Potential mechanisms of minoxidil-induced hair growth in alopecia areata.
Fiedler-Weiss VC.

Minoxidil treatment causes changes in the follicular epithelium, etc… Biopsy of areas of terminal hair regrowth show a dose-dependent increase in hair follicle length,etc.. snip…. In vitro, at concentrations approximating the range of tissue levels in patients treated topically with the 5% solution, minoxidil affects both epithelial cells and lymphocytes in tissue culture. …snip… Minoxidil may induce hair regrowth in alopecia areata by a synergistic stimulatory effect on follicular epithelium and a suppressive effect on lymphocyte-mediated immunologic phenomena. A contributing role for vasodialation must also be considered.
