June 2026 in “IP Indian Journal of Clinical and Experimental Dermatology” This study from a tertiary care center in Chengalpattu involved 50 male patients with androgenetic alopecia (AGA) and found that trichoscopic parameters, such as terminal-to-vellus hair ratios, hair shaft diameters, and hair densities, deteriorated with increasing AGA severity. These parameters were significantly associated with factors like family history, higher BMI, increased stress levels, type 2 diabetes mellitus, and early-onset disease. The study concluded that trichoscopy is a valuable, non-invasive tool for diagnosing and monitoring male pattern hair loss, aiding in early risk identification and timely intervention. It also emphasizes the need for a holistic management approach, integrating stress reduction and metabolic control, and calls for further multicentric and longitudinal research to validate its findings.
