September 2026 in “Journal of Biophotonics” This study indicates that microwave-assisted Opuntia humifusa extract combined with Red-LED irradiation may better modulate intracellular redox status and Wnt/β-catenin-related protein expression in human hair follicle dermal papilla cells than each treatment alone.
January 2024 in “Annals of Agricultural and Environmental Medicine” This study observed that LED therapy improved hair regrowth and reduced hair loss in patients with post-COVID telogen effluvium, with or without androgenetic alopecia, compared to those who did not receive LED treatment.
April 2021 in “Institutional Repositories DataBase (IRDB)” This study reported that high-intensity red LED irradiation increased osteogenic differentiation and mineralization of human bone marrow mesenchymal stem cells, potentially through Wnt/β-catenin pathway activation.
January 2026 in “Journal of Hard Tissue Biology” This study found that red LED photobiomodulation significantly enhanced both the metabolic activity and proliferation of human placenta-derived pericytes, alongside increased expression of angiogenic markers, suggesting a potential non-invasive approach to aid tissue repair and vascular regeneration.
January 2016 in “프로그램북(구 초록집)” In this study, LED irradiation was found to promote hORSC proliferation and stimulate the Wnt5a/β-catenin and ERK signaling pathways, suggesting a potential mechanism for hair growth.
