This study found that thermal hair-straightening devices significantly damaged the cuticle and cortex of virgin Asian and Caucasian hair, with Asian hair experiencing more protein loss than Caucasian hair.

In this study, researchers found that the naked (N) gene in mice indirectly affects the synthesis of structural proteins in mouse hair, resulting in reduced high tyrosine protein content and unusual amino acid compositions.

This study found that keratin film from human hair samples responded to damage from UV, bleaching, perming, and thermal treatments, making it a useful model for evaluating hair damage in product development.

This study found that coconut oil impedes hair hydration more effectively than soybean oil by penetrating deeper, and suggested a new model for intermediate filament assembly in hair.

This review discusses the limitations of current hair classification systems and highlights the need for standardized reporting of key hair characteristics to improve study comparisons; it reports no new results.

This study found that the stability of the coiled-coil structure in human hair keratin is maintained by ion-pairing and hydrophobic interactions, which are disrupted as pH approaches 7.0.

The document explains how hair is studied in forensics to identify its source and its role in criminal investigations.

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.

This research explores the use of serial block-face scanning electron microscopy to model the complex architecture of sheep wool fibres, focusing on the role and distribution of para- and ortho-cortical cells in determining wool curliness, though the mechanism remains unclear.

This paper reviews various techniques for measuring the physical and mechanical properties of human hair fibers, emphasizing their importance in developing effective cosmetic products.

This study observed that in live rodents, actin filaments adjust their structure to facilitate membrane transfer between cellular compartments; linear filaments stabilize fused membranes, while branched filaments, connected by the protein Ezrin, drive integration, demonstrating actin's role in adapting to membrane biophysical changes.

This review discusses the significance of elastic tissue staining in dermatopathology, particularly for diagnosing primary elastic tissue disorders and other skin conditions, but reports no new clinical results.

This study identified the AtPRPL1 gene in Arabidopsis thaliana as being involved in cell elongation processes, despite unclear changes in cell wall composition from its altered expression.

This review discusses the impact of various exogenous agents on hair, such as cosmetics and radiation, but reports no new experimental results.

This review discusses the impact of various external factors like cosmetics, traction, and radiation on hair health and color, but reports no new findings.

This study found that CMAD wool keratin may protect human hair from damage during repeated bleaching and permanent waving treatments.

This study found that permanent wave treatment accelerates hair degradation after protease exposure, showing significant morphological differences compared to untreated hair and linked to damage from Alpha-helical region denaturation.

This study introduced mechanical setups to analyze the mechanical properties of root hairs in Arabidopsis thaliana, finding that axial stiffness primarily relates to tip compression and turgor pressure, confirmed by independent methods adapted from work on animal cells.

In this study, researchers developed innovative mechanical methods to measure the mechanical properties of Arabidopsis thaliana root hairs, concluding that axial stiffness is mainly due to tip compression and influenced by turgor pressure.

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 article reviews the potential hair-protective effects of Onion and Aloe vera against damage from hair dyes but reports no new experimental results.

This study found that repeated use of a protein hair conditioner, followed by hot air and gamma irradiation, may lower serum collagen I and increase heat shock protein concentrations in rats, suggesting potential cumulative risks.

In this study, carboxymethylalanyl disulfide keratin was shown to effectively prevent hair damage during repeated bleaching and permanent waving treatments.

Human hair's structure makes it tough and resistant to breaking.

In this review, the researchers highlight the role of fibroblasts in regulating the extracellular matrix and immune responses, emphasizing the impact on macrophages and potential therapeutic insights for fibrotic diseases and cancer.

This review explores how adult skin epithelia preserve stem cell populations for hair follicle regeneration and wound healing, but reports no new experimental results.

This review discusses advances in understanding hair and hair follicle structure, gene expression, and molecular signals in hair formation, without reporting new clinical findings.

This review examines hair cosmetics, including shampoos and conditioners, for their formulations and effects, but reports no new clinical findings; it emphasizes the importance of dermatologist knowledge in treating diverse hair conditions.

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 review summarizes the anatomical and physiological aspects of human hair and its clinical significance, but does not report new research findings.
