Summary: Corticotropin-releasing hormone (CRH) is a key mediator in stress-induced hair growth inhibition. Here, we investigated the impact of stress-induced senescence and evaluated the potential of Ganoderma lucidum (GL) extract in mitigating CRH-induced senescence in human hair follicle cells (hHFCs). We show that CRH treatment increased the senescence-associated beta-galactosidase (SA-β-GAL) activity and reactive oxygen species (ROS) formation in hHFCs and suppressed alkaline phosphatase (ALP) activity and anagen-inducing genes. However, GL extract restored ALP activity and decreased the expression levels of anagen-related genes in CRH-treated hHFCs. It decreased SA-β-GAL activity, reduced ROS production, and prevented the phosphorylation of MAPK signaling pathways in CRH-related stress response. Moreover, GL reversed the CRH-induced inhibition of two-cell assemblage (TCA) elongation and Ki67 expression. GL extract attenuates stress-induced hair follicular senescence by delaying catagen entry and scavenging ROS. Our findings suggest that GL extract could be used for treating stress-induced hair loss.
