This article reports electron microscope studies on the structure of hair and wool, but it does not present new clinical findings.

This article reviews the composition and structure of mammalian hard keratins, focusing on the filamentous and nonfilamentous protein content, and reports no new experimental results.

This study identified two high sulfur protein genes, B2E and B2F, in rats, which are expressed in hair cortical cells during anagen and contribute to hair fiber production.

This study identified numerous size polymorphisms in the human ultrahigh sulfur KAP4 genes due to intragenic sequence variations, suggesting these polymorphisms may have arisen through deletions and duplications during evolution.

In this study, two novel clusters of keratin-associated protein genes on human chromosome 11 were analyzed, suggesting their products are crucial for hair formation due to preferential expression in hair roots.

This study identified two evolutionarily conserved ultra-high-sulfur keratin proteins in human and sheep hair follicles, which are specifically expressed in the hair cuticle during the late stages of fiber development.

This study investigated the mechanical response of the human hair cuticle to strain and found that cuticular deformation directly corresponded with fiber elongation, revealing significant molecular-level changes in disulfide crosslinks but maintained structural stability, highlighting the role of the cuticle in stress resistance.

This review discusses the role of diet in managing hair loss during menopause and reports no new clinical results; it highlights the importance of nutrients like sulfur amino acids, vitamins, and minerals.

This study identified a human sequence likely coding for a new ultra-high sulphur protein, which may aid in understanding hair differentiation and the molecular basis of human trichothiodystrophy.

This study identified a domain on human chromosome 21q22.1 containing various high glycine-tyrosine and high sulfur keratin-associated protein genes, revealing their diverse expression in hair-forming cells.

Keratin-associated proteins are crucial for hair strength and structure.

This review discusses the role of mineral nutrients in human health, emphasizing the importance of dietary sources and education to prevent mineral deficiencies, and reports no new clinical results.

This study found that the S100A3 gene is exclusively expressed in hair follicle cells differentiating into hair shaft components in mice, suggesting its important role in hair formation.

This study identified a cluster of genes on chromosome 17 related to hair keratin-associated proteins, including 37 genes forming seven multigene families, localized in the hair shaft's upper cortex.

This study identified 16 novel high sulfur KAP genes and two KAP pseudogenes on chromosome 21q23, showing expression in a specific region of the hair fiber cuticle.

This study suggests that the keratins found in reptile and bird skin appendages evolved independently from mammalian hair keratins, highlighting convergent evolution in these species.

This study proposed a network model for the cross-linked structure of keratin-associated proteins in hair and wool fibers, suggesting notable differences between the two, potentially affecting hair fiber elasticity.

In this study, researchers identified several active metabolites in Eclipta alba, demonstrated strong interaction with Alzheimer's disease proteins, and found that 28 days of treatment improved memory without significant toxicity in rats, suggesting potential pathways for treating Alzheimer's.

This review highlights LTBP1 as a critical integrator in disease processes, showing its dual role in cancer progression and suppression, its pathological influence in fibrosis, and its contribution to various disorders, suggesting its potential as a biomarker and therapeutic target.

This study revealed that human keratin-associated protein genes are expressed in specific patterns in hair fiber regions and vary in size, with some variations distinct across different populations.

This study reports the cloning and sequencing of two type II hair-specific keratin genes, ghHb1 and ghHb6, located on chromosome 12q13, which are expressed during hair growth.

This study found that excessive heat caused the most significant structural changes in hair from Caucasian and Afro samples, especially when combined with other treatments like bleaching and straightening.

This study reports that a new protocol using Angio PRP improved wound healing in mice by enhancing key healing processes and regulating inflammation, suggesting potential for clinical advancements.

This source describes how androgenic alopecia, or pattern hair loss, affects about 70% of men and is linked to factors like stress, hormonal imbalances, and lifestyle issues, which can also impact psychological well-being and potentially contribute to severe health conditions such as heart disease.

This review highlights various alternative and complementary treatments for androgenic alopecia, noting that while only two FDA-approved options exist, increased awareness among dermatologists of supportive evidence for other therapies may better inform patient education.

This study found that specific human hair keratins are differentially expressed in the hair follicle, suggesting a shared pathway of epithelial differentiation between hair cortex and nail plate cells.

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 discusses current topical treatments, natural products, and complementary therapies for androgenetic alopecia, but it reports no new clinical results.

This study found distinct differences in protein expression and wound healing pathways between Acomys cahirinus and Mus musculus, highlighting potential targets for reducing fibrotic response in mammals.

This study found that the Plcd3(mNab) mutation in mice worsens the alopecia caused by Plcd1 loss, suggesting synergistic effects between Plcd1 and Plcd3 on hair follicle health.
