yes it is!! i went from completely grown out GREY to vibrant brunette. yes its $$, but for a DIY home color product??? can't be beat.
i am going to try to gloss in about 3-4 weeks (i'll have roots showing by then as my damn hair still grows super fast) and see how that goes. have not tried the root touch up yet...my hair doesn't really HAVE a visible part much, its sort of a thick curly mass so roots aren't exposed much.
i'd rather not show before and after pics here, but if you PM me we can trade emails and i can send you the link for $15 off.....
