From: Piperine reduces hair oiliness by inhibiting adipogenesis of hair stem cells
Suppression of hDPC adipogenesis by piperine. Statistical results are means ± SD (n = 3, ***p < 0.001). (A) Micrographs of ORO-stained adipogenic hDPCs. Effects of 50 and 100 µM piperine were evaluated. (B) ORO staining was quantitated by measuring the absorbance at 500 nm using a spectrophotometer. (C) Effect of piperine on the expression of PPARγ target genes by RT-qPCR after differentiation of hDPCs in the presence of piperine. C: culture medium; D: differentiation medium; D + 50: 50 µM; D + 100: 100 µM piperine
