research Possible relationships between the physical conditions of cattle and the occurrence of structural modifications of their coat hair
Vitamin A deficiency changes cattle hair structure, while pregnancy may improve it, suggesting hair can indicate cattle health.
research Understanding the Effect on Hair Fibers of Coloring and Bleaching Formulations Using High Pressure Differential Scanning Calorimetry (HPDSC)
Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.
research Disulfide Cross-Linked Network Structure of Intermediate Filament and Matrix in Hair and Wool Cortices
Hair and wool strength is affected by the number and type of bonds in their protein structures, with hair having more protein aggregates than wool.
research Properties of Partially Extracted Hairs and their Degradability by Proteases
Mf-rich hair degrades more than Ma-rich hair, especially with Proteinase K.
research Structure and hair follicle-specific expression of genes encoding the rat high sulfur protein B2 family
The B2 genes are crucial for hair growth in rats.
research Penetration of different molecular weight hydrolysed keratins into hair fibres and their effects on the physical properties of textured hair
Different sizes of keratin peptides can strengthen hair, with smaller ones possibly increasing volume and larger ones repairing damage.
research Impact of Hair Damage on the Penetration Profile of Coconut, Avocado, and Argan Oils into Caucasian Hair Fibers
Different oils affect hair flexibility and strength, with their impact varying on whether hair is virgin or bleached.
research Chapter 4 Cytomechanics of Hair
Hair's strength and flexibility come from its protein structure and molecular interactions.
research Biomechanics of hair fibre growth: A multi-scale modeling approach
The model shows that factors like follicle shape and stiffness are key for hair growth and anchoring.
research Fine structure and immunocytochemistry of monotreme hairs, with emphasis on the inner root sheath and trichohyalin‐based cornification during hair evolution
Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.
research Structure and Mechanical Properties of Human Trichocyte Keratin Intermediate Filament Protein
Disulfide bonds make keratin in hair stronger and tougher.
research Dose-Dependent Histopathological and Structural Impact of Chemical Hair-Straighteners on Scalp Epithelium and Hair-Fibres Using Albino Wistar Rats
Chemical hair straighteners can severely damage hair and scalp with repeated use.
research Science and Technology of Hair Fibers
The document concludes that understanding hair's composition and the effects of treatments can lead to better hair care products.
research Protein disulphide isomerase-mediated grafting of cysteine-containing peptides onto over-bleached hair
PDI helps restore over-bleached hair's strength and structure by attaching special peptides.
research Hyaluronic acid: elucidating its penetration into, and effect on hair fibers using confocal Raman spectroscopy and biometric techniques
Hyaluronic acid in shampoo penetrated hair well, reduced frizz, and improved hair strength and moisture.
research The Catalog of Human Hair Keratins
Human hair keratins were cataloged, showing their roles in hair differentiation stages.
research Heat‐damaged evaluation of virgin hair
Heat damages hair, with Asian hair losing more protein than Caucasian hair.
research Qualitative investigation of fresh human scalp hair with full-field optical coherence tomography
Melanin density affects hair color, and this method can help in cosmetic assessments and diagnosing hair diseases.
research Bubble Hair and the Usefulness of Trichoscopy
Bubble hair damage is caused by high heat from styling tools, and trichoscopy helps diagnose it.
research Identification of the Keratin-Associated Protein 22-2 Gene in the Capra hircus and Association of Its Variation with Cashmere Traits
A new goat gene affects cashmere fiber thickness; certain variations can make the fibers coarser.
research Thermal Induced Changes in Cuticle and Cortex to Chemically Treated Hair
Heat worsens damage in chemically treated hair, especially bleached and straightened hair.
research Ziehl-Neelsen's stain for skin sections to show wool and hair follicles
Ziehl-Neelsen's stain helps identify different parts of hair in sheep and goats.
research Keratins: the hair shaft's backbone revealed
Keratins are crucial for hair strength, and mutations in certain keratin genes cause hair disorders.
research Lipid loses and barrier function modifications of the brown‐to‐white hair transition
White hair has less lipid content and absorbs water differently than brown hair.
research Histological Study for Skin of Horse
Horse skin has a layered epidermis, a dermis with hair follicles, sweat and sebaceous glands, and is supplied by small arteries.
research On Pathways for Small Molecules Into and Out of Human Hair Fibers
Dye enters hair at the edges of cuticle cells and penetrates more from water than alcohol-based solutions.
research Local structure of human hair spatially resolved by sub-micron X-ray beam
Human hair has a new region with ordered filaments and the cuticle contains β-keratin sheets.
research Investigation of aging effects in human hair using atomic force microscopy
Aging makes hair thinner and rougher, with less clear edges.
research Perspectives on Hair Evolution Based on Some Comparative Studies on Vertebrate Cornification
Hair in mammals likely evolved from glandular structures, not scales.
