16 / 16 results research Analysis of Heterogeneous Reaction Between Reducing Agents and Keratin Fibers Using Raman Spectroscopy and Microspectrophotometry
The study found that thioglycolic acid breaks down hair bonds more consistently than l-cysteine, which is less damaging to hair.
research Diffusion Behavior of Poly(Ethylene Imine) Into Keratin Fibers Using Microspectrophotometry
PEI diffuses into hair at a constant rate, and urea speeds up this process.
research Photodegradation of Human Hair: A Microscopy Study
UV radiation significantly damages hair, especially with humidity, making it more vulnerable to further damage.
research Chemical and Photo-Oxidative Hair Damage Studied by Dye Diffusion and Electrophoresis
Chemical treatments and light exposure damage hair proteins.
research Photodegradation of Hair of Different Ethnicities After One Year of Exposure to Natural Weathering in Arizona
Hair with more melanin resists weather damage better.
research Action of Thioglycolic Acid and L-Cysteine on Disulfide Cross-Links in Hair Fibers During Permanent Waving Treatment
Thioglycolic acid and L-cysteine change hair structure differently during perms, affecting hair strength and curling efficiency.
research RGB Video Microscopic System for In Vitro Monitoring of Optical Properties of Hair Shaft and Follicle
The system helps monitor hair properties using RGB video microscopy.
research Analysis of Structural Changes in Permanent Waved Human Hair Using Raman Spectroscopy
Permanent waving weakens hair by altering its protein structure.
research Investigating the Relationship Between the Hair Fiber Proteome and Hair Quality
Hair quality is genetically determined and linked to its composition and strength.
research Intermolecular Disulfide Cross-Linked Structural Change Induced by Permanent Wave Treatment of Human Hair with Thioglycolic Acid
Permanent wave treatment with thioglycolic acid changes hair structure by altering disulfide bonds.
research In Vitro and In Vivo Study of Dye Diffusion into Human Skin and Hair Follicles
Dyes can penetrate human skin and hair follicles up to 1.2 mm deep and the sebaceous gland can store dye; Indocyanine Green lotion was made for safe dyeing and monitoring.
research Strategies for Improved Hair Binding: Keratin Fractions and the Impact of Cationic Substructures
Certain treatments can increase protein binding to natural hair but are less effective on permed hair.
research Commensal Microbiome Promotes Hair Follicle Regeneration by Inducing Keratinocyte HIF-1α Signaling and Glutamine Metabolism
The skin's microbiome helps hair regrow by boosting certain cell signals and metabolism.
research The Anti-Flyaway/Frizz Effect by Inducing the Alpha-Helical Structure Transition of Hair
ATG effectively reduces hair frizz without damaging hair strength.
research Interactions Between Damaged Hair Keratin and Juglone as a Possible Restoring Agent: A Vibrational and Scanning Electron Microscopy Study
