    Studysummary This study found that a microneedle patch containing tofacitinib-loaded nanoparticles significantly increased hair follicle numbers and promoted hair regeneration with less drug compared to daily topical tofacitinib, suggesting it may be an effective strategy for alopecia treatment by reducing dosing frequency and enhancing drug delivery.
