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 reports that the mechanical interactions between human skin and adjacent subcutaneous white adipose tissue influence the appearance of skin wrinkles, with sWAT reinforcement potentially more effective for reducing signs of skin aging than skin reinforcement alone.

In this study, the researchers conducted tensile tests on individual curly human hair fibers sourced from a female donor and found distinct mechanical properties under various conditions, including different strain rates and temperatures, both dry and in saline immersion.

Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.

This study suggests that mechanical stress may influence androgenic alopecia patterning through a stretch-induced and androgen-mediated mechanotransduction mechanism in dermal papilla cells.

This study found that the tensile strength of curly hair is influenced by two main components, with springiness (toe region) contributing significantly, unlike in noncurly hair where it is negligible.

This study found that frequent attenders at Cork University Hospital's emergency department accounted for a disproportionate amount of visits and were more likely to require admission for further care.

This study characterized the stress-strain properties of the human scalp and found that its stiffness increases significantly with load, providing valuable insights for planning scalp surgery procedures.

This mini-review highlights emerging themes on how tissue stiffness, a fundamental material property, influences morphogenetic processes in living organisms, an area gaining increased attention alongside the role of mechanical forces in shaping cell behavior.

This study suggests that age-related changes in skin elasticity reduce its stability against wrinkling, and anti-aging strategies should focus on addressing elastic mismatches between skin layers.

Human hair's structure makes it tough and resistant to breaking.

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 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.

This research concluded that the novel hydrogel PlacMA, derived from human placenta and curable by visible light, shows promise for cell culture and tissue engineering applications due to its tunable properties.

This review discusses recent advances in surface modification and endothelialization of biomaterials for vascular grafts, highlighting promising methods like gene engineering and targeting ligand immobilization to improve clinical outcomes.

This review discusses the potential of lecithin organogels for improving topical drug delivery and presents no new experimental results; the authors highlight their stability and low skin irritancy as advantages.

This study found that forming spheroids using silicone micro-wells improved the viability and neural differentiation potential of human adipose-derived stem cells after thawing.

This review discusses the effects of vacuum massage on skin structures and concludes that there is insufficient evidence for its efficacy in treating burn scars, suggesting more research is needed on its potential benefits and mechanisms.

This review explores the complex interrelationships among different properties of natural hair fibers and underscores the need for a holistic taxonomy to improve data interpretation across disciplines, but it reports no new experimental results.

In this study, researchers found that replacing natural aggregates with animal bones and human hair with increased microroughness may improve the mechanical strength and durability of concrete.

This review explores the regenerative potential of hair follicles and their role in complete skin regeneration, emphasizing the influence of mechanical factors and niche signaling pathways on hair growth and loss.

This review describes the use of carbon dioxide for aesthetic treatments like skin rejuvenation and scar reduction but does not present new clinical findings.

This study found that while yak belly hair is chemically similar to human hair, its higher porosity and lower mechanical strength limit its usefulness as a substitute in hair dye development.
