I knew about Apple Cider Vinegar Pure from youtube. I watched different videos about this and understood it as remedy for dandruff. I suffering dandruff problems from many years and used different shampoos but never got a satisfactory result. Then I used apple vinegar diluted with water and tea tree oil on my scalp. I am using this twice in a week. Now I got a great relief from the problem. I didn't get a complete relief but I am comfortable and still continuing it.
