- How does tofacitinib differ when used orally versus topically in hair loss treatment research? Oral tofacitinib acts on immune signalling throughout the body and has more published regrowth data in alopecia areata (from small studies without placebo groups), alongside an FDA boxed warning; topical tofacitinib aims to act only on the scalp, but the human evidence is a handful of small compounded-formulation studies with no large randomized trial. Neither route is approved for hair loss, and regrowth generally reverses after treatment stops.

- Does Alfatradiol work the same for women, men, and trans people? Almost all controlled data on topical alfatradiol comes from cisgender women, where hair density and thickness stayed nearly unchanged over 6 months while minoxidil improved them (the trial had no placebo group). No published controlled trial covers cisgender men, and none covers trans people at all — so the honest answer is that the difference has not been measured.
- Alfatradiol: Can it help if my hair loss is linked to DHT? The one randomised trial of topical alfatradiol — in 103 women — found hair thickness and density essentially unchanged after six months, while minoxidil improved both; its authors credited alfatradiol with slowing hair loss, but the trial had no placebo group to test that. Laboratory work on isolated follicles suggests a local effect on DHT, but no controlled trial in men appears to have been published.
- How long should I wait to see if Alfatradiol is working for me? The one randomised trial and community reports both point to waiting at least 3 to 6 months. That trial, in about 100 women over six months with no placebo group, found no improvement in hair thickness or density; its authors credited alfatradiol with slowing hair loss.
