Investigation of grape sap on wingless/integrated and β-catenin genes expression with histological factors on the hair follicle in rat.

Background And Purpose: Natural products are used to improve the damage caused by harmful reagents in various pathological situations. This study investigated the effect of grape sap as a natural product with antioxidant properties on follicle cell proliferation in bleomycin (as a chemotherapy agent with toxic effects on hair growth) treated rats skin.
