Oral minoxidil works by widening blood vessels and improving circulation to the scalp, which enhances oxygen and nutrient delivery to hair follicles. It also shortens the hair shedding phase (telogen) and prolongs the active growth phase (anagen), encouraging healthier, thicker strands over time.
Unlike topical formulations, oral minoxidil provides systemic delivery, making it a convenient option for those who find topical use messy, irritating, or ineffective.
