research Faculty Opinions recommendation of Live imaging of stem cell and progeny behaviour in physiological hair-follicle regeneration.
Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.
research Transient treatment response of platelet-rich plasma injection for temporal triangular alopecia: A case report with dermoscopic examination follow-up
PRP injections are not effective for long-term treatment of temporal triangular alopecia.
research Hormonal profile and androgen receptor study in prepubertal girls with hypertrichosis
Prepubertal girls with hypertrichosis have more sensitive androgen receptors, leading to increased body hair growth.
research Naevus trichilemmocysticus – the first paediatric case of a newly delineated organoid naevus
The first pediatric case of naevus trichilemmocysticus was documented.
research Dermoscopy to the rescue
Dermoscopy helps accurately diagnose and treat benign skin cysts.
research 840 Early and late matrix progenitors form the terminally differentiated cell layers of the hair follicle
Early and late matrix progenitors in hair follicles create different cell layers, with early ones forming the companion layer and later ones forming the inner root sheath and hair shaft.
research Trichoscopy – a valuable tool for identifying conditions mimicking androgenetic alopecia
Trichoscopy helps tell apart other hair loss conditions from common hair loss.
research Hair and nail disorders
Hair and nail disorders can cause changes in scalp pigmentation, especially with sun exposure and alopecia.
research Trichoscopy as an evaluation method for alopecia areata treatment: A comparative study
Trichoscopy is useful for diagnosing and monitoring alopecia areata treatment.
research Immunolocalization of telomerases in human hairs identifies proliferating cells in the bulb matrix and outer root sheath
Telomerase-positive cells are mainly in the bulb matrix and outer root sheath of hair follicles.
research Mapping of a novel locus for keratosis follicularis squamosa on chromosome 7p14.3–7p12.1
A new gene location for Keratosis follicularis squamosa was found on chromosome 7p14.3-7p12.1.
research Trichodystrophies: A hair-raising differential diagnosis
The guide helps doctors diagnose hair problems by suggesting a thorough patient history, physical exams, and various diagnostic tools.
research Induction of hair follicle neogenesis with cultured mouse dermal papilla cells in de novo regenerated skin tissues
Scientists successfully grew new hair follicles in regenerated mouse skin using mouse and human cells.
research VEGF induces proliferation of human hair follicle dermal papilla cells through VEGFR-2-mediated activation of ERK
VEGF promotes hair follicle cell growth through the VEGFR-2/ERK pathway.
research Dermoscopic and Histopathological Correlation in Cicatricial Alopecias: Unveiling Diagnostic and Therapeutic Insights
Trichoscopy effectively diagnoses and monitors cicatricial alopecias, reducing the need for biopsies.
research Multiplex matrix network analysis of protein complexes in the human TCR signalosome
Alopecia areata patients show unique protein activity patterns, suggesting imbalanced signaling pathways.
research TGF‐β2 is specifically expressed in human dermal papilla cells and modulates hair folliculogenesis
TGF-β2 plays a key role in human hair growth and development.
research Prostanoid receptors in anagen human hair follicles
Human hair follicles contain a complex network of prostanoid receptors that may influence hair growth.
research Single-cell sequencing combined with spatial transcriptomics reveals the characteristics of follicle-targeted inflammation patterns in primary cicatricial alopecia
Specific immune cells and pathways contribute to hair follicle inflammation and hair loss, suggesting potential treatments for lichen planopilaris.
research Cytochemistry of Trichohyalin Granules: A Possible Role for Cornification of Inner Root Sheath Cell in the Hair Follicle
Trichohyalin granules help inner root sheath cells in hair follicles harden by integrating with keratin filaments.
research What is ‘normal’ hair?
Normal hair thickness varies by scalp area and a mix of hair thicknesses is typical in healthy individuals.
research The trichoscopic features of hair shaft anomalies induced by epidermal growth factor receptor inhibitors: A case series
EGFR inhibitors often cause dry, brittle hair and eyebrow/eyelash changes.
research Cryopreservation of Multicellular Spheroids Derived From Rabbit Dermal Papilla Cells
research Cicatricial Alopecia with Particular Trichoscopic and Histopathological Features
The document concludes that a woman has both Frontal Fibrosing Alopecia and Lichen Simplex Chronicus, a previously unreported combination of conditions.
research Horse hair follicles: A novel dermal stem cell source for equine regenerative medicine
Horse hair follicles could be a new source of stem cells for healing horses.
research Comparative Analysis of Trichoscopic Features in Women with Androgenetic Alopecia and Telogen Effluvium
FAGA shows varied hair thickness, while TE has more empty follicles.
research Overexpression of alkaline phosphatase improves the hair-inductive capacity of cultured human dermal papilla spheres
Increasing alkaline phosphatase in human skin cells helps to grow more hair.
research Case Report: Bi-allelic missense variant in the desmocollin 3 gene causes hypotrichosis and recurrent skin vesicles
A new genetic change in the DSC3 gene is linked to a rare condition causing hair loss and skin blisters in a child.
research Selective follicular targeting by modification of the particle sizes
Medium-sized particles penetrate hair follicles better than smaller or larger ones, which could improve delivery of skin treatments.
