This study found that African and Caucasian hair contain the most lipids, and depletion of these lipids leads to less water retention and increased water desorption, with Caucasian hair showing improved breaking tenacity after lipid extraction.

This study found that reinforcing epoxy with short human hair fibers and glass micro-spheres improved its wear resistance, suggesting potential applications in products like brake shoes and pads.

In this study, tresses treated with pH 1.0 acid straightener showed better straightening but more damage to hair properties compared to those treated with pH 2.0.

In this study, researchers developed a regression model that reasonably predicts consumer-perceived hair breakage using various parameters such as hair smoothness, detangling forces, extensional strength, and hair density among Indian women.

This study aims to develop and evaluate herbal shampoo powder made from natural ingredients, focusing on its efficacy in removing debris and dandruff, enhancing hair development and shine, and strengthening and darkening hair. Results are not reported.

This paper reviews various techniques for measuring the physical and mechanical properties of human hair fibers, emphasizing their importance in developing effective cosmetic products.

This review evaluates the scientific literature on silicon supplements, noting that orthosilicic acid shows higher bioavailability, but emphasizes the need for further clinical studies on safety and efficacy.

This study observed significant differences in hair and cashmere properties among three goat breeds in Southwest China, noting better quality cashmere in Inner Mongolia cashmere goats and their crossbreed compared to Dazu black goats.

This research observed that men with shaved heads were perceived as more dominant, taller, and stronger than men with full hair, suggesting potential benefits in social perception.

This study found that concurrent administration of cycloleucine with ethionine prevented the weakening of wool fibers in sheep, whereas reduced glutathione did not have the same effect.

This research reported that a newly developed dually crosslinked gelatin-alginate-based hydrogel scaffold enhances mechanical strength, promotes corneal tissue regeneration, and reduces scarring in rabbit models, suggesting potential applications in corneal tissue engineering.

This study found that a new eco-friendly hair crosslinking method using visible light and non-toxic chemicals caused less damage and improved mechanical properties compared to traditional thioglycolic acid treatment.

This article examines challenges in the pharmaceutical supply chain during pandemics, highlighting issues like raw material sourcing and distribution delays, and suggests enhancements such as AI, blockchain, and public-private alliances to ensure stability and resilience.

In this study, a bleaching protocol was developed to evaluate hair repair products, revealing that K18® and Olaplex® improve hair brightness and lightness, with distinct impacts on hair fiber properties.

This review discusses the roles of distinct immune cell types in skin wound healing, highlighting findings from animal studies, but provides no new clinical results.

This study found that low-molecular-weight hyaluronate significantly improved the mechanical strength and elastic modulus of overbleached hair by enhancing hydrogen bond networks within keratin.

This study proposed a new standardized in vitro framework using human hair tresses to evaluate cosmetic hair product performance and found significant improvements in hair breakage, tensile strength, shine, volume, and frizz control compared to a control group without such changes.

In this study, researchers observed that even a single session of hair dyeing can damage hair fibers, with significant worsening of mechanical properties and protein composition after three or more consecutive treatments, emphasizing the need to consider the cumulative impacts of dyeing on hair health.

This study found that crosslinking buffalo gelatin with different methods can modify its properties and potential as a skin substitute, though double-crosslinking may increase immunogenicity slightly.

In this study, researchers reported that the application of refolded human K31 keratin protein significantly improved diameter, mechanical strength, and smoothness of chemically damaged hair after a single treatment.

In this randomized controlled trial, oral intake of the probiotic Latilactobacillus curvatus LB-P9 significantly improved hair luster, elasticity, and participant satisfaction in individuals with mild to moderate hair damage compared to placebo, without significant adverse effects reported.

This study found that the down-hair fibers of native goats in Turkey have similar characteristics to cashmere fibers, indicating potential for high-quality textile products as a substitute.

This study found that Platycladus orientalis flavonoids may reduce oxidative damage and slow melanin degradation in AGA-affected hair, improving its quality.

This study found that a novel nutraceutical supplement improved hair growth and strength in subjects with hair thinning compared to placebo, without reported side effects.

Hair can't be as strong as Rapunzel's because it's impractical to scale up due to defects.

In this study, reducing agents like ammonium thioglycolate, L-cysteine, and sodium sulfite in shampoo effectively decreased hair flyaway and frizz without causing damage, as no critical hair damage was observed in structural and tensile strength assessments.

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 found that fibromodulin significantly reduces scar formation and boosts scar strength in rodent and porcine models, suggesting potential for FMOD-based therapies in cutaneous wound repair.

This study found that bleached hair showed optimal protein structural integrity and tensile strength at pH 5, with significant changes in cross-linking, water content, and diameter at more alkaline or acidic levels.

This study found that reinforcing clayey soil with human hair fibers increased its strength significantly, both before and after freeze-thaw cycles, suggesting its potential use in cold climate zones.
