240-270 / 1000+ results research Characterization of the lipid composition at the proximal root regions of human hair
Human hair contains various lipids that vary among individuals and help protect the hair.
research Gas chromatography/mass spectrometry based hair steroid profiling may reveal pathogenesis in hair follicles of the scalp
Analyzing hair with this method can help understand and monitor scalp conditions and treatment effects.
research Methods in hair research: how to objectively distinguish between anagen and catagen in human hair follicle organ culture
A reliable system was developed to distinguish hair growth stages, aiding in identifying hair growth promoters or inhibitors.
research [Keratin dielectric parameters in the millimeter wavelength range].
Human hair affects millimeter radiowaves due to its keratin content.
research Investigation by Imaging Mass Spectrometry of Biomarker Candidates for Aging in the Hair Cortex
Certain molecules in hair change with age and could be used for cosmetic treatments.
research Assessment of hair re-growth and the correlation between hair cortisol and faecal glucocorticoid metabolite concentrations in captive wolves
Hair cortisol levels in wolves reflect stress and vary by season and body region.
research Comparative Studies of the Diameters of Hairshafts in Anagen and in Telogen Phases in Male Adults Without Alopecia and in Male Adults With Androgenetic Alopecia
research Integral characterization of normal and alopecic hair at different degeneration stages by in-situ visible and chemical imaging
Alopecic hair has more irregular structures and chemical changes than normal hair, reducing its strength.
research A preliminary study of steroid reproductive hormones in human hair
Human hair can be used to measure reproductive hormones.
research Exploring a biological tissue from atomic to macroscopic scale using synchrotron radiation: example of hair.
Hair has unevenly distributed proteins and lipids, with lipids mainly in the cuticle and proteins in the cortex and medulla.
research 115 Distributions of type XII and XIV collagens in adult skin and the anagen hair follicle
research Gender Differences in Mouse Skin Morphology and Specific Effects of Sex Steroids and Dehydroepiandrosterone
Male and female mice have different skin thickness, and hormones affect their skin and hair growth differently.
research Segmental analysis of human hair reveals intra-annual variation in 25(OH)D3 concentrations in modern and archaeological individuals
Hair analysis can show changes in vitamin D levels over time.
research Microanatomical Observations of Hair Characteristics of Red Fox (Vulpes vulpes), Golden Jackal (Canis aureus), and Gray Wolf (Canis lupus): A Comparative Study
Red fox, golden jackal, and gray wolf hairs have similar features but differ in length, thickness, and inner structure.
research The Alopecia Areata Investigator Global Assessment scale: a measure for evaluating clinically meaningful success in clinical trials
The AA-IGA scale reliably measures treatment success in alopecia areata by considering both clinician and patient views.
research Hair diameter vs. hair density in male androgenetic alopecia
Hair loss is due to thinner hairs, not less hairs; hair diameter indicates balding progression and treatment effectiveness.
research Chronological ageing of human hair keratin fibres
Hair ages as the cuticle wears down, especially beyond 1 meter from the root, affecting its strength and shine.
research Evaluation of Hair Density and Hair Diameter in the Adult Egyptian Population using Quantitative Trichoscopic Analysis
Trichoscopy is a quick, non-invasive way to measure hair density and thickness, helping diagnose hair loss.
research The ultrastructure of the interfollicular epidermis of the hairless (hr/hr) mouse
research Hair cortisol analysis: An update on methodological considerations and clinical applications
Hair cortisol analysis can help diagnose stress-related conditions but needs more refinement for widespread use.
research Development of the Hair & Scalp CARE questionnaire: Measuring the impact of hair and scalp issues on psychological wellbeing in healthy populations
Healthier hair and scalp improve mental wellbeing.
research Expression of mRNA for androgen receptor, 5alpha-reductase and 17beta-hydroxysteroid dehydrogenase in human dermal papilla cells
Hair sensitivity to androgens is partly controlled by specific enzyme expressions in different hair areas.
