June 2017 in “Journal of The American Academy of Dermatology” LED light helps hair follicle cells grow and prevents them from dying by activating certain cell pathways.
May 2017 in “Journal of The American Academy of Dermatology” LED light helps human hair root cells grow and prevents them from dying by activating specific growth pathways.
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.

January 2002 in “Development” In this study, repressing β-catenin/Lef1 signalling in mouse epidermis led to progressive hair loss, dermal cysts, and spontaneous skin tumors with sebaceous differentiation, indicating altered keratinocyte differentiation and potential tumourigenic processes.
April 2023 in “Journal of Investigative Dermatology” This study found that matrix progenitor cells in hair follicles move in a conveyor-belt-like fashion along the dermal papilla, changing their transcriptional states and lineage potential as they differentiate into inner hair follicle layers.
