This report describes a patient with symptoms suggestive of both loose anagen hair syndrome and uncombable hair syndrome, adding to previous instances of overlapping features between these conditions.

This study explored a mother and daughter with loose anagen hair syndrome linked to wooly hair, identifying an intronic variant in the KRT71 gene that affects hair keratin splicing, thus broadening the spectrum of KRT71-related disorders.

This paper discusses the role of Runx1 in epithelial biology and pathology, highlighting its dual function as a tumor promoter and suppressor in different contexts, and reports no new experimental findings.

This case study reported that after removal of an interstitial cell tumor from a ruffed lemur, the animal experienced improved coat quality and a return to normal behavior without signs of cancer spread.

This study mapped the curly mutation in mice to a specific region on chromosome 11, identifying it as a candidate model for studying human genetic hair disorders.

This study observed that hair follicle cuticular cells undergoing keratinization were significantly thicker than those in a normal hair shaft, due to incomplete loss of cytosol.

This review explores the structure and development of the hair cuticle, highlighting difficulties in studying some aspects and proposing new experimental approaches, but reports no new clinical results.

This study investigated the mechanical response of the human hair cuticle to strain and found that cuticular deformation directly corresponded with fiber elongation, revealing significant molecular-level changes in disulfide crosslinks but maintained structural stability, highlighting the role of the cuticle in stress resistance.

This study observed defects in hair cuticle cross-linking in some, but not all, mouse mutants with sparse or structurally unsound hair.

This study suggests that the cell membrane complex in hair cuticles contains hydrophilic regions with disulfide bonds allowing polymer uptake and hydrophobic lamella-like lipid layers.

Mouse tail skin has different keratinization near hair follicles and scales.

This study proposed the existence of a membrane-like structure between the cuticle and cortex in human hair, which may provide strong protection against external stimuli.

This study suggests that reptilian claws grow differently from mammalian claws, with continuous epidermal growth rather than a proximal matrix zone for cell proliferation.

This study found that defective cross-linking in hair cuticles is observable in a minority of mouse hair mutants, suggesting different proteins are involved in cross-linking across cell types.

This study reports that flaky skin mice exhibit skin and nail features that closely resemble human psoriasis vulgaris, suggesting they may serve as a natural model for this condition.

This study details the presence of two types of cysts in rhino mouse skin, with utricles derived from hair canals and deeper cysts from hair root sheath epithelium.

This article describes the structure and components of hair cuticle cells and their intercellular junctions but reports no new clinical results.

This study reports pseudopili annulati in a dark-haired Chinese girl, identifying the unique appearance and structural characteristics of her hair without finding abnormalities in the cuticle and cortex.

Zinc deficiency causes early scalp hair damage that recovers slower than skin symptoms.

This study found that a highly resistant structure, located at the interface between the cuticle and cortex of human hair, acts as a penetration barrier, which the authors propose to name the "cuticle anchored resistant base" or CARB.

This study found that keratin filament networks in SG1 cells of mice undergo dynamic changes during cornification, impacting the barrier function of the stratum corneum.

This study observed that particles sized 300-600 nm penetrate hair follicles more efficiently, likely due to alignment with the thickness of the human hair cuticula.

This case report describes an 18-year-old woman with a pruritic rash featuring extensive confluent scaly erythema, hyperkeratotic follicular plugging, and waxy keratoderma on palms and soles.

This study found that repeated cycles of wetting and blow-drying hair fibers can cause cracks in the hair cuticles, particularly among individuals who frequently blow-dry their hair.

This study found that the formation of the fibre cuticle surface in Merino sheep is similar to the epidermal stratum corneum process and not from a modified plasma membrane as previously thought.

This study explored the structure and keratin composition of marsupial hairs, finding similarities in keratin localization to hairs in placental mammals, and highlighting potential roles of trichohyalin and transglutaminase during hair development and shedding.

This study found that the weak tensile strength of pili torti hair may result from loose keratin intermediate filaments due to abnormalities in disulfide bonds.
