Psoriasis and Rogaine

I have scalp psoriasis and consequent thinning patches. Would using Rogaine aggravate the psoriasis?

Rogaine (minoxidil) can cause skin irritation and may aggravate your psoriasis. You might try it and see. The worst case is that you make the psoriasis worse for a few days. Many people with psoriasis have to experiment on how to manage the disease. It behaves differently in different people.
