손게다슈
저는 우선 샴푸를 좋은걸로 바꾸는게 젤 좋더라구요
My scalp seems to be in a bit of a bad state. How should I take care of it? I've tried letting my shampoo sit for about two minutes a few times, but I don't see any noticeable difference. The dermatologist just told me not to wash my hair too often, and I really don't know what to do to manage it. It's extremely dry.
