Objective: The aim of the study is to establish normal values of measurable parameters, set the standard, and provide a framework for future reference. Materials and Methods: A total of 750 children of Malayalam speaking ethnicity with no hair or scalp diseases in anamnesis and clinical examination were included in the study. Children were divided into six age groups (neonates, infants, 1–5, 6–10, 11–14, and 15–17 years), and trichoscopy was performed in frontal, left and right temporal, vertex, crown, and occiput using Wi-Fi cordless digital dermoscope. Hair shaft, follicular opening, and perifollicular and interfollicular area were evaluated and analyzed with SPSS software. Results: Among the parameters analyzed, we observed that with 0.95 probability (95%), the terminal: vellus ratios are (26,29), (22,25), (22,26), (29,33), (25,29), and (19,24) in neonates; (11,14), (7,11), (9,13), (13,17), (12,16), and (7,12) in infants; (16,17), (10,11), (10,11), (16,18), (15,16), and (14,15) in 1–5 years; (17,18), (11), (11), (19,21), (23), and (16,17) in 6–10 years; (17,18), (9,10), (10), (19,20), (18,19), and (16,17) in 11–14 years; and (14,15), (8–9), (8,9), (15,16), (14, 16), and (13,14) in 15–17 years. Likewise, we have documented the various trichoscopic findings of different age groups. Conclusion: We propose the summary of trichoscopic patterns of different age groups with normal hair and scalp to accurately identify the abnormal.
