This study investigated the tensile response and morphological changes of different ethnic hair types using AFM, showing variations between virgin, chemically damaged, and conditioner-treated Caucasian hair under different conditions.

This study introduced a theoretical model suggesting that the morphological transition from bud to cap in tooth germ development is driven by mechanical interactions among cells.

This review discusses the role of polarity signaling in coordinating tissue mechanics, micro-environmental functions, and cell fate decisions, but it reports no new results, highlighting the need for further study in mammalian models.

This study introduced mechanical setups to analyze the mechanical properties of root hairs in Arabidopsis thaliana, finding that axial stiffness primarily relates to tip compression and turgor pressure, confirmed by independent methods adapted from work on animal cells.

This study found that the twisted hair shafts characteristic of pili torti may result from uneven outer root sheath cell development, leading to irregular hair shaft modeling and twisting.

In this study, both the Fox and modified Crawford frontalis sling techniques effectively improved ptosis and cosmetic appearance, with the modified Crawford technique resulting in less lagophthalmos.

Temporal triangular alopecia is a non-scarring hair loss seen in some Asian children.

This study used a 3D live imaging system to map cell dynamics in human hair follicles, revealing patterns of cell movement and division that help explain hair fiber extrusion during hair growth.

This study developed a universal ballistic trajectory model for unguided projectiles that considers both aerodynamics and altitude effects, showing comparable results to existing trajectory models and radar measurements.

This study revealed that frizzled 3 can fully rescue polarity defects in frizzled 6-null mice, while frizzled 6 can partially rescue defects in frizzled 3-null mice, highlighting conserved signaling roles in these proteins.

This study observed that human hair macrofibrils predominantly exhibit a double-twist architecture with varying inter-macrofibril angles, advancing insights into their structural organization and mechanical implications.

In ex vivo organ culture of human scalp hair follicles, this study found that IL-9 signaling inhibits hair growth, reduces progenitor cell generation, and disrupts immune privilege.

In this study, mathematical analysis suggested that a 30°-sapphire blade caused the least tissue injury during hair restoration, while a rectangular blade caused the most.

This study developed finite element models to examine skin's biomechanical properties, finding that structural heterogeneities like Rete ridges and hair follicles create distinct stress and strain patterns that may influence mechanosensation and skin integrity.

In this study, researchers found that the shape of polygonal domains, such as squares and triangles, significantly impacts Turing pattern formation, with domain geometry affecting the stability and type of bifurcations observed in simulations.

This case report describes the first recorded instance of congenital triangular alopecia in the mid-frontal scalp region, challenging the assumption that it is restricted to the frontotemporal area.

This study conducted in situ tensile loading experiments with atomic force microscopy to observe how conditioning treatments affect the tensile response of virgin, chemically damaged, and mechanically damaged Caucasian hair.

In this case study, an 18-year-old woman's triangular alopecic patch diagnosed as temporal triangular alopecia was considered non-progressive and had no impact on her quality of life, so no treatment was initiated.

This case report describes a 17-year-old girl with telogen effluvium and severe hair loss following a suspected COVID-19 infection and a history of similar episodes since childhood.

In this study, researchers developed vegan exosome-like vesicles from microalgae that mimic mammalian exosomes, demonstrating promising in vitro, ex vivo, and clinical effects such as improved wrinkle depth and elasticity, making them a potential alternative in cosmetic applications.

In this study, exosomes from hypoxia-conditioned mesenchymal stem cells significantly improved SOCS3 and STAT3 expression in a mouse model of androgenetic alopecia, suggesting they may offer a more effective therapeutic approach than minoxidil by restoring follicular homeostasis.

This study highlights exosome-based therapies as promising treatments for androgenetic alopecia, detailing protocol development, quality control measures, and clinical application examples, with mesenchymal stem cell-derived exosomes improving hair density in a case study without adverse effects.

This study evaluated the safety and efficacy of Bio-Pulsed avian mesenchymal stem cell-derived small extracellular vesicles when applied topically, finding significant improvements in hair growth, skin rejuvenation, and regenerative microRNA presence among 60 human participants without adverse events.

Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.

This study introduces the multiple papillary centres model, offering a new explanation for hair twisting by combining known hair morphology features with differential growth rates caused by dermal papillae.

This study analyzed the nanotribological properties of various hair types and human skin, revealing differences in friction and adhesion based on ethnicity and hair condition.

This review discusses prevention, diagnosis, and treatment strategies for traction alopecia but presents no new clinical findings; the authors emphasize early intervention to prevent permanent hair loss.

In this study, researchers developed innovative mechanical methods to measure the mechanical properties of Arabidopsis thaliana root hairs, concluding that axial stiffness is mainly due to tip compression and influenced by turgor pressure.

This study found that the weak tensile strength of pili torti hair may result from loose keratin intermediate filaments due to abnormalities in disulfide bonds.

This study reports a case of traumatic anserine folliculosis in a young male, where treatment with topical retinoids and keratolytics combined with avoiding friction significantly improved symptoms after nine months.
