To apply scalp psoriasis medication:
- Put petroleum jelly on cotton balls and put them into your ears to keep medications out.
- Use medications sparingly. They may cause skin irritation and can weaken hair shafts, causing temporary hair loss.
- With an oil or lotion, part your hair and drip the medication onto your scalp.
- With a cream or ointment, rub it right into your scalp.
- Covering your scalp with a shower cap for a short period of time may help some medications work better, but check with your doctor first.
