research 1334 Beyond goosebumps: Interactions between the hair follicle, the arrector pili muscle, and the sympathetic nerve during development and hair follicle regeneration
Arrector pili muscle regulates hair follicle stem cells, DNA methylation needed for hair cycling, and Wnt/B-catenin signaling starts hair growth.
research Ugreelig hår
A young boy's uncombable hair is due to a rare genetic condition that usually improves over time.
research A case of pili torti in a young adult domestic short-haired cat
A young cat had a rare hair condition with twisted hair shafts but stayed healthy.
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 Wigs and hair prosthetics
Wigs and hair prosthetics boost confidence and quality of life for people with hair loss.
research Hair Casts
Hair casts may be caused by repetitive hair pulling or styling and are often misdiagnosed.
research Isolated hair loss on the eyebrow: five cases with trichoscopic features
Trichoscopy helps tell apart hair loss due to alopecia areata from trichotillomania in eyebrows.
research A Missense Mutation within the Helix Termination Motif of KRT25 Causes Autosomal Dominant Woolly Hair/Hypotrichosis
A mutation in the KRT25 gene causes woolly hair and hair loss.
research Hair Vibrissa Follicle Morphogenesis is Linked to the Expression of Retinoic Acid Receptors α and γ Genes
Retinoic acid receptors are important for hair follicle development.
research Induction of follicle formation and hair growth by vibrissa dermal papillae implanted into rat ear wounds: vibrissa-type fibres are specified
Implanted dermal papillae can induce hair growth in rat ear wounds.
research A highly sensitive MEMS silicon‐hair device reproducing the function of hair follicle
The device mimics human hair follicles and detects tiny forces and moments with high sensitivity.
research Pathogenesis in pili torti: morphological study
Pili torti hair twists due to uneven outer root sheath cell development.
research Morphogenesis of the Hair Follicle during the Ontogeny of Human Skin
research Cyclical dermal micro-niche switching governs the morphological infradian rhythm of mouse zigzag hair
Mouse zigzag hair bends form due to a 3-day cycle of changes in hair progenitors and their environment.
research Comparative aspects of the inner root sheath in adult and developing hairs of mammals in relation to the evolution of hairs
The inner root sheath evolved to help hair grow safely through the skin in mammals.
research Characterization of hair lipid images by argon sputter etching-scanning electron microscopy
Hair texture changes with age due to varying levels of lipids.
research Analyzing the laser-light reflection from human hair fibers. I. Light components underlying the goniophotometric curves and fiber cuticle angles.
The research found a way to measure hair surface changes by analyzing how light reflects off of it, and determined hair cuticle angles vary by hair length and color.
research Keratin formation in the hair follicle
Keratin fibrils in hair form and stop growing at specific points in the follicle.
research Expression Profiling and Cellular Localization of Genes Associated with the Hair Cycle Induced by Wax Depilation
Researchers found new genes involved in hair growth, which could help develop new hair treatments.
research Loose anagen hair syndrome: take a closer look!
The girl's hair condition improved on its own in 24 months.
research Hair and Scalp Disorders
Alopecia areata causes patchy hair loss, and certain hair features can suggest its presence.
research Hair follicle associated pluripotent (HAP) stem cells jump from transplanted whiskers to pelage follicles and stimulate hair growth
Stem cells from whiskers can be transplanted to stimulate hair growth.
research A Raman spectroscopy investigation of the resilience of hair cuticular scales under uniaxial stress
Hair cuticles remain stable and resilient under stress due to strong protein content and crosslinking.
research The Effect of Hydration on the Mechanical Behaviour of Hair
research Loose anagen hair syndrome
Loose Anagen Syndrome is a hair condition where hairs can be easily pulled out, mainly affecting young girls, and may improve on its own or with treatment.
research Towards a Better Physical Understanding of Human Hair : Development of Fiber Tribology-Methods at the Micro- and Nanoscale
Polyquaternium-87 reduces hair friction the most among tested polymers.
research Hair Follicle Development and Hair Growth from Defined Cell Populations Grafted onto Nude Mice
research Le gènehairlessde la souris
The hairless gene is crucial for hair health, and its mutations cause hair loss.
research Robust coupling between the C‐tactile afferent and the hair follicle in humans
C-tactile nerves are sensitive to hair movement.
