TLDR Minoxidil helped slow balding in most cases, but only a few saw significant hair growth.
Minoxidil, initially an oral antihypertensive, was developed into a 2% topical solution for treating androgenic alopecia due to its side effect of hypertrichosis. A study involving 30 cases assessed its efficacy through hair counts and subjective evaluations. The treatment was beneficial in 63% of cases, with most experiencing slowed balding and a minority seeing increased hair density. However, only 6.6% of patients achieved dramatic cosmetic improvement.
April 2023 in “UNESP Institutional Repository (São Paulo State University)” Oral and topical minoxidil are similarly effective for hair growth, but oral may work better on the top of the head.
January 2024 in “Expert Opinion on Pharmacotherapy” Low-dose oral minoxidil is effective and safe for treating hair loss in men and women.
January 2022 in “Al-Mağallaẗ al-ʻirāqiyyaẗ li-l-ṣaydalaẗ” New minoxidil formulations improve hair loss treatment.
