December 2025 in “Al-Azhar International Medical Journal /Al-Azhar International Medical Journal” This study compared the diagnostic validity of Folliscope and Trichoscope in 100 male patients with androgenetic alopecia. Results showed that both methods revealed regional variations in hair characteristics, with occipital hair being thick and dense, while frontal and vertex areas exhibited thinning and miniaturization. The terminal-to-vellus hair ratio was highest in the occipital region, which is valuable for transplantation. Age negatively correlated with hair density and thickness in androgen-sensitive areas. The study concluded that trichoscopy and folliscopy provide complementary insights, with trichoscopy highlighting diagnostic patterns and folliscopy offering objective measurements, thus enhancing diagnostic accuracy when used together.
