I Have A Mild Scalp Rash Noticed By My Barber.

I have a mild scalp rash noticed by my barber. I have had it for 3 weeks now. My GP thought that it might be seborreah and said to shampoo with Nizoral but mild redness persists. No pain, no itching, and I did not know that I had it. I take 1 medication TWYNSTA (Telmisartan, an ARB) for HBP and very occasionally an Ativan for sleep (LORAZEPAM), and a few vitamins.
