This study suggests that while some evidence indicates potential efficacy of placental products for hair growth and inhibiting hair loss, the current scientific evidence is scarce and of low quality.

Scientists made nanoparticles from human hair proteins to improve drug delivery.

The Beverly Hills Diet is unhealthy and can cause serious health issues; pharmacists should advise against it and asthmatics should avoid nonprescription antihistamines.

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

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 study reveals that overexpression of Wnt3 in transgenic mouse skin leads to a short-hair phenotype and cyclical balding due to structural defects in hair shafts, highlighting a role for WNT signaling in hair growth regulation.

This review discusses the role of TGF-β signaling in stem cell recruitment and tissue regeneration, indicating that abnormalities in TGF-β activation contribute to various major diseases and suggesting avenues for therapeutic intervention.

This study found that Wnt signalling activates hair follicle fate in hair follicle stem cells by relieving TCF3/4–TLE-mediated repression, with β-catenin being crucial for this process.

This review discusses the immune roles of keratinocytes in wound healing and chronic wound inflammation, emphasizing their potential impact on chronic wound pathology and highlighting areas for future research.

This study observed that keratose, derived from human hair, integrated well in mouse tissue and remodeled with collagen, suggesting potential as a non-toxic biomaterial for regenerative applications.

This study characterized keratin-based biomaterials that self-assemble into hydrogels, demonstrating their potential to achieve hemostasis in a lethal liver injury model through specific biomaterial-receptor interactions.

This study found that a new topical nitric oxide gel significantly accelerated burn wound healing in mice by enhancing re-epithelialization, hair follicle regeneration, collagen deposition, and angiogenesis compared to controls.

This article discusses how drug molecules integrate into hair fibers, focusing on biological transport mechanisms and physicochemical factors, but reports no new experimental findings.

This review discusses the potential role of extracellular vesicles in modulating hair follicle dynamics and reports no new clinical results; future investigations may inform treatment strategies for skin disorders.

This study found that Krtap11-1 may play an important role in keratin-bundle assembly in the hair cortex, influencing the physical properties of hair.

In this study, experimentally induced weight loss in merino sheep led to a decrease in wool fiber diameter and increased expression of certain high sulfur and glycine-tyrosine proteins, potentially impacting wool quality and industry preferences.

This study indicates that the Sp6 gene is crucial for the development of skin, teeth, limbs, and lungs in mice, possibly through regulating apoptosis.

This study suggests that human keratin fiber matrix has a well-defined nano-scale grainy structure rather than being amorphous, with grain size influenced by chemical treatments, temperature, humidity, and follicle-level factors.

In this study, the identification of a novel KAP gene in sheep, named KRTAP36-1, was associated with increased prickle factor in wool, suggesting its potential as a genetic marker for breeding purposes.

Hair can indicate early signs of metabolic disorders, with issues like protein deficiency stopping hair growth.

In human follicular cells, this study found that an Annurca apple-based dietary supplement may stimulate the production of hair keratins, suggesting potential benefits for hair growth.

This study suggests that specific combinations of human type I and II hair keratins, particularly K35-K85 and K36-K81, have distinct in vitro assembly properties that are significant for macrofibril formation.

This study identified a human sequence likely coding for a new ultra-high sulphur protein, which may aid in understanding hair differentiation and the molecular basis of human trichothiodystrophy.

This study found that while both natural and bioengineered salivary glands showed similar protein concentrations in response to taste stimulation, their protein compositions and amylase concentrations differed, which may affect nerve signal balance.

The method effectively analyzes human hair proteins, especially nonfilamentous ones.

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.

This study found that growth in rats hindered by thyroid removal at birth can be normalized through the administration of thyroid preparations like thyroxine and artificial thyroprotein.
