I think I want to dye my hair, but can't afford a hairdressers or have the time so am thinking of doing it at home, My hair is a horrible dark mousey blond with a lovely grey streak in, I think it is too dark for my colouring so want to go lighter. Are there any good colours that won't leave it with a solid 'blocky' colour ? I am thinking more a caramel/dark blond so nothing to dramatic.
