The outer cuticle, middle cortex, and inner medulla make up hair, which is an epidermal outgrowth. Hair is resilient under harsh natural conditions, thus it is frequently collected at crime scenes, making human hair analysis important in the forensic sciences field. It aids in the formation of a triangle connecting a crime scene, a victim, and a culprit. The aim of this study is to observe the microscopic structure of male and female human hair. Samples of hair specimens from males and females were collected. The materials used were ethanol to degrease and a stereomicroscope to observe the structural differences between the male and female hair samples. The comparison between male and female hair is done on the grounds of color, shaft profiles, the proximal and distal ends of the hair, cuticle, and surface texture, and the other found characters. This study of comparison between male and female hair specimens revealed that the hair color at the distal end is found to be brown for females while it is completely black in that of males, and the surface texture of males is found to have some irregularities while there are no irregularities in female. This study can be concluded that the structural comparison between male and female hair specimens can be used as evidence for forensic analysis at crime scenes.
外层角质层、中层皮质和内层髓质构成了毛发,毛发是一种表皮衍生物。在恶劣的自然条件下,毛发具有弹性,因此它经常在犯罪现场被采集到,这使得人类毛发分析在法医学领域很重要。它有助于形成一个连接犯罪现场、受害者和罪犯的三角关系。本研究的目的是观察男性和女性人类毛发的微观结构。收集了男性和女性毛发样本。使用的材料是用于脱脂的乙醇和用于观察男性和女性毛发样本结构差异的体视显微镜。对男性和女性毛发的比较基于颜色、发干轮廓、毛发的近端和远端、角质层、表面纹理以及其他发现的特征。对男性和女性毛发样本的比较研究表明,女性毛发远端的颜色为棕色,而男性的则完全是黑色,男性的表面纹理有一些不规则之处,而女性的则没有不规则之处。可以得出结论,男性和女性毛发样本的结构比较可作为犯罪现场法医分析的证据。
