Assessing the Effectiveness and Safety of Poly-L-Lactic Acid Microsphere Injections for Treating Male and Female Pattern Hair Loss

This study investigates the safety and effectiveness of Juläine, an injectable treatment with poly-L-lactic acid microspheres, for androgenetic alopecia in 20 men and women aged 20 to 60. Conducted at Ouronyx Clinic in London, participants received three scalp injection sessions over 9 weeks, with follow-ups at Weeks 13 and 20. The study measures hair density and thickness improvements using trichoscopy and photography, alongside participant-reported quality of life and satisfaction. The study aims to show that Juläine can safely promote hair regrowth by stimulating collagen synthesis and tissue remodeling.
