      learn Tofacitinib

      • 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 the stronger regrowth evidence in alopecia areata, 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.
