ihave just used this dye for the first time today and i am amazed at how well it has worked. my hair has now been bleach blonde done by myself for three months now. my natural hair colour is very dark brown. so the journey to blonde was not an easy one. i have orignally been using 40 volume bleach to get my hair to lift how ever i have always been left with orange gingery patches that simply wudnt shift even after several bleaching sessions and using a toning shampoo. my roots were showen thro again and i didnt want to have to keeping using bleach to cover them as i kno over time this wud destroy my hair. seen this and bought it but i was very skeptical as i thought ill probably end up with yellow orange roots. however i have been proved wrong it has over my roots fab from dark brown to white so easy and there was no stinging/burning sensation that i previously got with the bleach. i am goin to buy another dye tomorro to use one the gingery midlengths n ends that wudnt lift before as sadly one bottle was only enough to cover my roots as the only downside is the mixture is very thick so u may need more than one box. overall fabulous dye left my hair in great condition. no dryness. excellent colour payoff no yellow or orange patches onlly downside being the mixture is quite thick so i recommend unscrewen the lid once uve shaken up the bottle then apply.
