This study was undertaken to examine the efficacy of essential oil from seeds of Zizyphus jujuba for its potential role on hair growth by in vivo method. Essential oil was applied at different concentrations (0.1%, 1% and 10%) over the shaved skin onto the backs of BALB/c mice and monitored for 21 days. After 21 days, mice treated with 1% and 10% of oil produced a greater effect on the length of hair which were measured to be 9.96 and 10.02 mm, respectively, as compared to the control (8.94 mm). We measured the weight of hair/cm(2) area of dorsal skin and also evaluated hair thickness and hair follicles microscopically after plucking the hair immediately from the shaved area of mice and found the best results for 1% of essential oil-treated mice. From this study, it is concluded that Z. jujuba essential oil possesses hair growth promoting activity.
本研究采用体内方法研究了大枣（Zizyphus jujuba）籽油的功效，以评估其在促进毛发生长方面的潜在作用。将不同浓度（0.1%、1%和 10%）的精油涂抹在 shaved 皮肤的背部，在 BALB/c 小鼠身上进行了 21 天的监测。21 天后，1%和 10%的油处理的小鼠对毛发长度的影响更大，分别测量为 9.96 和 10.02mm，而对照组为 8.94mm。我们测量了背部皮肤/cm(2)区域的毛发重量，并且在立即从 shaved 区域拔出毛发后通过显微镜评估了毛发厚度和毛囊，发现 1%的精油处理的小鼠的效果最佳。从这项研究中可以得出结论，大枣籽油具有促进毛发生长的活性。
