In this study, FN-based fiber scaffolds designed using Rotary Jet-Spinning were shown to enhance wound healing and reduce scar formation in a mouse model, suggesting potential for regenerating healthy skin structure.

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 found that cationic surfactant-based conditioning systems significantly reduce friction on hair fibers, improving wet and dry combability by forming a stable film layer on the hair’s surface, as verified by both instrumental and sensory evaluations.

In this study, researchers identified a three-step process underlying age-related curved hair from cyclical extension: surface lipid transfer, specific disulfide bond cleavage, and unraveling of α-helices into β-structures, which may inform care strategies to manage hair curvature.

This study found that lipid extraction increased water diffusion in wool and hair fibers; the effect was more pronounced in hair, indicating lipids are crucial for water permeability.

This study found that K33A was significantly upregulated in lustrous Magra wool follicles, while other keratin and KAP genes showed downregulation, impacting wool's physical properties like luster.

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.

Keratosis Follicularis Spinulosa Decalvans is a rare genetic disorder causing skin and hair issues, often inherited through the X chromosome.

This study developed an improved reference genome for the African spiny mouse using long Nanopore sequencing reads, potentially aiding future research into the species' remarkable tissue regeneration capabilities.

This study found that cationic surfactant-based conditioning systems significantly improve hair combability by forming a stable low-friction film on hair surfaces, reducing friction and enhancing sensory performance compared to standard systems, as confirmed by both instrumental and sensory evaluations.

In this study, a mechanical model was developed to describe and validate the effectiveness of overnight hair curling, suggesting that combining it with hair fixatives can maintain a desired curl for over a day.

This study found that spermidine, a polyamine, plays an essential role in hair growth in sheep follicles, while spermine is not required for normal follicle function.

This study found that Magra sheep with high-luster wool exhibited significantly higher expression of keratin genes, suggesting that increased keratin protein levels may be crucial for wool luster.

In this study, transfection experiments showed that mutations in the K85 gene affect filament formation with K35, which may impact hair formation related to ectodermal dysplasia.

In this study, researchers observed that the combination of hair progenitors and their micro-niche changes every three days in mouse zigzag hair, and disruptions in specific genes affected this rhythm, highlighting the importance of this periodic change for normal hair morphology.

This study examined hair from a mixed-heritage family and suggested that variations in pigment formation significantly influence hair form, including the occurrence of twist-knots.

This study analyzed the swelling behavior of human hair during permanent waving treatment, finding that both the microstructure and macrostructure of intermediate filaments swell simultaneously at the initial stage, and while partially destructed by reduction, they are considerably restored through oxidation.

This study found that electrospun short fibrous sponges effectively mimic the 3D extracellular matrix, promoting tissue regeneration, angiogenesis, and wound healing in diabetic rats better than 2D fiber membranes.

This study developed a double-wavelength laser scanning microphotometer to measure hair shaft and follicle absorbance, improving spatial resolution and reducing light scattering effects in vitro.

This study found that for straight hair, friction mainly influences fragment formation during combing, suggesting no direct connection to tensile fatigue failure, while with textured hair, combing performance may be more complex.

This opinion from the EFSA Panel concludes that the health claim regarding spermidine prolonging the anagen phase of the hair cycle does not meet regulatory criteria as it is related to disease treatment.

In this study, researchers found a significant decrease in the modulus of elasticity of hair shafts in premature neonates compared to full-term ones, potentially due to differences in disulphide bonds or microfibril arrangement.

This review re-examines hair blowouts as a material science process, where water acts as a plasticizer altering keratin's glass-transition temperature, allowing for temporary hair shaping through a moisture-induced matrix state change under heat and tension.

This research observed that 3D electrospun micro/nanofibrous sponges, without using chemical crosslinking agents, supported enhanced cell growth, vascularization, and skin regeneration in diabetic rats compared to 2D fiber membranes, making them promising for 3D tissue regeneration.

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

This study found that the viscosity of silicone oil in hair treatments significantly affects wave curling performance and hair damage, with untreated and chemically treated hair showing different optimal viscosities.

In this study, researchers mapped cysteine accessibility in wool keratins and KAPs, revealing that certain cysteines in keratin end domains and Types I and II rod domains are accessible and likely involved in forming disulfide bonds.

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.
