research Vitamin B12 Activates the Wnt-Pathway in Human Hair Follicle Cells by Induction of <i>beta</i>-Catenin and Inhibition of Glycogensynthase Kinase-3 Transcription
This study demonstrated that vitamin B12 may promote hair growth in vitro by modulating intracellular signaling in the wnt-pathway, suggesting potential benefits for micrograft transplantation.
