Rogaine is FDA-approved for treating androgenetic alopecia (pattern hair loss) in men and women. It is most effective for hair loss at the crown of the head and early-stage thinning. Women typically use the 2% formulation, while men often use the 5% solution.
Minoxidil is a vasodilator that widens blood vessels and opens potassium channels when applied topically. This increases blood flow, oxygen, and nutrient delivery to hair follicles, reversing the miniaturization process and prolonging the anagen (growth) phase of the hair cycle, resulting in thicker hair regrowth.
Consistent use for 2-4 months is typically needed before visible results appear, and discontinuation will lead to gradual reversal of regained hair. Common side effects include scalp irritation, dryness, and unwanted facial hair growth. Women who are pregnant or breastfeeding should consult a healthcare provider before use. The medication should not be used on inflamed, infected, or irritated scalp.
