research A comparison of vertical versus transverse sections in the evaluation of alopecia biopsy specimens
Using both vertical and transverse sections gives a better diagnosis of alopecia than using one method alone.
research Advanced chemical imaging and comparison of human and porcine hair follicles for drug delivery by confocal Raman microscopy
Confocal Raman microscopy can effectively study drug delivery in hair follicles using pig ear models.
research 0887 Long-lived and genetically-diverse skin organoids derived from murine adult hair follicle stem cells
Researchers created long-lasting, diverse skin organoids from mouse hair follicle stem cells, useful for studying skin.
research The role of the scalp biopsy in the evaluation of alopecia
A scalp biopsy is essential for accurately identifying different types of hair loss.
research Androgenetic Alopecia
The document concludes that signs of male and female pattern baldness include uneven hair thickness, yellow spots, skin discoloration around hair follicles, more thin and soft hairs, and many hair follicles with just one hair.
research [Hair follicle cell mixture forms hair follicle-like structures after subcutaneous implantation in nude mice].
Implanted human scalp cells can regenerate hair-like structures in mice.
research Acquired curved hair is caused by fusion of multiple hair matrix cells
Curved hair can develop when hair cells merge abnormally during growth.
research Detection of Bim and Puma in mouse hair follicles using immunofluorescence and TUNEL assay double staining
Bim and Puma proteins are found in developing mouse hair follicles and are involved in more than just cell death.
research Hair growth promoting activity of discarded biocomposite keratin extract
Keratin extract from human hair was found to promote hair growth in mice.
research HAIR AND SYSTEMATIC DISEASE
Hair loss can indicate underlying systemic diseases and addressing these can sometimes reverse the hair loss.
research Clinical significance of dermoscopy in alopecia areata: analysis of 300 cases
Dermoscopy helps diagnose and manage alopecia areata by showing specific hair changes.
research Mutant laboratory mice with abnormalities in hair follicle morphogenesis, cycling, and/or structure: An update
The document concludes that mouse models are crucial for studying hair biology and that all mutant mice may have hair growth abnormalities that require detailed analysis to identify.
research Mimicking Hair Disorders by Genetic Manipulation of Organ-Cultured Human Hair Follicles
Scientists can mimic hair disorders by altering genes in lab-grown human hair follicles, but these follicles lack some features of natural ones.
research Do follicles matter? Testing the effect of follicles on hair cortisol levels
Hair follicles increase hair cortisol levels, so consistent hair collection methods are important.
research Putting the Human Hair Follicle Cycle on the Map
The research created a model to understand human hair growth cycle, which can help diagnose and treat hair growth disorders and test potential hair growth drugs.
research Analysis of the scalp of women with AIDS subjected to autopsy: epithelial, follicular, and immunologic aspects
AIDS may cause changes in the scalp that increase infection risk and hair loss.
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 DERMAL GLYCOSAMINOGLYCAN CONCENTRATION THROUGHOUT HAIR GROWTH CYCLE OF RATS
Glycosaminoglycan levels peak early in hair growth and decrease as the cycle progresses.
research Geometric classification of scalp hair for valid drug testing, 6 more reliable than 8 hair curl groups
A 6-group hair classification is more reliable for drug testing than an 8-group system.
research Female patients complaining about hair loss: documentation of defective scalp hair dynamics with contrast-enhanced phototrichogram
The study concluded that a special imaging technique showed women with hair loss have slower hair growth and a faulty hair replacement cycle.
research Deep Hair Phenomics: Implications in Endocrinology, Development, and Aging
A new tool can analyze hair to detect changes due to hormones, genetics, and aging.
research Hoxc13 mutant mice lack external hair
Hoxc13 gene is essential for hair, nail, and papilla development.
research Quantitative trichoscopic analysis of hair density in people attending tertiary care hospital – A cross-sectional study
Hair density decreases with age, especially in the 60s.
research Light scattering from human hair fibers
Researchers developed a new model for more realistic computer graphics rendering of hair by considering how light scatters on hair fibers.
research Elucidating penetration pathways into the hair fiber using novel microscopic techniques.
The conclusion is that substances can penetrate hair fibers through multiple pathways, including both the cell membrane complex and the non-keratinous parts.
research Determination of the cuticula thickness of human and porcine hairs and their potential influence on the penetration of nanoparticles into the hair follicles
Nanoparticles penetrate hair follicles better when their size matches the cuticula thickness.
research P171 : Trichoscopic findings in androgenetic alopecia and alopecia areata
Trichoscopy effectively diagnoses and assesses hair loss severity in androgenetic alopecia and alopecia areata.
research HAIR ANALYSIS FOR DRUGS OF ABUSE. PLAUSIBILITY OF INTERPRETATION
Hair analysis can detect drug use but requires careful interpretation due to its complexity.
