Naminidil (also known as Minoxidil) is a potent vasodilator used primarily in two contexts: orally for treating severe hypertension by relaxing blood vessels to improve blood flow and reduce blood pressure, and topically in dermatology for promoting hair growth. In topical formulations like lotions or solutions, it treats androgenetic alopecia (pattern baldness) by stimulating hair follicles, enhancing scalp circulation, encouraging regrowth, and reducing hair loss. It may be combined with other ingredients for improved efficacy in hair care products. Use requires medical supervision to avoid side effects such as dizziness, edema, hypotension, or hypertrichosis. Studies also suggest potential benefits in heart failure management.
