January 2012 in “International journal of trichology” This study found that the HairCheck® device, demonstrating high correlation between its Hair Mass Index and hair characteristics such as strand number and diameter, may be an effective tool for assessing hair mass changes in alopecia patients.
This study evaluated the accuracy of the HairCheck device, a cross-section trichometer, and concluded that it effectively measures changes in hair diameter and density for assessing alopecia progression and treatment response.
September 2024 in “Journal of the American Academy of Dermatology” This study found that among 100 Caucasian patients with androgenetic alopecia, dermatologists could discern hair loss at thresholds significantly lower than the previously cited 50% reduction, highlighting the importance of using objective trichometric measurements to improve detection and personalized treatment strategies.
January 2026 in “Journal of Hair Restoration and Regenerative Medicine” This review discusses methods to better identify unsafe donor areas in patients with diffuse unpatterned alopecia, emphasizing non-surgical management when specific diagnostic criteria are met, but reports no new clinical results.
January 2015 in “Hair therapy & transplantation” This review updates on various methods for hair and scalp examination, encompassing non-invasive, semi-invasive, and invasive techniques, and reports no new results.
February 2013 in “Journal of the American Academy of Dermatology” This study found that certain polymorphisms in EGF and EGFR genes may increase susceptibility to alopecia areata in the Korean population, and these genetic variations could be associated with specific symptoms such as nail involvement and body hair loss.
December 2024 in “Indian Dermatology Online Journal” This study established reference values for trichoscopic parameters of hair density and thickness in healthy Indian males, providing a foundation for future research.

April 2009 in “Journal of Dermatological Case Reports” This study established standard trichoscopy norms for adult white females, providing benchmarks for hair thickness, percentage of thin hairs, and pilosebaceous units with single hair across different scalp areas.
This study measured the force required to pluck anagen and telogen hair from volunteers, suggesting that trichotillometry could assess hair strength in alopecia patients and evaluate treatment efficacy.
