research Age-associated thin hair displays molecular, structural and mechanical characteristic changes
Older thin hair is not just thinner but also has different shape, structure, and stiffness.
research Solubility of Structurally Complicated Materials: 3. Hair
Hair is hard to dissolve because of its complex proteins, but certain solvents that break specific bonds and hydrate can do it.
research New Aspects of the Structure of Human Scalp Hair-II: Tubular Structure and Material Flow Property of the Medulla.
The medulla in Asian scalp hair has a tubular structure that allows ions and large molecules to flow through it.
research INTERACTION OF ZN(II) WITH BOVINE MILK α-CASEIN: STRUCTURE-FUNCTION STUDY
Zinc binds to milk protein α-casein, forming stable complexes that could help fortify milk with zinc to prevent deficiencies.
research Effects of repeated exposure to ozonated water on hair fibre structure and integrity: Part I
This study examined the effects of repeated exposure to ozonated water on hair fibre structure and integrity. The results showed that ozonated water caused oxidative modifications in hair proteins, lipids, and pigments, leading to changes in structural, chemical, and functional properties. Specifically, there were increases in cysteic acid-related bands and carbonyl groups, indicating protein and lipid oxidation. Morphological changes included cuticle fusion and increased cortical fluorescence. Mechanical properties were affected, with increased denaturation temperature and post-yield stiffness, suggesting altered crosslink density and keratin disruption. Despite these changes, alterations in shine and colour were minimal. The study concludes that ozone exposure results in a unique damage signature affecting both the cuticle and cortex, warranting further investigation into lipidomic and biochemical changes and the hair's response to additional stressors.

research Effect of disulfide bonds in human hair fibers on the melting behavior of their crystalline structure
Disulfide bonds affect the melting behavior of hair's crystalline structure, but hair retains some stability even after these bonds are broken.
research Convergent Evolution of Cysteine-Rich Keratins in Hard Skin Appendages of Terrestrial Vertebrates
Cysteine-rich keratins evolved independently in mammals, reptiles, and birds for hard skin structures like hair, claws, and feathers.
research Ageing processes influence keratin and KAP expression in human hair follicles
