Other potassium channel openers, like diazoxide [39, 40] and pinacidil [41] can cause hypertrichosis in humans as well as minoxidil. In balding macaques minoxidil, cromakalin and P-1075 (a pinacidil analogue) stimulate hair growth in about 20 weeks of topical treatment, whereas a fourth potassium channel opener, called RP49356, is not effective [42].
The evidence that [potassium channel openers (PCOs)] are active on hair growth is correlative. In humans three PCOs have been reported to affect hair growth. Minoxidil was reported to induce hypertrichosis during early clinical trials as an antihypertensive [12]. These side effects were characterized by increasingly visual facial hair, thickening of eyebrows, and diffuse hair growth across the upper back and limbs. Systemic minoxidil induced hypertrichosis in 80–100% of adults [13]. Clinical trials using topical minoxidil demonstrate increased scalp hair in about 39% of treated balding men. Oral diazoxide causes hypertrichosis in most hypoglycemic children and about 1% of adults, and induces some scalp hair in 25% of the balding patients [13–15]. Systemic pinacidil induces hypertrichosis in 2–13% of patients [13]. We are not aware of any topical hair growth trials using pinacidil.
