TLDR Minoxidil may help hair growth by stopping immune system attacks on hair follicles.
This 1985 study found that minoxidil has immune-suppressive effects on human lymphocytes in vitro, suggesting that it may work by suppressing the immune system's attack on hair follicles in individuals with pattern baldness or alopecia areata.
