This study explored how silicones influence the interaction between hair fibers and their impact on hair volume under high humidity conditions.

This study found that hair germ cells, derived from bulge stem cells, respond faster to dermal papilla signals and have limited proliferation compared to bulge cells during hair regeneration.

Hair follicles form hard α-keratin filaments in four steps, showing structural differences.

This study used rapid-freezing immunocytochemistry to successfully map the ultrastructural localization of hair keratins in human scalp hair, primarily finding them in macrofibrils in the cortex and endocuticle.

This review discusses the role of tissue mechanics and extracellular matrix in skin aging processes and highlights potential therapeutic strategies, but reports no new clinical results.

This paper reviews keratoacanthoma as a tumor that resembles but rarely progresses to squamous cell carcinoma, detailing its stages, potential origins, and distinguishing features from other similar growths, without reporting new clinical results.

This study reported that albino Wistar rats exposed to chemical hair straighteners showed significant hair fiber damage and scalp skin deterioration, which worsened with repeated and prolonged application, highlighting the cytotoxic potential of these products and potential systemic risks.

In this study, researchers found that chemical treatments like bleaching can cause severe damage to the hair cuticle, with previously modified hair showing complete deterioration compared to the partial degradation seen in virgin hair, highlighting the need for mindful cosmetic practices.

This review discusses the impact of endocrine-disrupting chemicals on pediatric health, linking them to various disorders, and calls for improved biomonitoring strategies and precautionary policies.

This study examined wool traits in Angora rabbits using low-coverage whole genome sequencing, identifying six QTLs and a gene, FGF10, linked to fiber growth and diameter, suggesting a cost-effective approach for complex trait analysis in genomic breeding.

This study analyzes contemporary theories and practices to understand key factors influencing the development of the examined phenomenon, proposing trends and practical applications for researchers and practitioners, while acknowledging study limitations and suggesting future research directions.

Fungi-produced compounds can change plant root growth.

In this research, the authors identify coordinated mechanical forces as crucial for hair follicle development in mammals, with contractile, proliferative, and proteolytic activities facilitating the formation and sectioning of epithelial structures crucial for forming a functional tissue.

This chapter reviews cultural practices and morphological differences in ethnic hair, relating them to specific disorders seen in these populations, without presenting new clinical results.

This review highlights that hair's chemical bonds, particularly disulfide bonds, are not homogeneous, as previously thought, but instead vary in response to different cosmetic treatments, suggesting a need for further exploration of ionic bonds and hydrophobic interactions.

This study found that ethanolic leaves extract of Hibiscus rosa-sinensis L. exhibited strong antioxidant activity and enhanced wound healing properties in mice, showing reasonable safety in toxicological evaluations without severe alterations.

This study found that the ethyl acetate fraction of Hibiscus rosa sinensis petals significantly reduced serum glucose and glycated hemoglobin levels in diabetic rats, showing effects comparable to the standard drug metformin.

In this case study, a man's hair and nail symptoms, following dental treatments, resolved with mesalazine therapy after investigating suspected clindamycin allergy and diagnosing mucosal changes.

This analysis highlighted the importance of integrating scientific literacy into chemical hair procedures, emphasizing that understanding the interaction of chemical agents with hair's biological structure and making evidence-based decisions can improve safety, predictability, and professional standards in the beauty industry.

This review highlights the complex role of scientific knowledge and professional expertise in safely performing chemical hair procedures, emphasizing the importance of education to prevent potential adverse effects like hair damage and scalp irritation.

This review outlines the various fibroblast subsets in the skin dermis, their origins, and their influence on epidermal stem cell behavior, highlighting the role of the local dermal niche in stem cell plasticity.

This study presents a proof-of-concept for a hybrid electric vehicle power system using a high temperature PEM fuel cell as a range extender, which may offer increased energy density with a methanol/water fuel mix.

Hair growth is cyclic and influenced mainly by local factors.

This study identified gene expression patterns in a mouse model that may influence tumor susceptibility and tissue functions related to inflammation and cell proliferation, highlighting Lgr5 and the vitamin D receptor as key regulators.

This review discusses the causes and diagnosis of traction alopecia, emphasizing education for high-risk populations as there is currently no cure, and presents no new clinical findings.

This review highlights the need for methodologies to understand and quantify drug penetration into hair follicles as significant drug pathways, noting this area lacks comprehensive articles and reports no new results.

This study demonstrates that FMOD deficiency in mice alters TGF-β ligand and receptor expression during wound healing stages, leading to delayed wound closure and increased scar size.

This study suggests that human keratin fiber matrix has a well-defined nano-scale grainy structure rather than being amorphous, with grain size influenced by chemical treatments, temperature, humidity, and follicle-level factors.

This study found that laboratory-formulated natural shampoos condition hair better than commercial herbal shampoos, as shown by SEM micrograph analysis of hair microstructure.

This overview highlights an increase in nonsurgical cosmetic procedures and a growing number of male patients seeking cosmetic treatments, without reporting new clinical results.
