This case report observed that a 44-year-old male patient with androgenetic alopecia experienced increased hair density and patient satisfaction after treatment with microneedling, growth factors, and minoxidil.
This study reviews existing literature on regenerative therapy for androgenetic alopecia, highlighting that integrating growth factors, biotin, D-pantenol, and other active ingredients using the Vittahair protocol may enhance hair follicle regeneration, increase hair density, and improve hair quality, providing a precise and evidence-based treatment alternative.
