90-120 / 1000+ results research In Vitro Evaluation of the Effect of a Not Cross-Linked Hyaluronic Acid Hydrogel on Human Keratinocytes for Mesotherapy
HYDRO DELUXE BIO hyaluronic acid hydrogel is compatible with skin cells, may reduce inflammation, promote blood vessel growth, and protect against oxidative stress, suggesting it could help revitalize hair follicles.
research Characterizing Wool Keratin
Wool keratin is reactive, biocompatible, biodegradable, and can model keratin from other sources.
research Laccase-catalyzed poly(tyrosine) grafting improves the performance of wool
Using laccase to add poly(tyrosine) to wool makes it less likely to shrink and stronger.
research Nε-(carboxymethyl) lysine represses hair follicle formation by inhibiting Sonic hedgehog expression in a NF-κB-independent manner
Nε-(carboxymethyl) lysine delays hair growth by blocking a key protein.
research Structural Stability of Wild Type and Mutated α-Keratin Fragments: Molecular Dynamics and Free Energy Calculations
The Glu413Lys mutation in keratin affects hair stability, while Glu413Asp does not.
research Internal structure changes in bleached black human hair resulting from chemical treatments: A Raman spectroscopic investigation
Chemical treatments on bleached black hair change its internal structure by breaking and reforming bonds, and treatments with hydrolyzed eggwhite protein help repair it.
research Characterization of transport systems for cysteine, lysine, alanine, and leucine in wool follicles of sheep
Sheep wool follicles absorb different amino acids at various rates and locations, which could affect wool growth based on diet and genetics.
research Ultrastructural visualization of cross-linked protein features in epidermal appendages
Cross-linked proteins help maintain the structure of hair, feathers, and hagfish teeth.
research A Fatty Acid / Protein Complex in Human Hair
A fatty acid/protein complex in human hair helps protect it from damage.
research Enhanced substantivity of hyaluronic acid on keratin substrates via polymer complexation
Polymer complexation makes hyaluronic acid stick to hair better, enhancing its moisturizing effects.
