Henna over salon colored hair
I'm a real henna virgin here and this may have been covered before however I have a couple questions. (1) Can I do henna over hair processed with permanent color? My hair is currently an auburn shade. (2) My natural hair color at this point WAS a medium brown but is now more than 50% so I wonder how henna will do over that and (3) Am I better off trying to do this at home or finding a salon that does henna treatments? I don't recall ever seeing henna as being listed as something most salons do however. I have extremely thick botticelli curls and am currently using the DevaCurl three step program for cleansing and conditioning.
