I dyed my hair, with what was supposed to be blonde, a couple of weeks ago and it turned out wrong. It would actually be 3 weeks on saturday and my roots are already coming through. The colour has come through as a horrible yellow colour and i was wondering if it would be safe to dye my hair a darker colour to cover it up? My Hair is down past my boobs too so would you think i'd need two boxes?
what coulour is your natural colour, are you wanting to dye it back to that or a different blonde? if your not sure I would ask a hairdresser what number colour to buy then do it yourself. Boots own brand are quite good but you might even need 3 boxes depending on the thickness of your hair. Getting the right shade of blonde is quite difficult especially if your naturally brown or dark brown haired.
