From: Piperine reduces hair oiliness by inhibiting adipogenesis of hair stem cells
Effect of piperine on body weight and hair oiliness in mice fed a HFD. (A) Photographs of a representative mouse of each group after 18 weeks of feeding a normal diet (ND), piperine-supplemented ND, high-fat diet (HFD), or piperine-supplemented HFD. (B) Effect of piperine on sebaceous gland (SG) size. Back skin samples were stained with H&E. Yellow dashed line: SG. (C) Oil Red O (ORO) staining and quantification of SGs in back skin. ORO staining was followed by H&E staining to visualize hair follicles. White dashed line: SG. Scale bars, 75 μm. Image J was used to quantitate the SG size. Results are means ± SD (n = 5, ***p < 0.001)
