Biological Activity Endogenous estrogen receptor ligand . Application: Alfatradiol is used in form of an ethanolic solution for topical application on the scalp. Similarly to other drugs against alopecia, topical or oral, it has to be applied continuously to prevent further hair loss. Regrowth of hair that was already lost is only possible to a limited extent. In general, advanced alopecia does not respond well to medical treatment, which has historically been thought to be a consequence of the hair roots being lost. A university-led study (including several authors who are advisors to companies) in 103 women comparing alfatradiol to minoxidil, another topical hair loss treatment, found the latter to be more effective. In contrast to minoxidil, alfatradiol did not result in an increase of hair density or thickness, but only in slowing down or stabilization of hair loss in this study. In an earlier study, no systemic side effects were noted, and 17α -estradiol was found to reduce androgenic hair loss, though it was not effective at growing new hair.
