research A Morphometric and Histologic Study of the Scalp in Psoriasis: Paradoxical Sebaceous Gland Atrophy and Decreased Hair Shaft Diameters Without Alopecia
Psoriasis on the scalp causes smaller oil glands and thinner hair but doesn't lead to hair loss.
research The Lanceolate Hair Rat Phenotype Results from a Missense Mutation in a Calcium Coordinating Site of the Desmoglein 4 Gene
A gene mutation causes lanceolate hair in rats by disrupting hair shaft integrity.
research In Vivo Reflectance Confocal Microscopy: Usefulness for Diagnosing Hair Diseases
In vivo reflectance confocal microscopy is useful for evaluating hair shaft diseases but needs improvement for deeper hair follicle issues.
research Hair Morphology in Androgenetic Alopecia
Abnormal cuticle and hair shaft medulla cause hair loss in androgenetic alopecia; sonography helps diagnose and manage it.
research Bubble Hair
Bubble hair deformity may be caused by hair shaft trauma and can improve with gentle hair care.
research Analysis of DNA in Hair Fibers
Small amounts of DNA can be found in the hair shaft, especially near the root, but it decreases with hair treatments and washing.
research A Case of Acquired Trichorrhexis Nodosa After Applying New Hair Spray
New hair spray caused a hair shaft disorder.
research 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 Expression Pattern of mTOR Subunits Raptor and Rictor in Mouse Hair Follicle Cycle
Raptor and Rictor have stable expression in hair cycles, with Raptor marking stem cells and Rictor involved in hair shaft formation.
research Skin And Hair On-A-Chip: In Vitro Skin Models Versus Ex Vivo Tissue Maintenance With Dynamic Perfusion
The Multi-Organ-Chip improves the growth and quality of skin and hair in the lab, potentially replacing animal testing.
research Conditional Disruption of Hedgehog Signaling Pathway Defines Its Critical Role in Hair Development and Regeneration
The hedgehog signaling pathway is crucial for hair growth but not for the initial creation of hair follicles.
research Effects of Sex Steroid Deprivation and Administration on Hair Growth and Skin Sebum Production in Transsexual Males and Females
Hormone treatments in transsexual individuals reduce hair growth and oil production in male-to-females and increase them in female-to-males.
research A Hot New Twist to Hair Biology: The Role of TRPV1 in Human Hair Growth Control
Capsaicin, found in chili peppers, can slow down hair growth by affecting skin cells and hair follicles.
research The Dermal Papilla: An Instructive Niche for Epithelial Stem and Progenitor Cells in Development and Regeneration of the Hair Follicle
The dermal papilla is crucial for hair growth and health, and understanding it could lead to new hair loss treatments.
research Micro-RNA-31 Controls Hair Cycle-Associated Changes in Gene Expression Programs of the Skin and Hair Follicle
miR-31 regulates hair growth by controlling gene expression in hair follicles.
research Dlx3 Is a Crucial Regulator of Hair Follicle Differentiation and Cycling
Dlx3 is essential for hair growth and regeneration.
research Human Scalp Hair Follicles Are Both a Target and a Source of Prolactin, Which Serves as an Autocrine and/or Paracrine Promoter of Apoptosis-Driven Hair Follicle Regression
Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.
research Hair Shafts in Trichoscopy
Trichoscopy is a useful non-invasive method for diagnosing different hair loss conditions.
research Developmental Timing of Hair Follicle and Dorsal Skin Innervation in Mice
Nerve growth in mouse skin and hair follicles happens in stages and is closely linked to hair development.
research Human Hair Keratin Network And Curvature
Curly hair shape is due to uneven growth patterns in the hair follicle.
research Hair Growth Promoting Effects of Adipose Tissue-Derived Stem Cells
Fat tissue stem cells may help increase hair growth.
