January 2007 in “Linchuang pifuke zazhi” The study investigated the effects of licorice on VEGF protein synthesis and mRNA expression in human dermal papilla cells (DPCs). DPCs were treated with various concentrations of licorice for 72 hours, and results showed a significant increase in both VEGF protein levels and mRNA expression compared to controls. The findings suggested that licorice could stimulate VEGF production in DPCs, potentially playing a crucial role in promoting hair growth.

May 2016 in “Experimental and Therapeutic Medicine” The study investigated the expression of matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) during the hair cycle in mice. It found that MMP-2 and MMP-9 had elevated mRNA and protein expression levels during the anagen phase and decreased levels during the catagen and telogen phases. Their activities fluctuated throughout the hair cycle. TIMP-1 and TIMP-2 expression levels were negatively correlated with MMP-9 and MMP-2, respectively. Immunohistochemical analysis showed that MMP-2 and TIMP-2 were present in all hair follicle structures, while MMP-9 and TIMP-1 were localized to specific areas. These findings suggested that MMP-2 and MMP-9 played significant roles in the hair growth cycle.
