Topical Application of Oleuropein Induces Anagen Hair Growth in Telogen Mouse Skin
Topical Application of Oleuropein Induces Anagen Hair Growth in Telogen Mouse Skin.
Tong T1, Kim N1, Park T1.
Abstract
METHODOLOGY AND PRINCIPAL FINDINGS:
Oleuropein promoted cultured human follicle dermal papilla cell proliferation and induced LEF1 and Cyc-D1 mRNA expression and β-catenin protein expression in dermal papilla cells. Nuclear accumulation of β-catenin in dermal papilla cells was observed after oleuropein treatment. Topical application of oleuropein (0.4 mg/mouse/day) to C57BL/6N mice accelerated the hair-growth induction and increased the size of hair follicles in telogenic mouse skin. The oleuropein-treated mouse skin showed substantial upregulation of Wnt10b, FZDR1, LRP5, LEF1, Cyc-D1, IGF-1, KGF, HGF, and VEGF mRNA expression and β-catenin protein expression.
CONCLUSIONS AND SIGNIFICANCE:
These results demonstrate that topical oleuroepin administration induced anagenic hair growth in telogenic C57BL/6N mouse skin. The hair-growth promoting effect of oleuropein in mice appeared to be associated with the stimulation of the Wnt10b/β-catenin signaling pathway and the upregulation of IGF-1, KGF, HGF, and VEGF gene expression in mouse skin tissue.

Re: Topical Application of Oleuropein Induces Anagen Hair Growth in Telogen Mouse Skin
Is it similar to olive oil? Olive leaf from the tree instead of the olive, so probably not...
