I think I may have to go to the hairdressers rather than risk it. The only thing that worries me is that my roots show every 2-3 weeks so if I get it done at the hairdressers I will have to go back every few weeks and it ends up pricey! Or could I go lighter brown at the hairdressers then after that dye it myself each time it needs doing by using a light brown hair colour?
be warned, the bleach bath the hairdresser will use will be very harsh once done you can use a home dye in a lighter shade when you need it. I did the same from very dark brown to a mid brown, its still a bit darker than I wanted and a bit red from the bleach but would nevr do it again, it ruined my hair
