Hair growth-promoting effect of oleuropein in C57BL/6N mice.

<p>The back skin of male C57BL/6N mice (eight weeks old) was shaved and treated daily with CON, 0.4 mg OP, or 3 mg MXD for 28 days. (A) The back skin was photographed at 0, 7, 14, 21, and 28 days. (B) The length of randomly plucked hairs was measured at different time intervals (0, 7, 14, 21, and 28 days) after topical application of CON, OP, or MXD. Values are the mean ± SD of eight mice. ns = <i>p</i> > 0.05, *** = <i>p</i> < 0.001 (one-way ANOVA, Tukey's test).
