My husband has a rash on his head that looks like psoriasis what is the treatment for this please (it's been bleeding) thank you?

Rash on head: There are several conditions that can cause a rash or skin peeling on the head. If it is localized over a specific area it could be due to psoriasis. If it is associated with hair loss it could be due to fungus. If it is widespread it could be due to seborrheic dermatitis. It is useful to use shampoos such as head and shoulders, Nizoral (ketoconazole) and tar shampoos. Topical steroids can also help. See MD

OTC and/or exam: He might try OTC shampoos after asking a pharmacist for suggestions. Since it's already in bad shape, a visit to his Dr may be the best thing to avoid infection, etc. It may be very worth the visit in terms of relief and overall health. Best!

See doctor: Rashes or skin lesions that bleed can signal skin cancer, so it's best to see a dermatologist fro diagnosis and treatment.

First try to avoid..: Try to avoid scratching. Gently clean with warm water and antibacterial soap and apply thin layer of hydrocortisone ointment 1% available over counter. Cover with non stick bandage. Schedule appointment with dermatologist. This could be several things, so best to let the expert evaluate it and if needed, do a biopsy of it.
