An essential vasodilator with some anti-androgenic effects
- Minoxidil 2%, 5% and 10% which is better to use? In a randomized trial in men, 5% topical minoxidil produced more hair growth than 2%. There is no approved 10% product and no head-to-head trial showing it beats 5%; higher strengths mainly add irritation and systemic absorption. Approved strengths differ by sex, so check the label for your product.
- From hypertension to hair: the unexpected story of minoxidil Minoxidil was developed as an oral blood-pressure drug and approved as Loniten in 1979; unwanted hair growth in patients led to topical Rogaine, approved for men in 1988 and for women in 1991. Trials support topical minoxidil for pattern hair loss, while low-dose oral minoxidil is a prescription drug used off-label and needs medical supervision.
signaling protein that, when suppressed, may grow hair by reducing inflammation and stem cell loss
a synthetic prostamide used to treat eyelashes also shows promise for stimulating hair growth on scalp
- How does bimatoprost compare to minoxidil for hair regrowth? Minoxidil is FDA-approved for scalp hair loss and backed by decades of large trials; bimatoprost is approved only for eyelashes, and the published scalp evidence is limited to small short studies, so on the scalp it is off-label and experimental.
- Is latanoprost more effective for hair regrowth than minoxidil? No trial has compared latanoprost and minoxidil head to head. Minoxidil has large randomized trials and FDA approval for hair loss, while latanoprost's scalp evidence is a single 24-week pilot in 16 men, so the published evidence does not support latanoprost being the more effective option.
