This report highlights a case where dermoscopic observation of corkscrew hairs in a young woman led to the diagnosis of trichotillomania, emphasizing its role in distinguishing this psychiatric disorder from other forms of non-scarring alopecia and highlighting the importance of timely intervention.

This study found that SK2 channels in sensory terminals of rat muscle spindles and hair follicles may play a crucial role in modulating mechanosensory transduction by influencing receptor potentials through Ca2+-activated K+ currents.

This study suggests that the KAP 7 gene may serve as a potential molecular marker for genetic selection to improve staple length and greasy fleece weight in Rambouillet sheep.

This study found that overexpression of an enzyme in transgenic mice led to distorted polyamine levels, resulting in permanent hair loss and female infertility.

This study found that a conditioner containing 18-MEA and SPDA can improve hair's smoothness and reduce flyaways, enhancing hair manageability.

This study found that trichoscopy can diagnose genetic hair shaft abnormalities without plucking or cutting hair, by visualizing characteristic features in a single session.

In this study, the bending stiffness of human hair was linked to the varying proportions of para-like versus ortho-like cortical cells within the hair fiber.

This abstract provides no results; it is a website notification about cookies and general access to JAMA content.

This study suggests that corkscrew hairs in tinea capitis result from internal hair damage by Trichophyton violaceum and external resistance from scalp scales.

This study found that targeting the hair follicle can be increased by using lipophilic drugs combined with surfactant solutions and propylene glycol.

This study examined the role of long non-coding RNAs in wool fineness among Gansu alpine fine-wool sheep, identifying specific lncRNAs and target genes that may enhance wool quality.

In this study, the authors concluded that the TS-associated polyomavirus may disrupt Wnt/β-catenin signaling, likely contributing to abnormal hair follicle formation in trichodysplasia spinulosa.

This study found that DNA strand segregation in multipotent hair follicle stem cells occurs randomly during development and tissue homeostasis, challenging the immortal strand hypothesis.

This study identified a new FAK isoform, FAKΔe4, which is regulated by ECM stiffness and affects cell migration, invasion, and mechanosensing in human-derived data and engineered models.

This study found that low massage frequencies like 4.2 Hz enhance nanoparticle penetration into hair follicles more effectively than higher frequencies, indicating potential applications in therapeutic and cosmetic delivery.

This study found that massaging hair treatments into hair improved the treatment's effectiveness by reducing hair waviness and enhancing shape cohesion.

This study describes the development of polyamide 6 composite fibers with amber filler, finding them suitable for use in medical textiles such as compression garments due to their biocompatibility with skin cells.

This review discusses in vitro methods for evaluating the effects of hair care products on hair fibers, reporting no new results; the authors emphasize the importance of selecting appropriate and accurate equipment for testing.

This study found that Super Merino sheep have a higher wool follicle density, finer fleece, and distinct gene expression compared to Small Tail Han sheep, which may inform future breeding and genetic interventions.

Centrifugal forces can help prepare hair follicle germs for hair regeneration.

This study analyzed the nanotribological properties of various hair types and human skin, revealing differences in friction and adhesion based on ethnicity and hair condition.

In this study, oral spermidine supplementation was found to significantly prolong the hair follicle anagen phase and reduce hair loss, with effects persisting three months after treatment in healthy participants, suggesting potential therapeutic benefits for hair loss conditions.

This study demonstrated that dyeing can enhance the absorption coefficient of hair follicle tissues for selective photodestruction within human skin and hair follicles.

This case report describes a family with autosomal dominant transmission of keratosis follicularis spinulosa decalvans, with observed treatment refractoriness in multiple topical and systemic therapies.

This review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

This study introduced a noninvasive spectroscopy method to assess hair follicle stages in mice by measuring skin diffuse reflectance and melanin dynamics, offering a potential tool for hair regeneration research.

This study investigated the effect of peracetic acid treatment on hair fiber structure and found that disulfide bond oxidation altered thermal properties while preserving the α-crystal structure, suggesting different stabilizing interactions in hair fibers.

This systematic review concludes that trichoscopy is a reliable diagnostic tool for trichotillomania and should be incorporated into standard clinical practice for differential diagnosis.

This paper introduces a novel approach to simulate hair dynamics by modeling hair volume as a continuum, effectively treating interaction dynamics as fluid dynamics for realistic hair animation rendering.
