A 9-month-old girl developed generalized hypertrichosis after being exposed to 5% topical minoxidil for 2 months through contact with her grandfather, who used the medication daily and held her on his shoulders for extended periods. Once minoxidil was removed from her environment, her hair distribution returned to normal within 4 months.
