There are several reasons for one to experience scalp dryness with minoxidil. I always advise a full exam to determine the precise cause.
Common causes include: Irritant contact dermatitis, allergic contact dermatitis, seborrheic dermatitis as well as a coexisting scalp conditions (psoriasis, eczema) need to be ruled out. For many of my patients, use of oil based products along with anti-seborrheic shampoos containing ketoconazole or zinc pyrithione prove very helpful to treat the dryness.
