Needle-Free Jet Delivery of Minoxidil in Early Female Pattern Hair Loss: An Observational Comparative Study in Asian Women

This observational study involving 40 Asian women with early female pattern hair loss (FPHL) found that combining needle-free intradermal minoxidil delivery with standard topical therapy significantly improved hair growth compared to topical minoxidil alone. The combination group showed a higher proportion of participants achieving a ≥ 10-hair increase (75.0% vs. 40.0%) and a greater increase in mean hair shaft diameter (4.1 ± 2.6 μm vs. 2.3 ± 2.4 μm). The Global Aesthetic Improvement Scale (GAIS) also favored the combination group, with no serious adverse events reported. The study suggests that needle-free intradermal minoxidil delivery is a well-tolerated and potentially effective adjunct to standard therapy, though further research is needed to confirm its long-term effectiveness.
