Hair is important to trace evidence commonly encountered in almost all criminal cases. Forensic anthropologists routinely compare the morphological characteristics of the hair samples to determine a transfer. Assessment of parameters such as hair density, hair diameter, follicular units, and empty hair follicle/yellow dots are useful for the diagnosis of various hair disorders, monitoring treatment outcomes, and research purposes. The study aimed to analyze the relationship between age and hair density.
The present cross-sectional observational study was carried out at the Department of Dermatology at a tertiary care center. All the subjects attending the Dermatology Outpatient Department fulfilling inclusion criteria were studied. Data were collected after the approval from the Institutional Ethical Committee. The procedure was explained and a written consent was taken. Each patient's hair was parted in the middle and images from a point of roughly 5 inches from the patient's glabella were taken. The parameters such as hair thickness, hair density, hair count, follicular units, and empty hair follicles/yellow dots were noted.
In the present study, the majority of the study subjects belonged to the age group 26-35 years (38%), followed by 18-25 years (34.7%), 36-45 years (20.7%), and least in the age group of 46-55 years (6.7%). In the present study, the mean unit density in males was 104.78 ± 14.33 and that of females was 108.36 ± 17.60.
Mean hair density varies concerning age group in the study population.
毛发对于几乎所有刑事案件中常见的微量证据都很重要。法医人类学家通常会比较毛发样本的形态特征以确定转移情况。评估诸如毛发密度、毛发直径、毛囊单位以及空毛囊/黄点等参数，对于诊断各种毛发疾病、监测治疗效果以及研究目的都很有用。本研究旨在分析年龄与毛发密度之间的关系。
本横断面观察性研究在一家三级医疗中心的皮肤科进行。对所有符合纳入标准且前往皮肤科门诊就诊的受试者进行了研究。在获得机构伦理委员会批准后收集数据。向受试者解释了研究程序并获取了书面同意书。将每位患者的头发从中间分开，从距患者眉间约5英寸处拍摄图像。记录毛发厚度、毛发密度、毛发数量、毛囊单位以及空毛囊/黄点等参数。
在本研究中，大多数研究对象属于26 - 35岁年龄组（38%），其次是18 - 25岁年龄组（34.7%）、36 - 45岁年龄组（20.7%），而46 - 55岁年龄组最少（6.7%）。在本研究中，男性的平均单位密度为104.78 ± 14.33，女性为108.36 ± 17.60。
在研究人群中，平均毛发密度因年龄组而异。
