With dandruff, you’ll see large, greasy flakes fall onto your shoulders, and your scalp could be red and itchy. It can be treated with either an anti-dandruff or prescription-strength shampoo.
Dry scalp, on the other hand, includes powdery flakes when you brush or wash your hair, and your scalp might feel tight. It can be a result of anything from product buildup to an underlying health issue. Many people find relief by using conditioning treatments that focus on the scalp.
It’s important to not use anti-dandruff shampoo on a dry scalp, as it can dry out the scalp further.
