To analyze the clinical characteristics of patients with androgenic alopecia (AGA). Methods A total of 152 patients with AGA who were treated in the hair disease clinic of Jiangsu Taizhou Jiangyan District Institute of Dermatology from December 2019 to February 2023 were selected as the research subjects. The clinical characteristics and sex specificity were analyzed. Results There were 64 males and 88 females in 152 patients with AGA. The age was 13-49 years old, with an average age of (31.25±7.62) years old. There were 48 patients (31.58%) with a family history of immediate family members, including 24 males (37.50%) and 24 females (27.27%). There was no statistically significant difference in the proportion of patients with family history between different genders (P >0.05). The hair loss grading in AGA patients was mainly mild hair loss, and there was no statistically significant difference in hair loss grading among AGA patients of different genders (P >0.05). Among AGA patients, damp-heat accumulation type was the most common (40.13%), followed by liver depression and blood stasis type (14.47%) and liver-kidney deficiency type (12.50%), there was a statistically significant difference in TCM syndrome differentiation types among AGA patients of different genders (P <0.05). Among 152 patients with AGA, the proportion of >20% hair shaft diameter thinning,hair follicle opening without hair shaft, and vellus hair increased was the highest, accounting for 89.47%, 55.26%, and 51.32%, respectively. There was no significant difference in skin (hair) mirror signs among AGA patients of different genders (P >0.05). There was no significant difference in the frequency of shampooing between AGA patients of different genders (P >0.05). The proportion of female AGA patients with hot hair dyeing habits was higher than that of male patients (P <0.05). The proportion of scalp oily and hair oily in male AGA patients was higher than that in female AGA patients (P <0.05). The proportion of average sleep time <8 h in female AGA patients was higher than that in male AGA patients (P <0.05). Conclusion The age of AGA patients shows a younger trend, the course of disease is short and mainly mild alopecia, which is related to factors such as heredity, lifestyle, oil secretion and sleep time, and has certain gender specificity. Hair mirror signs and TCM syndrome differentiation can guide clinical diagnosis and treatment.
