boy I know how you feel, I have horrible dandruff also. I've been on my 7th day of colonix and notice my dandruff is mildly improving also my razor bumps, I still feel I need more time on the program to get full results, but on the 4th day I definetly noticed a difference usually when I wash my hair it's itchy and feels really tight, but on the 4th day of colonix no itches and very little dandruff. I also have the same head odor problems, that has also mildly improved too. I will post another message after three weeks on colonix.
