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 miR-124 may facilitate the differentiation of hair follicle stem cells into neuronal cells by targeting Sox9 and Ptbp1.

This study found that arrector pili muscles formed by Sonic Hedgehog signaling play a critical role in maintaining sympathetic nerve connections to hair follicle stem cells, influencing hair regeneration, with implications for hair loss treatments.

This review explores the potential of metal nanoparticles as innovative treatments for alopecia, highlighting their effectiveness in promoting hair regrowth, enhancing drug delivery, and modulating gene expression while also assessing the related experimental methodologies and regulatory considerations.

This study found that micro-current electrical stimulation may promote hair growth in human hair follicle-derived papilla cells and a mice model by enhancing cell proliferation, migration, and activating key growth pathways.

This commentary discusses the challenges of matrix effects in LC–MS analysis and introduces the concept of a matrix effect factor using stable isotopically labeled internal standards to improve analysis reliability.

This study investigated the dynamic mechanical properties of fluid-immersed elastic hair beds under oscillatory shear flows, revealing a nonlinear response influenced by driving frequency and amplitude, which impacts mechanosensory signaling stability in biological processes like vasodilation and ciliary remodeling.

This article reviews the regulation of gene expression and assembly of intermediate filaments but presents no new findings.

This study identified new geometric and mechanical parameters for curly and kinky/coily hair, which may inform more effective personal care products tailored to these hair types.

This study found that Carbon Quantum Dots effectively detected and quantified Co²⁺ ions and methylcobalamin in tap water with high sensitivity and recovery rates between 95% and 105%.

This study introduced a method to isolate and separate microfibrillar proteins from human hair, identifying previously undetected glycine- and tyrosine-rich proteins.

The document concludes that human astrocytes aid stroke recovery, research confidence affects student career aspirations, collagen affects cancer spread, a microRNA suppresses brain cancer growth, calmodulin regulates water channels, and small magnesium pieces deform differently.

In this study, researchers observed that after mesenchymal cell division in mouse and chicken embryonic skin, elevated migration speed and persistence for 180 minutes contribute to mesenchymal dispersal and preferential recruitment to dermal condensates.

This study found that mechanical and chemical interactions in skin organoids are crucial for initiating mesenchymal-epithelial interactions necessary for hair follicle regeneration.

This study found that minoxidil sulfate stimulates Cl channels, potentially depolarization-activated and outwardly rectifying, in eccrine clear cells, while minoxidil itself stimulates Ca-insensitive K currents.

This study found that stem cell factor combined with fibronectin and type IV collagen promotes migration of amelanotic melanocytes, which may help explain their movement during vitiligo repigmentation.

This study found that laser ablation-inductively coupled plasma-mass spectrometry can effectively reconstruct time-resolved mercury exposure in micrometer segments of a single hair strand from fish-eaters.

In this case report, a 13-year-old girl with Pitt-Hopkins syndrome developed hair curling after starting the antiepileptic drug perampanel, which had not been previously reported as a side effect.

This study reported that both gray and black-brown hair had decreased sulfur content after dyeing with a permanent hair dye mixture consisting primarily of carbon, oxygen, nitrogen, and sulfur.

This study found that Florida manatees have unique types of specialized nerve endings in their vibrissae, which assist in their sensory and manipulative functions in aquatic environments.

D-chiral biomaterial scaffolds enhance tissue and hair regeneration by activating the body's immune system.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

This study found that human dermal papilla cells are surrounded by a basement membrane-like extracellular matrix, which maintains their aggregated structure without strong cell‒cell contacts.

In this study, fibronectin coating on a low-adhesive substratum increased cell aggregation, growth, and motility, enhancing the formation of hair follicle dermal papilla spheroids.

This study found that an increased calcium/magnesium ratio in hair and lower chromium concentration were associated with higher insulin resistance in Korean adult males.

This study concluded that Polyquaternium-10 conditioner softens the surface of the scale face on hair fibers.

Hair can't be as strong as Rapunzel's because it's impractical to scale up due to defects.

This paper explores the diverse patterns and social significance of Black hair, approaching it as an art form, mathematical pattern, and ethnomathematic entity, and seeks to dispel myths while highlighting its vast possibilities.

This research found that heavy metal concentrations of arsenic, lead, cadmium, and iron were significantly higher in human hair samples from 100 years ago compared to today's levels in southern Poland, with a median decrease of 69–95%.
