This study found that keratin-based particles were able to recover and enhance the mechanical properties and thermal stability of virgin and overbleached Asian hair, improving its strength and smoothness by around 40%, and demonstrated safety in human skin keratinocytes.

This study describes a method to extract and characterize keratin particles from human hair, finding they can encapsulate the anticancer drug Paclitaxel with significant efficiency, releasing it in a pH-dependent manner potentially beneficial for targeted cancer treatment.

This review discusses the effects of protein-based cosmetics on hair properties and reports no new research findings, suggesting potential benefits for developing advanced, sustainable hair products.

This study extracted water-soluble keratin particles from chicken feathers and verified their structural properties, observing no irritative potential on hen's eggs and positive physiological effects on human skin cells, suggesting their suitability for use on damaged or irritated skin.

In this study, researchers extracted soluble keratin proteins from chicken feathers and found they maintain structural integrity with potential uses for damaged skin, exhibiting no irritative effects in ex vivo settings on hen's eggs.

This study observed that keratin-based microspheres promoted hair regrowth in C57BL/6 male mice and enhanced hair growth markers in human dermal papilla cells, suggesting these particles may effectively target hair follicles to aid in hair growth.

This study suggests that keratin peptide signatures in human hair shafts could potentially be used to distinguish gender and ethnicity, though further research on a larger scale is needed.

This study suggests that keratin peptide signatures in human hair shafts may potentially be used to distinguish gender and ethnicity, although further validation with larger samples is needed.

This study demonstrated potential in using specific keratin peptide profiles from human hair shafts to distinguish gender and ethnicity, suggesting it could enhance forensic investigations, though larger studies are needed.

This study found that the binding and release of BMP-2 from kerateine biomaterials are significantly influenced by pH and salt concentration, highlighting the potential for developing improved bone repair systems.

This review discusses the history and development of keratin biomaterials for biomedical uses, highlighting their biological activity and biocompatibility, and provides no new research findings.

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.

The wolves suspected of man-eating in the 1880s likely ate very little human flesh and mostly consumed a diet similar to herbivores and omnivores.

This review discusses the potential of protein-based cosmetics, including keratin-based particles and fusion proteins, to improve hair properties such as strength and shape, but it reports no new clinical results.

This study found that alkylation of kerateine cysteine residues created a cell-compatible method for controlling hydrogel erosion rates and therapeutic agent release in keratin-based systems.

This study found that medium-sized particles (643 and 646 nm) penetrated deeper into porcine hair follicles in vitro than smaller or larger particles, suggesting size-selective targeting within follicular sites.

In this study, particles similar in size to keratin cells were surprisingly found to penetrate more efficiently into hair follicles due to a possible pumping effect from moving hairs.

This study found that Cynatine HNS significantly improved hair and nail health in women after 90 days compared to placebo.

This study found that proteomic analysis can distinguish hair samples across different ethnicities and body regions based on keratin protein levels, which may aid forensic hair identification.

This review discusses hair straightening techniques, products, and safety risks, providing guidance for dermatologists to advise patients effectively; it reports no new clinical results.

This review discusses the structure and regenerative potential of hair follicles, highlighting their role in wound healing, stem cell populations, and keratin-based biomaterials, but it reports no new clinical results.

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 reports that human hair follicle stem cells express different surface markers than mouse stem cells, facilitating their isolation and potentially aiding in the development of cell-based skin treatments.

This study developed a multiscale model to understand human hair fiber mechanics and found that the yield stress decreases linearly with temperature, supported by both simulations and experimental stretching of hair fibers.

This review discusses the role of proteomics in understanding skin diseases such as cancers and psoriasis, with findings suggesting cell death and metabolism as major areas of focus, but reports no new experimental results.

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 identified differentially expressed proteins and pathways potentially involved in wool bending in Zhongwei goats, with specific genes like COL6A1 and CRNN emerging as important candidates in this process.

This study found that homocysteine-keratin accumulation in human hair increases towards the tips, linked to copper/iron-catalyzed demethylation of methionine, and may contribute to keratin damage.

Keratin could help create enamel-regenerating toothpaste in a few years.

This study identified and characterized progenitor cells from equine feet that may play a role in the pathogenesis and recovery of laminitis, suggesting potential therapeutic targets for treatment.
