well, ive used shampoo every day for most of my life and since i started using it only 2-3 times a week my hair got much better. however, ive been facing some problems when it comes to dandruff, that little white "grains" in your hair. so, how can i have less dandruff while not using shampoo? also, what kind of shampoo and conditioner is better? btw my hair is 2a
