learn Minoxidil
Vasodilator used on the scalp and, at low doses, as a tablet
- 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%, and in one small trial 10% did not beat 5% and caused more irritation. No 10% product is approved in the US, and 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.
- Shampoos, vitamins and other promises: What does minoxidil really boost? Topical minoxidil is approved for pattern hair loss; there is no good evidence that shampoos, biotin or other added ingredients boost its effect.
