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

This study found that measuring hair thickness with a phototrichogram provided significantly thicker readings than using a micrometer caliper, suggesting that the phototrichogram may be more clinically useful for evaluating hair in patients undergoing hair transplantation.

This study found that in male androgenetic alopecia, the contrast enhanced phototrichogram technique was superior in detecting changes in hair density and thickness compared to other methods.

This study found that contrast enhanced phototrichogram (CE-PTG) significantly improved detection of various hair types and growth stages in androgenetic alopecia compared to standard PTG and was comparable to biopsy analysis.

This study compared the diagnostic effectiveness of Folliscope and Trichoscope in 100 men with androgenetic alopecia, concluding that using both methods enhances diagnostic accuracy by providing complementary insights—Trichoscope highlights patterns while Folliscope offers objective measurements.

This study found that photoepilation using intense pulsed light significantly reduced hair growth parameters, and phototrichograms may offer an objective method to evaluate its effectiveness.

This study reports that scalp biopsies in white adults usually have 16.5 hair follicles, primarily in the anagen phase, with male samples showing fewer follicular units but more fibrous tracts in certain areas.

This review discusses the role of scalp imaging techniques in trichology for researching drug delivery and toxicology, without presenting new clinical results.

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 developed a novel system that can automatically estimate hair loss parameters from images without expert input, reporting satisfactory results from testing on samples collected in Kolkata.

This study observed that Koreans generally have lower hair density, larger diameter, and slower growth rate compared to Caucasians, providing useful baseline data for studying hair diseases and treatments.

This study observed that hair density and thickness were significantly reduced across multiple scalp sites in South Korean women with hair loss, highlighting potential patterns that could aid in differentiating hair disorders.

This study introduces a non-invasive photoacoustic imaging technique that accurately measures hair follicle density and subdermal angles, showing strong correlation with the gold-standard photographic method.

This review examines various methods for assessing hair growth in women, highlighting the usefulness of the mFG visual scoring method for diagnosing hirsutism despite its limitations.

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

Trichoscopy is better than trichogram for diagnosing early female hair loss.

This study found that the TrichoScan method detected significant increases in hair counts and cumulative hair thickness in men after finasteride treatment, suggesting its potential for monitoring hair treatment responses.

Phototrichogram helps assess hair loss severity.

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 review discusses the use of hair microscopy in diagnosing hair-related conditions, highlighting techniques and common applications, but presents no new experimental results.

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 review discusses how trichoscopy is becoming a preferred non-invasive diagnostic tool over trichograms for evaluating hair disorders, although it reports no clinical results.

In this study, Trichoscan®, reflectance confocal microscopy, and optical coherence tomography were found to be reliable noninvasive tools for measuring hair growth and follicle analysis after hair removal.

This study found that the TrichoScan Professional V3.0.8.76 shows high reproducibility in measuring hair count and density but may not be effective for distinguishing hair growth phases in women with androgenetic alopecia.

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

In this study with stumptailed macaques, topical minoxidil successfully induced hair regrowth on bald scalps and prevented baldness on non-bald scalps, with no observed side effects over nearly three years.

This study describes a system called FOLLYSIS©, which uses mathematics and image analysis to optimize Follicular Unit Extraction hair transplants, showing high accuracy in measuring donor area density and reducing donor site injury.

This study found that miniaturization of hair is present in some women with androgenetic alopecia, but diagnosis may also be based on differences in hair shaft diameter between scalp regions.

This review evaluates hair growth measurement methods for human scalp hair, suggesting that combining highly resolutive analytical approaches with global calibrated methods is recommended for assessing hair changes in clinical settings.

This study found that laser-based goniophotometry can effectively monitor changes in hair surface reflection related to color and cuticle cell tilt across different ethnic origins.
