research Circle Hairs in a Patient with Multiple Myeloma
An elderly woman with cancer improved after treatment for a rare skin condition with coiled hairs.
research Symmetry breaking of tissue mechanics in wound induced hair follicle regeneration of laboratory and spiny mice
Tissue stiffness affects hair follicle regeneration, and Twist1 is a key regulator.
research RETRACTED: Is photoshop with Qualitative Image Analysis a valid technique for measuring hair morphology? A test using wires of known dimensions
QIA-64 software can measure straight wire lengths accurately but needs improvement for curved wires and width measurements.
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 Adverse reaction to isotretinoin: alteration of the hair shaft structure
Isotretinoin can rarely cause hair to grow curly.
research Formation of surface membranes in developing mammalian hair fibres
Mature hair surfaces are formed by keratinized cells with developed layers, not just modified plasma membranes.
research Hair Keratin
research A novel cosmetic approach to treat thinning hair
A new hair treatment with caffeine and other ingredients makes hair thicker and less likely to break.
research Alteration in Hair Texture Following Regrowth in Alopecia Areata
Alopecia areata caused a boy's hair to regrow straight instead of curly, but the exact reason is unknown.
research The heart of the hair fiber: How the inner structure of the coat reflects adaptive variation across color, sex, age, and body region in dromedary camels (Camelus dromedarius)
Camel hair structure, not color, helps camels stay cool in the desert.
research 614 Humanized mouse model for hair follicle studies
Researchers successfully used nude mice to study human hair growth, which could help with future hair research.
research Histological characteristics of hair follicle pattern in Indian bison (Bos gaurus), black buck (Antelope cervicapra) and nilgai (Boselaphus tragocamelus)
Indian bison, black buck, and nilgai have distinct hair follicle patterns useful for species identification.
research Hair Loss Physiology and Transplantation Principles
Hair loss is caused by hormonal changes that shorten hair growth phases and shrink hair follicles.
research Hair trace elementary profiles in aging rodents and primates: links to altered cell homeodynamics and disease
research High-voltage Electron Microscopy and 3-D reconstruction of human hair fiber ultrastructure
The research provided a detailed view of the non-keratinous parts of human hair fibers.
research 877 Small T antigen from a folliculotropic polyomavirus activates canonical Wnt/β-catenin signaling in vivo
A virus protein can activate a pathway that may lead to abnormal hair follicle development.
research Tumors of the follicular infundibulum
Benign tumors from hair follicles can look like other skin cancers but have distinct features under dermoscopy.
research 839 Spatiotemporal antagonism in mesenchymal-epithelial Signaling in sweat versus hair fate decision
Sweat glands and hair follicles are determined by opposing signals, with BMPs promoting sweat glands and blocking BMPs leading to hair follicles.
research Development of a novel, clinically-relevant model for investigating factors that stimulate human hair growth
Testosterone stimulates growth in intermediate hair follicles, but this can be blocked by cyproterone acetate.
research Hidradenitis Suppurativa/Acne Inversa/Dissecting Terminal Hair Folliculitis
Hidradenitis Suppurativa is a chronic skin condition best treated early with surgery for better outcomes and less recurrence.
research The Catalog of Human Hair Keratins
Human hair is made up of different keratins, some strong and some weak, with specific types appearing at various stages of hair growth.
research Water distribution in human hair microstructure elucidated by spin contrast variation small-angle neutron scattering
The technique showed that human hair has two main parts, with 68% being rigid and the rest flexible, and water swelling affects its structure.
research Effect of cyproterone acetate on rate of hair growth in hirsute females
Cyproterone acetate reduced hair growth in most hirsute females and made hair softer, thinner, and lighter.
