Hair loss can be assessed objectively by examining a hair pull sample for stage of growth and hair shaft diameter, getting an estimate of average daily hair loss, and mapping scalp hair density. The history of the loss, the clinical picture, and the growth stage and diameter of the hair when lost all help to establish the type of loss. Hair regrowth occurs without treatment in most types of hair loss. There is as yet no effective treatment for pattern or senescent alopecia, although in women the loss can now be retarded somewhat.
通过检查拔下的毛发样本的生长阶段和毛干直径、估计每日平均脱发量以及绘制头皮毛发密度图，可以客观地评估脱发情况。脱发的病史、临床表现以及脱发时毛发的生长阶段和直径，都有助于确定脱发的类型。大多数类型的脱发在未经治疗的情况下也会重新长出头发。尽管目前对女性的脱发情况可以在一定程度上延缓，但对于雄激素性脱发或老年性脱发，尚无有效的治疗方法。
