well, i died my hair a blackish brown washout about 5 weeks ago or something like that, i left it in for ages so it wass pretty much black, and i want to make it last as long as possible . (i wash it less often , but not washing it at all is disgusting , so dont suggest it 
, so is there any way i can keep the colour in for alot longer? , (the reason i dont get permanent , is that it damages my hair, and i dont want regrowth)
thanks greatly
