To reduce dandruff/get rid of it, crush two aspirin tablets and mix them with one serving of shampoo. Apply the mixture to your hair and leave it for about two minutes, so it can settle on your scalp. Rinse the mixture off then shampoo your hair once more. After the final rinse, the flakes are either gone or lessened. Its amazing and really works!
I checked dandruff in the memories and didnt see this, so feel free to flog me if its already there :D
