it. leave the scalp till the end?

Thanks
