This study was conducted to evaluate the effect of Crinum asiaticum, a plant native to Jeju Island, Korea, on the promotion of hair growth. When rat vibrissa follicles were treated with a 95% ethanol (EtOH) extract of C. asiaticum, the hair-fiber lengths of the vibrissa follicles increased significantly. In addition, after daily topical application of the EtOH extract of C. asiaticum onto the back of C57BL/6 mice, anagen progression of the hair shaft was induced. Moreover, the extract increased the proliferation of immortalized vibrissa dermal papilla cells. When the vibrissa follicles in the anagen phase were treated with the extract, immunohistochemical analysis revealed that the extract was found to increase the expression of proliferating cell nuclear antigen (PCNA) in the bulb region of the 7-day cultured follicles. In particular, norgalanthamine, a principal of the extract, showed activity that increased the hair-fiber lengths of vibrissa follicles and the proliferation of dermal papilla cells. These results suggest that norgalanthamine, a principal of C. asiaticum, has the potential to promote hair growth via the proliferation of dermal papilla.

Norgalanthamine has been shown to possess hair-growth promoting effects, including increase in hair-fiber length in cultured rat vibrissa follicles and increase in dermal papilla cell (DPC) proliferation. However, the intracellular mechanisms that underlie the action of norgalanthamine in DPCs have not been investigated. In this study, we addressed the ability of norgalanthamine to trigger anagen-activating signaling pathways in DPCs. Norgalanthamine significantly increased extracellular signal-regulated kinase (ERK) 1/2 phosphorylation at 0.1 µM, a concentration at which DPC proliferation was also induced. Furthermore, the increases in norgalanthamine-induced ERK 1/2 activation and subsequent DPC proliferation were suppressed by the mitogen-activated protein kinase/ERK kinase (MEK) 1/2 inhibitor, U0126. A 0.1 µM dose of norgalanthamine also increased phosphorylation of AKT, which was followed by an increase in glycogen synthase kinase 3β phosphorylation and nuclear translocation of β-catenin. In addition, LY294002, a phosphatidylinositol 3 kinase (PI3K) inhibitor, blocked the effect of norgalanthamine on DPC proliferation. These results suggest that norgalanthamine can stimulate the anagen phase of the hair cycle in DPCs via activation of the ERK 1/2, PI3K/AKT, and Wnt/β-catenin pathways.
