Red, Dry Patch on Scalp

I have a really dry patch on skin on my head and now it is really red. It is about the size of a penny. What could this be????

It could be one of a dozen potential things, such as ringworm, psoriasis, dermatitis, infection, etc….

I hope you get the picture. Without at least a photo, I couldn’t begin to even guess. The internet is fun, educational and a great communicating tool, but it is not a place to get your medical care. You should see a dermatologist for your skin issue.
