Abstract： 目的 探讨中国成年男性头发的生长特性.方法 将31名志愿者头皮顶部及颞部各剃去约1.2 cm×1.2 cm范围内的头发;间隔7天后对上述部位微距照相,分析图像,得到头发密度及头发生长速度;拔取观察部位的头发,显微镜下测量头发尖端、中部及根部的直径.结果 31例成年男性头发密度为(132±42)根/cm2,顶部的头发密度显著高于颞部(P＜0.001).头发生长速度为(46l±44)μm/d,颞部的头发生长速度显著高于顶部(P＜0.01).头发直径为(97±9)μm,顶部和颞部之间头发直径差异无统计学意义(P＞0.05),头发尖端、中部及根部之间直径的差异亦无统计学意义(P＞0.05).结论 与白人和非洲人相比,中国成年男性头发的密度较低,但头发生长速度较快.
