In this study of Angora goats, researchers found that HOXC13 and other genes were overexpressed during the active hair growth phase, suggesting a role in mohair structure.

This study found that HOXC13 gene expression was significantly higher during the anagen phase in Angora goats, potentially contributing to the mohair's shiny and silky nature.

This study found considerable variation in hair shaft proteomic profiles among Caucasian, African-American, Kenyan, and Korean subjects, with individual and site-specific differences observed.

This study used proteomic profiling to reveal significant individual and site-specific differences in human hair shaft proteins, which may improve the differentiation of hair based on ethnic origin and individual identity.

This study found that microfibrils play a crucial role in shaping permanent waves by thioglycolic acid, and treating damaged hair with hydrolyzed keratin improved both waving efficiency and hair damage.

This study found that extracellular factors from a specific developmental stage can promote hair follicle neogenesis in adult skin by facilitating interactions between fibroblasts and keratinocytes.

This chapter reviews the potential of adipose-derived stem cells for skin aging and hair loss treatments but reports no new experimental results; the authors highlight these stem cells as a promising regenerative resource.

This study found that αvβ6 integrin inhibits keratinocyte proliferation during wound healing and hair regeneration, suggesting its downregulation may enhance recovery and influence epidermal stem cell behavior.

This review discusses the role of cholesterol homeostasis in hair follicle biology and its potential connections to various hair disorders, but it reports no new findings.

This study reports that polyphenols from Annurca apples may safely promote hair growth and protect against chemotherapy-induced alopecia without interfering with chemotherapy regimens.

This study reports that scalp biopsies in white adults usually have 16.5 hair follicles, primarily in the anagen phase, with male samples showing fewer follicular units but more fibrous tracts in certain areas.

Mutations in the hHb6 gene cause the hair disorder monilethrix.

The document explains the genetic causes and characteristics of inherited hair disorders.

In this study, BTP-loaded solid lipid nanoparticles were developed and shown to protect hair from heat-induced damage by enhancing cuticle integrity and thermal resistance in simulated thermal straightening conditions.

This review discusses potential cosmeceutical treatments for hair loss, including ingredients like procyanidins and isoflavones, but does not present new clinical outcomes; the authors highlight the promise of further research.

This article discusses the characteristics of human hair, its damaging processes, and the potential repair effects of immuno-cosmeceuticals, but it reports no new clinical results.

Keratin 17 is important for hair and nail structure and affects pachyonychia congenita symptoms.

In this study, researchers evaluated the binding of keratin-associated proteins and α-keratins to human hair fibers, finding that chemical preactivation significantly enhanced binding to natural hair, while perming altered binding characteristics and increased penetration depth.

This study found that tryptophan fluorescence in natural white hair is significantly weaker than in other unpigmented keratin fibers, possibly due to greater environmental UV exposure or unknown chemical interactions.

This study demonstrated that urea significantly accelerates the diffusion of poly(ethylene imine) into bleached human hair by increasing the diffusion coefficient twofold.

This review identifies cysteine's central role in hair growth and its potential impact on Alopecia Areata's pathogenesis, suggesting examination of cysteine metabolism might clarify the disease's underlying mechanisms and lead to new treatments.

This review discusses various forensic applications of hair analysis, such as species identification and drug addiction testing, and reports no new study results.

In this study, a herbal mixture (RAA) was found to promote hair growth in mice, showing increases in hair density and follicle size similar to minoxidil treatment.

In this study, researchers developed a novel periodate oxidation method for extracting keratin micro-units from waste hair and feathers, achieving yields of 31.28% and 20.64% respectively, enhancing the stability of oil-in-water emulsions and suggesting potential for sustainable biomaterial production.

This study suggests that the mechanical robustness of hair may be enhanced by the binding interactions of keratin-associated proteins, particularly KAP8.1, with intermediate filament proteins.

This study reports that structural abnormalities in the inner root sheath of hair follicles may cause the hair shaft to be loosely attached in patients with loose anagen hair syndrome.

In this study, treatments using a shampoo and conditioner with hematin helped repair damaged hair by depositing a cuticle-like structure, straightening hair as observed through electron microscopy.

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 article discusses loose anagen syndrome, highlighting its characteristics, diagnostic methods, and spontaneous improvement over time, but provides no new clinical results.
