*Red Light (≈655–660 nm): In vitro research demonstrated that red light exposure activates Wnt/β-catenin signaling pathways in human hair follicle cells, which play a key role in initiating the hair growth cycle and stimulating follicular activity.
**Red Light (≈650 nm): Human hair follicle studies showed that red light irradiation prolonged the anagen (growth) phase and supported continued hair shaft production, helping reduce premature transition to shedding.
