Ethanol spreads well on hair at low humidity but less so at higher humidity due to water condensation.

This study suggests that sericin microneedles with antibacterial and directional traction functionalities may enhance infected wound healing by improving skin repair and inhibiting bacterial growth, indicating potential for clinical application.

This study describes a double embedding technique for preparing tangential sections of hair and wool fibers, recommending specific staining methods for quantitative analysis and demonstrating wool fiber cortical fractions.

This case report documents a rare association between atopic eczema and pili annulati in two siblings from north India, an unusual finding not previously reported in the literature.

This study used Raman spectroscopy and wide-angle X-ray scattering to observe two main α-helix to β-sheet transitions in hair keratin under varying humidity levels, finding that water impacts when these structural changes occur, involving a disordered state.

This study found that fibronectin nanofiber dressings, made using rotary jet spinning, accelerated wound healing and improved tissue restoration in a full-thickness wound mouse model.

This study reported advances in identifying low-abundance proteins in wool by using fractionation techniques to reduce the dominance of intermediate filament proteins, improving the understanding of the wool proteome.

This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.

This review explores the potential genetic and epigenetic influences on hair whorl patterns and suggests that pattern formation may involve basic physical-chemical laws, although it reports no new experimental findings.

This study found that individuals with protein-calorie malnutrition, especially those with kwashiorkor, required significantly less force to pluck hair compared to well-nourished patients.

This article reports no new clinical findings but discusses two rare dermatological conditions, trichostasis spinulosa and eruptive vellus hair cysts, and their simultaneous occurrence.

This study found that mouse hair follicle stem cells in a quiescent state exhibit greater chromatin dynamics and de-differentiation potential, suggesting higher cell fate plasticity compared to their proliferative or differentiated counterparts.

This study reported that a single treatment with a short-pulsed 755-nm alexandrite laser effectively treated trichostasis spinulosa in patients with skin types II to V, providing rapid results with minimal pain and no recurrence during a 3-month follow-up.

The study found that pili bifurcati causes hair to intermittently split into two branches, each with its own outer layer.

This case report describes the first confirmed instance of trichodysplasia spinulosa in a child with Down syndrome and leukemia, linking it to the TS-associated polyomavirus.

This study found that human hair follicles emit electromagnetic fields due to metabolic activity linked to S100 proteins, visualized using a novel microscopic technique with nano-sized iron particles.

This study found that women with alopecia have significantly lower tensile strength in both dry and wet hair samples compared to controls, indicating increased hair breakability.

This study described a new wig coating technique using keratin and graphene oxide that significantly enhanced UV resistance, antistatic properties, and durability compared to traditional methods.

This study found that the structural and chemical composition of human curly hair may resemble that of sheep wool, implying a shared characteristic among mammals with wavy hair.

This study found that permanent waving treatment partially disrupts the α-helical structure in human hair microfibrils, primarily during the initial reduction phase, rather than just affecting disulphide bonds.

This study found that the moisture content of human hair significantly influences the type of fracture under tensile loading, with low or high humidity levels leading to smooth fractures and intermediate humidity resulting in step fractures.

In this study, researchers found that the protein Twist2 plays a crucial role in scarless wound healing in early embryonic mouse skins, with its knockdown leading to visible scarring and defective hair follicle formation, suggesting potential therapeutic targets for reducing scars and promoting regeneration.

A simple method can show hair's surface pattern.

This study clarified and quantified the concept of hair transparency using a validated mathematical model based on measurable hair properties and consumer perception data from stylists in Japan and China.

This review discusses pili torti, a rare hair shaft disorder, and reports no new clinical results; it emphasizes the need to investigate underlying conditions in affected individuals.

This review discusses the flexibility and diversity of tissue stem cell systems, particularly focusing on the motility and ligand distribution of spermatogenic stem cells, without presenting new experimental results.

In this study, researchers identified specific gene polymorphisms in Subo Merino sheep that significantly affect wool traits, suggesting these genetic markers could aid in breeding high-quality fine-wool sheep.

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.

This study identified five distinct natural scalp whorl patterns and noted that White males have more distinct whorls, whereas African Americans and women often display a diffusion pattern.
