I've had dandruff since the 7th grade (I'm 19 now) and I can't stop scratching my scalp. Idk why I do it, but atleast I'm not the only one who does it. I'll be laying down scratching, trying to get those flakes that feel like sand off my scalp. However, doing that causes my hair to get oily and dirty. I kno I should stop but I can't help it! Also, I tend to ruffle my hair, usually in the bathroom cuz the tile is dark, and watch the flakes fall like snow
