Will Using Minoxidil Make My Scalp Oily?

Minoxidil itself is not known to make the scalp oily, but it does come in a liquid form that can sometimes leave a slight residue if not fully absorbed. The foam version of minoxidil is less likely to leave an oily feeling. If you notice your scalp becoming oily, it might be due to your scalp’s natural response or other hair care products you’re using in combination with minoxidil.
