Can minoxidil lotion make an oily scalp worse?
Minoxidil is approved for use in males and females with androgenetic alopecia. A variety of different products are available including the minoxidil solution/lotion and minoxidil foam. The minoxidil foam is particularly popular because it is less greasy. There is no evidence that one product is superior to another so it's completely left up to personal preference and cost.
Individuals with oily scalps may bind the minoxidil foam preferably to the lotion. However, one must consider that the underlying oiliness could be due to seborrheic dermatitis and treatment of the seborrheic dermatitis may be necessary in such situations. Use of shampoos with ingredients such as ketoconazole, zinc pyrithione, ciclopirox and selenium sulphide can help to reduce oils. Appropriate treatment may allow the patient to use minoxidil lotion or foam - whichever they prefer.
