In this study, Raman micro-spectroscopy did not support the hypothesis of structural changes in hair follicles due to miniaturization in women with androgenetic alopecia.

This study found that keratins have evolutionarily conserved and domain-selectively enriched amino acids, which likely reflect their unique structural roles, with distinct patterns observed among epidermal, hair, and simple-type epithelial keratins.

This review discusses the diversity of keratins and keratin-associated proteins in wool and hair, noting significant variation in their families, with no new results reported; the authors detail known protein structures without experimental findings.

This study reports that immunologically inert and skewed immune cell populations in developing human skin may contribute to wound healing and structural changes during skin development.

This study found that wool felting in Ukrainian Carpathian Mountain sheep is linked to significant changes in fatty acid composition, particularly highlighting a decrease in 18-methyleicosanoic acid in bound lipids, suggesting it as a potential marker for cuticle lipid layer damage during felting.

This study found that piglets' rapid growth during nursery and lactation was linked to changes in microbiota composition and increased cortisol conversion, highlighting critical early life factors influencing adult microbiota establishment.

This study fabricated a polyamide fiber containing amber particles and characterized its potential for textile applications, noting that the chemical structure of amber remained unchanged after grinding and integration.

In this case study, a 38-year-old woman with female androgenetic alopecia experienced increased hair density and improved hair structure following ten microneedle mesotherapy sessions combined with saw palmetto supplementation, without adverse effects.

This study purified trichohyalin protein from pig tongue epithelium, characterizing its unique properties and structure, which may facilitate future functional research.

This study found that improved protein extraction methods enhanced the resolution of hair proteins on gels, but differences in protein abundance between curly and straight Japanese women’s hair were minimal and unlikely to affect hair structure.

This study found that the mechanical stiffening of the human hair follicle along the first millimeter is linked to changes in the keratin network architecture and composition during keratinization.

This study observed that transgenic mice expressing keratin K10 under bovine K6beta control developed severe oral abnormalities, suggesting keratin composition changes can affect the physiology of epithelial cells, especially in the oral mucosa.

This study observed that in Assam Hill Goats, the primary hair follicles had larger diameters and more structural associations compared to secondary follicles, especially in ruminant-age groups.

This article reviews the use of hair analysis in forensic and environmental toxicology for detecting potentially toxic elements and drugs, but it reports no new research findings.

This review discusses the role of keratins in maintaining epidermal structure and function and reports no new results; the authors emphasize the lack of rational therapies for skin disorders linked to keratin mutations.

This article discusses the potential for targeted therapies in hair loss by exploring inflammatory and cytokine-mediated processes, but it presents no new clinical results.

This review discusses the role and therapeutic potential of mesenchymal cell-derived exosomes in organ development and disease treatment, highlighting their application in cell-free therapeutic strategies and current challenges faced in their use.

In this pilot study, topical latanoprost acid was observed to increase hair count and improve hair follicle structure in women with androgenetic alopecia, with no serious adverse events, suggesting potential for further investigation to confirm its efficacy and safety.

This review discusses the immune functions of porcine skin and proposes a classification of dendritic cell subsets based on similarities to human skin, but it reports no new clinical results.

This review assessed a traditionally prepared herbal hair oil, finding it exhibited favorable physicochemical properties and stability, with no skin irritation, suggesting it may be a safe natural alternative to synthetic hair care products for promoting healthy hair and scalp.

This review highlighted the potential benefits of herbal hair oils as a natural alternative to synthetic hair care products, noting that a traditionally prepared formulation demonstrated favorable physicochemical properties and no skin irritation, while promoting healthy hair and scalp.

This article reviews the roles and synthesis of essential long-chain fatty acids in the body and reports no new research findings; it emphasizes the importance of dietary sources for these lipids.

In this review, the authors provide a comprehensive overview of Equisetum arvense (horsetail) as a promising natural ingredient in cosmetics, highlighting its antioxidant, anti-aging, anti-inflammatory, and wound-healing properties, while also noting challenges related to standardization and clinical validation.

This review examines the use of horsetail extract in cosmetics, highlighting its antioxidant, anti-aging, and skin-enhancing properties due to its rich phytochemical content, but notes that standardization and clinical validation remain challenges.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

This review discusses the anatomical and histological characteristics of facial fat compartments and reports no new clinical results, emphasizing a need for further research on their role in facial aging.

In this study, the researchers identified the specific subcellular localization of the protein S100A3 in the endocuticle and cortex of human hair shafts.

This study revealed that in androgenic alopecia, the proximal attachment of the arrector pili muscle to the hair follicle is often lost or significantly reduced.

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 review discusses various forensic applications of hair analysis, such as species identification and drug addiction testing, and reports no new study results.
