I’ve been using minoxidil and finasteride PG-free solution for about a week, visited the barbershop for a haircut, and woke up the next morning with forehead redness resembling an impending acne breakout. I’ve applied aloe vera gel for the past two days, but it doesn’t seem to be helping. Any advice?
You could be reacting to an ingredient, even in a PG-free formula. Consider trying ketoconazole shampoo to reduce irritation and check for any unrelated skin issue. If the redness persists, it might be worth trying a different formulation or exploring topical CBD with MCT oil to help soothe the area.
