This report describes two cases of generalized hypertrichosis in children due to indirect exposure to topical minoxidil, a treatment for androgenetic alopecia. A 2-year-old and a 7-month-old, both otherwise healthy, developed excessive hair growth after skin contact with caregivers using minoxidil. The condition regressed significantly after preventing further exposure. The study highlights that children are more susceptible to this side effect due to factors like thinner skin and higher absorption rates. It emphasizes the need for detailed exposure histories in pediatric hypertrichosis cases and advises caregivers on preventing accidental exposure. Minoxidil-induced hypertrichosis in children is typically benign and reversible.
