I have problems with my skin on my scalp. there are these hard and dry spots on my scalp.

Hard spots on scalp: Without a picture and exam hard to tell- could be seborrheic keratosis and plaques. Both conditions are benign and treatable.

VisualDX: Hi, it’s hard to say without a picture but there is a great app that may be able to help you get a diagnosis without being seen in person by a dermatologist. The app is called VisualDX and is one of the best, if not the best out there. Many clinicians, including myself, use it. Just snap a photo and it gives you a list of possible diagnoses. Good luck!
