Research cited in this study
24 / 24 results
research The Proteomic Profile of Hair Damage
This study discusses the proteomic profile associated with hair damage but does not report new experimental findings.
research Copper and Calcium Uptake in Colored Hair
This study used nanoscale secondary ion mass spectrometry to locate where calcium and copper are concentrated in colored hair, finding these metals particularly in the cuticle's sulfur-rich regions.
research The Keratins of the Human Beard Hair Medulla: The Riddle in the Middle
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.
research The Occurrence and Incorporation of Copper and Zinc in Hair and Their Potential Role as Bioindicators: A Review
This review explores how copper and zinc concentrations in hair may serve as bioindicators and discusses their potential associations with health disorders, but it reports no new clinical findings.
research Characterization of the Exocuticle A-Layer Proteins of Wool
This study found that the outer protein layer of Merino wool is rich in sulfur-containing proteins similar to those found in both sheep wool and human hair.
research Human Hair Keratin-Associated Proteins
Keratin-associated proteins are crucial for hair strength and structure.
research Characterization of the Lipid Composition at the Proximal Root Regions of Human Hair
This study observed that in Japanese females, hair lipid composition showed significant correlations, suggesting CH and CERs may act as a barrier against sebum-derived lipids.
research Free Internal Lipids in Hair From Pre- and Post-Menopausal Women
This study found that menopause alters hair lipids and reduces hair quality, with hormone replacement therapy mitigating some changes.
research Keratins of the Human Hair Follicle
More research is needed to understand how hair keratins work and their role in hair disorders.
research Hair Follicle Differentiation And Regulation
This review discusses advances in understanding hair and hair follicle structure, gene expression, and molecular signals in hair formation, without reporting new clinical findings.
research Hair Keratin Associated Proteins: Characterization of a Second High Sulfur KAP Gene Domain on Human Chromosome 21 in Fond Memory of Dr. Peter Steinert
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.
research Chemical and Photo-Oxidative Hair Damage Studied by Dye Diffusion and Electrophoresis
This study found that chemical and photochemical oxidative processes modify the main classes of proteins in hair, confirmed through microspectrophotometric, fluorescence microscopy, and electrophoretic methods.
research The Catalog of Human Hair Keratins
This study cataloged human type II hair keratins, detailing their expression and differentiation roles in hair follicles and comparing them with type I keratins to explore keratin-pairing principles.
research The Catalog of Human Hair Keratins
This study establishes a catalog of human type I hair keratins and identifies their specific roles and expression patterns during hair differentiation and growth in scalp follicles.
research The Role of Keratin Proteins and Their Genes in the Growth, Structure, and Properties of Hair
This article integrates existing literature on hair follicle structure and formation at the cellular and molecular level, reporting no new findings.
research Sebum Flow Dynamics and Antidandruff Shampoos
This study found that among 120 men, two antidandruff shampoos increased sebum excretion rate, while one shampoo decreased sebum output, highlighting distinct effects on the follicular reservoir.
research Formation and Structure of Human Hair
This review examines the histochemistry and keratinization processes of human hair, exploring the structural roles of keratin proteins, protein chains, and lipids, but offers no new results.
research Differential Expression of Genes Encoding a Cysteine-Rich Keratin Family in the Hair Cuticle
research Ultrastructural Visualization of Cross-Linked Protein Features in Epidermal Appendages
This study found that the extraction-resistant structures in hair, feathers, and hagfish teeth are due to ε-(γ-glutamyl)lysine cross-linked proteins, emphasizing their role in maintaining the integrity of these materials.
research Special Biochemical Features of the Hair Follicle
Hair follicles have unique proteins that vary by species and are influenced by nutrition.
research Specific Keratins And Their Associated Proteins As Markers For Hair Follicle Differentiation
research Degradation Of Human Hair By Papain
This study found that papain/bisulfite disintegrates human hair cuticles by dissolving the endocuticle, potentially accelerated by ethanol's removal of cell membrane material.
research Electron Microscope Studies of Hair and Wool
This article reports electron microscope studies on the structure of hair and wool, but it does not present new clinical findings.
research The N- And C-Terminal End Groups Of Hair Keratin
This study identified the same N-terminal and C-terminal amino acids in human and horse hair as previously found in wool and feather keratin.
