This study found that 53% of Japanese women have straight hair while 47% have varying degrees of curved hair, with distinct structural differences observed in the internal makeup of curved hair fibers.

This case report suggests that melanin, as an energy generator, may offer a new perspective on studying and treating autoimmune disorders such as alopecia areata.

This study reports pseudopili annulati in a dark-haired Chinese girl, identifying the unique appearance and structural characteristics of her hair without finding abnormalities in the cuticle and cortex.

This study discovered a conserved "fiber-like-motif" of melanosomes aligned in hair across various mammalian species, shedding light on the internal structure that influences hair's thermal and mechanical properties.

This study used theoretical calculations to show that phosphates strongly bind to cerium dioxide surfaces in various stable configurations, with spectral signatures identifiable in the infrared and Raman spectra, informing future experimental efforts in controlling the enzymatic activity of ceria nanoparticles.

This study found that endothelin-1 increases adhesion and chemotaxis of amelanotic melanocytes on fibronectin, laminin, and collagen IV, potentially through changes in the actin cytoskeleton.

This study examined hair curvature in Japanese women, finding that 47% have curved hair, and identified structural differences in hair fiber, which resemble those in wool fibers.

In this study, researchers used iron ion coordination to successfully create a molecular knot with three organic ligand strands and eight crossings.

In this study, NuMA's microtubule-binding domain was found to be crucial for correct spindle orientation and skin differentiation, with its loss leading to neonatal lethality in mice.

In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.

This study found that Finasteride may spontaneously diffuse into an SDS-based model cell membrane at a significant rate, with distinct behavior in polar and non-polar solutions.

In this study, higher concentrations of environmental metals, particularly manganese, were linked to worse self-reported attention-related behaviors in adolescents from Italy, with no significant modification of this effect by iron status.

This study reported that MRI-based ovarian morphology shows significant overlap between PCOS cases and controls, highlighting the need to consider clinical and biochemical data alongside imaging findings for PCOS diagnosis.

This study found that Cupiennius salei spiders have specialized mechanosensitive hairs on their legs that adaptively respond to joint movements during walking, suggesting a proprioceptive function.

This study found that biologic rhythms in mammoth hairs differed from those in modern human hair, with variations in growth rates and mineral content providing insights into the lifestyle and behavior of extinct species.

This study quantified the effects of chemical treatments like oxidative bleaching and hair relaxing on the movement characteristics of hair strands using a novel high-speed recording method.

This article discusses the role of external beam radiotherapy as a primary treatment method for cancer and reports no new clinical findings.

Keratin fibers in hair twist left-handed.

This study reports that electromagnetic energy from a hydrocolloid wound dressing paste adversely affected human skin lipid droplets in vitro, but the implications, including potential cancer links, are unknown.

Children with autism have different levels of certain metals and elements in their hair and blood, affecting symptoms.

This study found that patients with androgenic alopecia had altered neuroactive steroid levels and depression symptoms after stopping finasteride treatment, suggesting lingering neuropsychiatric effects.

This study found that a conditioner containing 18-MEA and SPDA can improve hair's smoothness and reduce flyaways, enhancing hair manageability.

The study improved understanding of keratin fiber structure by showing consistent microfibril diameter but varying distances and electron density profiles.

This study found that exposure to Prussian Blue caused significant detachment of cuticle segments from the hair shaft in both new and aged human hairs.

This study's simulations suggest that biomechanical factors, like follicle geometry and tissue stiffness, are likely significant in hair fiber protrusion, providing a framework for future experimental validation.

A teenager's hair with alternating white and dark bands, known as Pili annulati, is a genetic condition that is usually harmless and often considered attractive.

Human stem cells can aid stroke recovery, research experiences boost students' career aspirations, minoxidil may reduce cancer spread, a molecule can slow tumor growth, a protein affects water flow in cells, magnesium behaves differently at tiny scales, and a new method detects slow-moving objects.

This study suggests that varying intersheet interactions may explain the differences between the two polymorphic forms of macrofibril assembly in Merino wool and hair.

Low-dose pulsed electric fields in a rat model shifted hair follicles from resting to active growth, with voltage as the most influential factor.
