In a double-blind, 56-day randomized controlled trial involving 60 participants, a topical formulation combining Centella asiatica extracellular vesicles, recombinant insulin growth factor-1, and fibroblast growth factor-7 significantly enhanced hair growth parameters. The study, conducted at HungKuang University in Taiwan, demonstrated that the complete formulation led to notable increases in hair shaft thickness, density, and length, alongside a reduction in sebum content and hair loss. The findings suggest a promising new approach to scalp care, combining growth factors with plant-derived components, although limitations in study duration and demographics were acknowledged.
1. The trial included 60 patients aged 18-60 years. 2. The study design was double-blinded. 3. The complete formulation showed the most significant hair growth improvements. 4. Hair density increased by 24% in the active group. 5. Participants applied the product daily for 56 days. 6. Statistical significance was noted by day 14. 7. Limitations included the young demographic and potential placebo effects. 8. The research was conducted at HungKuang University, Taiwan.
