i've always had really terrible dandruff, and im always looking for something to fix it. i've done apple cider vinegar rinses, black tar shampoo, head and shoulders and they work for a while and then stop working. i decided to try some of the pet shampoo my brother bought for his dog and it worked awesome! my scalp feels great! it says that its deep cleansing, removes scabs and crusts, antibacterial and antifungal. it's called vet solutions. here's one place you can get it. its pretty pricey but it worked. i've also used soap with banana extract in it with pretty good results.
