Hair follicle growth in telogen-matched C57BL/6 N mice treated with T. orientalis extract. The effect of T. orientalis extract (5.05 mg/cm²/day) on the hair follicles in telogen mice was analyzed using hematoxylin-eosin (H&E) staining. (a) Longitudinal sections of the back skins (0, 7, 14, and 21 days) were stained, and the image shown is a representative picture of 10 mice. Bars, 100 μm. A–D, control; E–H, T. orientalis extract; I–L, 1% minoxidil. (b) Quantitative histomorphometric analysis. Y axis, hair cycle score value; X axis, progress of hair follicles in the hair cycle, assessed by histomorphometry: telo, telogen; ana I–VI, anagen I to VI; left, hair cycle score values. Values are mean ± standard deviation (S.D.) (n = 30 hair follicles/mouse; ^* p < 0.05, vs. 1% minoxidil).
