    TLDR The HairCheck® device is effective for measuring hair loss and growth in people with alopecia.
    The document discussed the use of cross-section trichometry (CST) as a clinical tool for assessing the progression and treatment response of alopecia by measuring the cross-sectional area of hair fibers. The study evaluated the HairCheck® device, derived from the cross-section trichometer, and found it to be accurate, precise, and sensitive in measuring hair mass changes. The Hair Mass Index (HMI) showed strong correlations with the number, diameter, and weight of hair strands, making CST a reliable method for monitoring hair density and thickness. CST was particularly useful for early detection of androgenetic alopecia, setting realistic expectations for hair transplantation, and evaluating the efficacy of treatments like minoxidil, finasteride, and laser therapy. It also helped in assessing hair breakage severity and monitoring responses to therapies for thyroid and iron deficiencies.
