In this study, children's hair showed statistically higher elasticity than elderly hair, but no significant differences were observed in tensile strength between dietary or oil application groups, or between pigmented and nonpigmented hair.

This study proposed a network model for the cross-linked structure of keratin-associated proteins in hair and wool fibers, suggesting notable differences between the two, potentially affecting hair fiber elasticity.

This study identified two single-nucleotide polymorphisms and three haplotypes in the KRTAP7-1 gene across yak, taurine, and zebu cattle, with the BOVIN-KRTAP7-1*A haplotype most prevalent.

This study demonstrated that cryogelation of human hair keratin allows the development of 3D scaffolds with tunable properties, supporting cell adhesion and proliferation for potential biomedical applications.

This study found that stabilizing HIF1A in balding hair follicle cells shifted their metabolism towards glycolysis, reducing oxidative stress and potentially promoting hair growth.

Hair care practices like using relaxers and tight braiding can lead to permanent hair loss in black women.

This review discusses the cultivation techniques of Amla (Phyllanthus Emblica), highlighting its high vitamin C content and various health benefits, and emphasizes the importance of sustainable cultivation practices to meet increasing commercial demand.

This review discusses the causes and diagnosis of traction alopecia, emphasizing education for high-risk populations as there is currently no cure, and presents no new clinical findings.

This study observed that certain hair care practices, such as wearing cornrows and using hair extensions, were strongly associated with the development of traction alopecia and seborrheic dermatitis in African American girls.

This study demonstrated that keratin derived from human hair can improve axon extension and alleviate motor deficits from sciatic nerve injuries, highlighting its potential as a promising biomaterial for peripheral nerve regeneration.

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 reports that KCV and its palmitoylated derivatives show strong effectiveness in strengthening hair proteins, indicating their potential for use in advanced hair care products.

In this study, researchers found that the primary cause of slippage and detachment of keratin capsules in hair extensions is the re-contamination by oily residues from the hairdresser's hands, rather than the use of hair care products like masks or conditioners.

Certain skin drugs and topical agents, including some natural extracts and fragrances, can cause allergic reactions. Some hair dyes and extensions, as well as minoxidil, a hair growth treatment, can also cause allergies. Botulinum toxin A can effectively reduce sweat but may have temporary side effects.

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 review highlights the lack of research on Afro-textured hair, emphasizing the need for better understanding of its genetic traits and molecular structure to develop more effective hair care solutions.

This study investigated the effects of wool-derived hydrolysed keratin peptides on relaxed textured hair and found that mid- and high-molecular weight peptides improved mechanical strength and reduced breakage in different humidity conditions.

This study assessed the effects of chemical treatments on hair fiber integrity and found that conditioners with vegetable oils like jojoba and coconut enhanced hydrophobicity and reduced combing friction except for jojoba, while participants preferred these oil-containing conditioners over the base formulation.

This study found that novel thiol-reactive cross-linking agents, particularly APA, significantly improved the tensile strength and elasticity of human hair fibers by effectively regenerating disulfide bridges, with potential applications for advanced hair repair treatments in the cosmetic industry.

In this pilot randomized clinical trial, TRT combined with finasteride increased lean mass, muscle size, and bone mineral density without prostate enlargement in men with spinal cord injury, suggesting potential benefits for body composition and musculoskeletal health.

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.

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 study observed that while hair camouflage techniques can boost confidence and reduce stigma for Black women with alopecia, they can also contribute to further hair damage; clinicians should consider safer styling practices as part of individualized care strategies.

This study discusses how redox imbalance, specifically through reduced Insulin-like Growth Factor-1 mediated by the transcription factor JunB and sphingolipid metabolism changes, contributes to skin aging by depleting stem cell pools and altering the extracellular matrix, ultimately impacting skin integrity and function.

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 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.

This study found that ensemble machine learning models effectively predict hair fall by combining the strengths of individual algorithms, leading to higher accuracy, precision, and recall in identifying hair and non-hair fall instances compared to single algorithms.

This study indicated that while testosterone replacement in older men with low testosterone increases muscle mass and strength and reduces fat, its effects on physical function, disability, falls, or fractures remain unclear.

This study found that while MK-0773 significantly increased lean body mass in sarcopenic frail elderly women, it did not significantly improve muscle strength or physical function compared to placebo.
