This study developed a prototype device that suggests potential for diagnosing changes in hair quantity, diameter, and density, though formal clinical studies are needed to confirm these findings.

The trichometer accurately measures hair growth and is easy to use.

This study suggests that a prototype device may accurately measure hair quantity, diameter, and density in balding patients, potentially aiding in diagnostic assessments, though formal clinical studies are needed to confirm its effectiveness.

Patient-reported hair improvements align with actual hair density changes, not hair width.

This case report identifies a new type of hair matrix tumor called "rippled pattern trichomatricoma," distinguished by its unique cell arrangement and differentiation features.

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 found that the cross-section trichometer is a promising tool for measuring hair mass index with high reproducibility, suggesting potential clinical and research applications.

In this study, cross-section trichometry was found to be a precise method for measuring hair loss in chemotherapy patients, but marking the measurement site on the scalp is not always necessary.

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.

This review updates on various methods for hair and scalp examination, encompassing non-invasive, semi-invasive, and invasive techniques, and reports no new results.

This article discusses the off-label use of low-dose oral minoxidil for alopecia and reports no new clinical findings, noting its presumed mechanism is enhancing hair follicle microcirculation with minimal blood pressure effects.

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.

In this 10-patient exploratory study, the researchers found that topical application of 4-aminopyridine 5% combined with microneedling did not improve hair density or quality in men with androgenetic alopecia, suggesting limited efficacy in this context despite promising results in animal wound models.

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.

This study, examining perceptible hair density changes in androgenetic alopecia patients, found that dermatologists could accurately detect hair loss at a lower threshold than previously noted, specifically at a 22.66% relative density difference, challenging assumptions about their predictive accuracy based solely on clinical examination.

In this study, the researchers measured and discussed the friction and wear properties of various hair types against synthetic skin and other hair, finding variations based on factors like ethnicity, hair condition, and environmental conditions.

Hair damage shows as fragility, dullness, and discoloration, varies by ethnicity, and is worsened by cosmetic procedures and diseases.

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.

This study found that the cross-section trichometer (HairCheck device) can accurately and sensitively measure hair mass index changes, offering a convenient tool for assessing hair density and diameter in patients with alopecia.

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.

This study suggests that using trichotillometry to establish the normal range of shear strain for different hair types could inform diagnostic and treatment decisions for various hair conditions.

This article describes various hair and scalp examination techniques, including noninvasive, semi-invasive, and invasive methods, noting that trichoscopy is a simple, well-accepted, noninvasive technique for evaluating hair loss patients and monitoring treatment.

The document concludes that the trichogram is a useful tool for diagnosing hair loss and suggests semi-organ cultures for practical trichological research.

This abstract provides no results; it is a website notification about cookies and general access to JAMA content.

This study found that Trichoscope can effectively reveal clinical features of alopecia areata and androgenic alopecia, making it a useful tool for diagnosis and monitoring.

This study developed a high-resolution phototrichogram system that can automatically and accurately assess hair growth metrics in cosmetic trials, achieving over 90% correlation with manual measurements.

This article reviews the use of trichoscopy for diagnosing and monitoring various scalp conditions, but it presents no new experimental findings; the authors emphasize its precision in noninvasive evaluation.

TrichoScan accurately measures hair growth and loss, showing increased hair counts and thickness with treatment.

This study reported that Trichoscan, a computer-assisted hair measurement system, was not supported as accurate for clinical trials due to errors in signal detection, despite its analysis speed.
