research Clinical approach to focal hairless patch with dermoscopy
Dermoscopy helps diagnose different hair loss conditions, and characteristics vary among ethnicities and individual cases.
research Efficacy of modern methods for assessing the severity of alopecia areata
The SBN system effectively assesses alopecia areata severity and predicts its course.
research A Murine Model for Inducing and Manipulating Hair Follicle Regression (Catagen): Effects of Dexamethasone and Cyclosporin A
Dexamethasone speeds up hair loss in mice, while cyclosporin A slows it down.
research Three-dimensional architecture of macrofibrils in the human scalp hair cortex
Human hair has a complex, variable structure with a consistent matrix and double-twist pattern.
research Element profiles of mouse hair: A concern for using hair as a timetable repository
Mouse hair element patterns vary, making it unreliable for tracking time.
research Comparative Evaluation of Systemic and Hair Growth Pathways for the Detection and Assessment of Chronic Stress
Hair growth pathways are a promising and simpler method for detecting chronic stress.
research In vitrometabolism of dehydroepiandrosterone and testosterone by canine hair follicle cells
Canine hair follicle cells metabolize DHEA and testosterone differently than human cells.
research Pull Test and Trichogram
Physical exams are important in hair loss diagnosis, considering cosmetic history, systemic diseases, and classifying alopecia types.
research Skin equivalent assay: An optimized method for testing for hair growth reconstitution capacity of epidermal and dermal cells
The 3D skin model is better for hair growth research and testing treatments.
research Evaluation of Hair Loss
The document concludes that a thorough history, physical exam, and specific tests are crucial for diagnosing and managing hair loss effectively.
research Quantification of female pattern hair loss: a study in a Turkish population.
Turkish women with female pattern hair loss have lower hair density, and visual counting is more effective than digital image analysis for detecting this.
research Cuticle damage and the tensile properties of human hair
Cuticle damage doesn't affect hair's tensile strength; the cortex is responsible for it.
research Distinctive or critical histological features and associated diseases
The document concludes that diagnosing hair loss requires evaluating multiple histological features, as no single feature is definitive on its own.
research A Guide for Studying Spatiotemporal Variability in Murine Hair Cycle and Hair Growth Wave Patterns In Vivo
research The Importance of Measuring Hair Density in the Diagnosis and Treatment of Hair Loss
Measuring hair density is crucial for diagnosing and treating hair loss.
research remarks on the evolution of the integumental scale armour
Pangolin scales evolved for protection, hardening with age, due to keratin gene diversification.
research Alopecia areata - need for a revision in morphological classification and scoring
A new classification and scoring system is needed for alopecia areata to better assess severity.
research Exploring Mechanical Niches Identified by Hair Follicle Compression and How These Transduce Proliferation and Differentiation Cues in Epidermally Derived cells.
Less stiff collagen promotes higher cell growth in hair follicles.
research A quantitative ultra-performance liquid chromatography high-resolution mass spectrometry analysis of steroids from human scalp hair
The method can measure multiple steroids in human hair to study long-term steroid metabolism, especially in newborns and children.
research Hair resistance to mechanical wear
Hair's resistance to wear varies by ethnicity and treatment, with less wear indicating stronger hair.
research GC-MS determination of steroids related to androgen biosynthesis in human hair with pentafluorophenyldimethylsilyl–trimethylsilyl derivatisation
The method accurately measures certain steroids in human hair, showing different levels in males and females.
research A quantitative technique to analyze and evaluate microstructures of skin hair follicles based on mueller matrix polarimetry
The technique accurately identifies and evaluates hair follicle structures in skin.
research Characterization of response of murine hair follicle-derived keratinocyte against androgen and testosterone 5α-redactase activity
Mouse hair cells respond to male hormones by growing less, and this can be stopped by certain blockers.
research Protein extraction from human anagen head hairs 1-millimeter or less in total length
A new method was developed to extract and analyze proteins from very short human hairs.
research Evaluation of Automated Measurement of Hair Density Using Deep Neural Networks
Deep learning can accurately automate hair density measurement, with YOLOv4 performing best.
research Automated digital image analysis (TrichoScan) in male patients with androgenetic alopecia; comparison with manual marking of hairs on trichoscopic images
TrichoScan needs optimization as it underestimated hair density by 38.9% compared to manual counting.
research [The effect of 1, 25-dihydroxyvitamin D3 on cultured human hair follicle cells from a patients with vitamin D-dependent rickets type II with alopecia].
DDR-II hair follicle cells don't respond to 1, 25-dihydroxyvitamin D3, aiding diagnosis.
research Measuring changes in chemistry, composition, and molecular structure within hair fibers by infrared and Raman spectroscopic imaging
Infrared and Raman imaging can non-destructively analyze hair structure and help diagnose hair conditions.
research A Comparison of Reticle Size to Determine Follicular Unit Density in Hair Restoration
Smaller reticle sizes are as accurate as the standard size for measuring hair density in hair restoration.
