This study investigated the effect of herbal extracts fermented by Lactobacillus plantarum (MBN) on hair growth in C57BL/6 mice and HaCaT cells. Five week old mice were applied with MBN topically (0.2 mL) once per for 21 days. Hair regrowth was evaluated by gross examination and verified by hematoxylin-eosin staining. Gene expression of vascular endothelial growth factor (VEGF), keratinocyte growth factor (KGF), and transforming growth factor-beta1 (TGFβ1), relevant to hair growth, were examined. The data revealed that MBN successfully promoted hair growth in both male and female mice at a dose between 200-500 mg/kg and improved hair thickness. The VEGF and KGF genes were expressed in a dose-dependant manner, whereas TGFβ1 was not expressed. Moreover, nitric oxide was significantly increased, suggesting an improvement in blood flow. These results indicate that MBN effectively promoted hair growth and gene expression relevant to hair growth in an animal model.
