This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.

This study found that keratin 6hf, a type II keratin, is expressed in specific regions of mouse and human hair and suggests potential interactions with keratin 17, impacting hair development and associated disorders.

This study suggests that Keratin 6hf may be a potential marker of oral squamous cell carcinoma and could play a role in its progression, though further research is needed to understand its function.

This study found that while most mice lacking MK6a and MK6b genes died from tongue epithelium disintegration, about 25% survived and showed no hair or nail defects due to a newly discovered MK6hf gene.

This study found that coculturing human hair follicle keratinocyte stem cells with dermal papilla cells increased expression of the hair-specific keratin 6hf gene, which requires β-catenin/lef-1 signaling for hair differentiation.

This study found that a keratin mutation may cause diffuse partial woolly hair associated with loose anagen hair syndrome in some families, but other genetic factors could play a role in different cases.

This study found that loose anagen hair syndrome is a common form of alopecia in young girls, typically presenting with thin, sparse hair and usually confirmed by a hair-pull test.

This article reviews the causes and clinical presentation of pseudofolliculitis barbae, highlighting how genetic susceptibility and hair removal practices contribute to its development, but reports no new research findings.

This study found that hair follicle-specific keratins can form different structural assemblies depending on ionic conditions, with hair cortex keratins requiring physiological salt conditions to form intermediate filaments.

This article discusses the characteristics and pathogenesis of pseudofolliculitis barbae, particularly its prevalence in men of African and Asian descent, but presents no new research findings.

Razor bumps are linked to a genetic variant, misoprostol helps erythromelalgia pain, steroid ointments don't affect skin rhythms, and certain antibodies are common in localized scleroderma.

The document concludes that various treatments, including laser therapy, are effective for managing pseudofolliculitis barbae, especially in darker skin types.

This study found that androgens inhibit hair follicle stem cell differentiation by disrupting the Wnt signalling pathway in dermal papilla cells, but Wnt activation can restore differentiation.

This review discusses the diagnostic criteria and guidelines for managing loose anagen syndrome and differentiating it from non-scarring alopecias, but it reports no new clinical results.

This case report observed that a 2-year-old girl with loose anagen hair syndrome experienced rapid and significant improvement without adverse effects from tapered minoxidil 5% treatment over 28 months.

This review discusses the complexity and genetic organization of human keratin gene clusters and addresses the ongoing need for an updated unified naming system; it reports no new clinical results.

Loose anagen hair syndrome in children may improve with age, but treatment results vary.

A Saudi girl was diagnosed with Loose Anagen Hair Syndrome, a rare condition causing easy hair loss without scarring.

This review summarizes the cell type distribution and functional significance of human keratins, emphasizing their roles in tumor diagnosis and potential clinical applications, and reports no new clinical findings.

This review discusses the role of keratins in epithelial cell stress protection and cancer, highlighting their potential as multifunctional regulators and diagnostic markers, without presenting new research findings.

This review discusses advances in understanding hair and hair follicle structure, gene expression, and molecular signals in hair formation, without reporting new clinical findings.

This study found that Cutl1 mutant mice experienced retarded lung differentiation and abnormal hair follicle morphogenesis, indicating the vital role of CDP in lung development and hair follicle cell-lineage specification.

This review discusses the advancements in intraoperative stem cell therapies and highlights their potential to improve hair regrowth, but it reports no new clinical results.

This study found that a topical hedgehog agonist can stimulate hair growth by promoting the transition from the resting to growth phase of the hair cycle in adult mouse skin.

This review discusses keratin disorders and potential RNA interference therapeutics, reporting no new clinical findings but highlighting the promise of siRNA for future treatments.

This review discusses the molecular mechanisms of androgens and androgen receptors in skin disorders, particularly androgenetic alopecia, and reports no new clinical results; it highlights potential areas for future treatment development.

This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.
