In this study, we investigated the sensitivity of TrichoScan, a computer-based phototrichogram, in the evaluation of diffuse hair loss in women and the relationship between iron deficiency anemia and hair loss.
We recruited 100 female patients with diffuse hair loss. In all of the patients, a 1-cm2 area of hair located in a temporoparietal region was shortened to 0.5 mm. The shaved scalp regions were stained with black dye. The subject then waited for 12 min. Subsequently, pictures of these regions were taken with a videodermoscope and analyzed with the TrichoScan software program.
The ferritin levels were markedly low in these groups. The ratio of anagen was highest in the telogen effluvium (TE) mild group, followed by the TE severe group, and was lowest in the androgenetic alopecia (AGA) group (P <0.05). The ratio of telogen was markedly higher in the AGA group, and the difference was statistically significant when compared with the other 2 groups (P < 0.05).
The hair analysis results with the TrichoScan software were satisfactory and the results were consistent with the clinical diagnosis. In particular, the use of TrichoScan was very successful in the differentiation between AGA and TE.
本研究旨在探讨基于计算机的毛发图像分析系统（TrichoScan）在女性弥漫性脱发评估中的敏感性，以及铁缺乏性贫血与脱发之间的关系。
我们招募了 100 例弥漫性脱发的女性患者。在所有患者中，将 1cm2 的颞顶区头发剪短至 0.5mm。刮取的头皮区域用黑色染料染色。然后，受试者等待 12 分钟。随后，使用视频皮肤镜拍摄这些区域的照片，并使用 TrichoScan 软件进行分析。
这些组的铁蛋白水平明显较低。生长期比例在休止期脱发（TE）轻度组最高，TE 重度组次之，雄激素性脱发（AGA）组最低（P<0.05）。AGA 组的休止期比例明显较高，与其他 2 组相比差异具有统计学意义（P<0.05）。
TrichoScan 软件的毛发分析结果令人满意，且结果与临床诊断一致。特别是，TrichoScan 在区分 AGA 和 TE 方面非常成功。
