This study found that in Japanese, German, and American females, changes in hair lipid patterns with age may reflect alterations in sebum excretion and affect hair texture.

This study found that scanning electron microscopy with argon sputter etching visualizes hair lipids at the cell membrane complex as distinctive convex structures, shedding light on their role and localization in human hair.

Some oils can penetrate hair and reduce the stickiness between fibers, but mineral oil cannot.

This study investigated the penetration of a low-molecular-weight cationic conditioning compound into the hair cortex and suggests it may improve hair's fatigue resistance.

This study found that the uptake of molecules by hair is influenced by both hydrophobic and ionic charge interactions, with binding affinity decreasing as pH approaches the solute's dissociation constant.

In this review paper, the authors explored the composition and role of lipids in human hair, highlighting their importance for hair texture, moisture retention, and tensile strength, while noting that the understanding of hair lipids' functions remains controversial and requires further research.

This review reports on the effects of aging on hair characteristics such as pigmentation, growth, and structural properties across genders and ethnicities, highlighting the importance of scalp health and suggesting cosmetic solutions to improve the appearance of aged hair.

This review discusses various microneedle technologies for long-acting drug delivery, highlighting design considerations and challenges in bringing these minimally invasive devices to market, but it reports no new clinical results.

This study examined argan oil inclusion complexes with β-CD, finding that these complexes improve the antibacterial efficacy, uniformity, and mechanical performance of hair treatment formulations while enhancing the durability of bleached hair, suggesting their potential as stable and effective cosmetic ingredients.

In this study involving South African breast cancer patients, researchers identified certain genetic variations in cytochrome P450 and other enzymes potentially linked to differences in tamoxifen treatment outcomes, suggesting a need for more comprehensive pharmacogenomic studies to optimize therapy in African populations.

This study reports that hair damage from bleaching is associated with the oxidative cleavage of fatty acid thioester bonds, detectable by measuring the decrease in mass spectrometry peak at m / z 76.

This study observed that keratose, derived from human hair, integrated well in mouse tissue and remodeled with collagen, suggesting potential as a non-toxic biomaterial for regenerative applications.

This study found that PCL-based nanofiber scaffolds enhanced cell proliferation and extracellular matrix deposition, suggesting they show promise as a cell delivery system for improving skin wound healing.

This study concluded that polymeric nanoparticles effectively targeted hair follicles for drug delivery, but the organogel formulation did not enhance their penetration into the hair shaft.

This study found that arginine-loaded lipidic nanoparticles improved hair follicle growth in male hamsters more effectively than an aqueous arginine solution.

This study observed that congenital hypotrichosis in crossbred cattle is linked to short, curly, dilute-color hair, potentially due to color dilution mutants in European breeds.

In this study, forming inclusion complexes of Finasteride and poly (ethylene glycol) resulted in significantly improved solubility and dissolution rates, suggesting a promising new solid form for enhanced drug release.

This article reviews the use of the Nd:YAG laser for hair removal and reports no new research findings.

In this study, NREs from lentil root nodules, specifically Serratia plymuthica 33GS and Serratia sp. R6, significantly enhanced lentil growth, altered root exudation, and modulated rhizospheric microbial communities in a greenhouse setting.

This study introduced RoPod, a customizable tool for low-stress live imaging of Arabidopsis roots, which improves data reproducibility and provides new insights into plant autophagy by revealing detailed, cell type-specific responses to chemical modulators.

In this study, a bleaching protocol was developed to evaluate hair repair products, revealing that K18® and Olaplex® improve hair brightness and lightness, with distinct impacts on hair fiber properties.

This paper reviews the surface degradation of hair and describes how combining 18-MEA with specific surfactants can maintain hydrophobicity on bleached and weathered hair surfaces.

This study reports that the asebia-2J mutation in mice affects sebaceous gland function and leads to hair follicle destruction, offering a model for human scarring alopecias.
