Hair 4U F is a prescription topical solution made by Glenmark Pharmaceuticals for androgenetic alopecia (hair loss). The minoxidil component helps widen blood vessels, improving blood flow and supplying oxygen/nutrients to hair follicles, while finasteride blocks DHT (a hormone linked to hair thinning) to prevent further hair loss. It’s applied directly to the scalp (typically 1 mL/day) with a spray or dropper, and is formulated for external use only.
