I'm a long time henna lover. Having two gray/white areas that just won't settle into a nice shade with repeated hennas I always have to do some indigo touchup. Amla added to my henna mix never calmed the areas either. Since indigo is kind of forever I'm thinking of switching to buxus. Anyone out there ever made that transition? Indigo gives beautiful colors mixed with henna - does buxus also remove orangy tones? I know buxus only lasts three weeks or so but I do my roots about that often anyway.

Any insite from experienced henna/indigo/buxus users would be appreciated. I know the strand test deal, but at this point there is no way I'm growing out a gray/white piece, henna-ing it orange, and then doing a bunch of strand tests on it. Thank you in advance for the help.
