research Effect of equilibrium pH on the structure and properties of bleach‐damaged human hair fibers
Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.
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 Secondary ion mass spectrometric investigation of penetration of coconut and mineral oils into human hair fibers: relevance to hair damage.
Coconut oil can penetrate hair better than mineral oil, potentially protecting against damage.
research An ultrastuctural study of hair fiber damage and restoration following treatment with permanent hair dye
Permanent hair dye damages hair but it mostly recovers after 8 weeks; using certain hair care products can help repair it.
research Evaluation of Various Therapies for Damaged Scalps Due to Hair and Fiber Implants
Synthetic fiber hair implants often cause complications and are not very successful.
research Repair of damaged hair protein fiber by jointly using transglutaminase and keratin
Using an enzyme and keratin treatment can significantly repair and strengthen damaged hair.
research A Morphological Study of Restoration of Damaged Hair Fiber With Chemical Treatments Using Microscopy Techniques
The high-cost product with coconut oil and glycerol effectively restores severely damaged hair.
research Comparison of damage to human hair fibers caused by monoethanolamine- and ammonia-based hair colorants.
Monoethanolamine-based hair colorants can cause more damage to hair than ammonia-based ones.
research 3P343 Change of cell membrane complex of a hair fiber caused by hair damage
Chemical treatments damage hair more than UV exposure, making it thinner and less flexible.
research Carbonylation of hair proteins: A robust biomarker of molecular and structural oxidative damage in hair fibres
Protein carbonylation is a sensitive marker for oxidative damage in hair, especially from light exposure.
research Protein Carbonylation as a Reliable Read-Out of Urban Pollution Damage/Protection of Hair Fibers
research Exploring the Effects of Wetting and Free Fatty Acid Deposition on an Atomistic Hair Fiber Surface Model Incorporating Keratin-Associated Protein 5-1
Damaged hair allows water to penetrate more easily, and fatty acids from shampoos can deposit on hair surfaces.
research Characterization of the mechanical properties of the cortex region of human hair fibers by multiparametric Atomic Force Microscopy mapping
Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.
research Unveiling the link between surface physicochemistry and nanomechanical behavior in bleached and UV-irradiated human hair fibers
Bleaching and UV exposure significantly damage hair.
research Wetting behavior of human hair fibers
Human hair's ability to get wet is complex and can change with treatments, damage, and environment.
research Cuticle damage and the tensile properties of human hair
Cuticle damage doesn't affect hair's tensile strength; the cortex is responsible for it.
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 Enzymatic Method for Assessing Hair Damage with Reduction and Subsequent Oxidation
Permed hair degrades faster and shows more damage after protease treatment compared to untreated hair.
research Structural investigation on damaged hair keratin treated with α,β-unsaturated Michael acceptors used as repairing agents
Treatments improved hair surface and scale structure but didn't increase certain bonds in the hair cortex.
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 Tensile properties of twisted hair fibers
Twisting hair weakens it, but strength can be recovered at low twist levels.
research A reciprocal lattice approach to assessing the luster of hair fibers, based on scattering by periodically deformed cylinders
A new method helps understand hair shine and various products improve hair care.
research Photoageing of Hair Fiber and Photoprotection
Sunlight damages hair, causing cuticle loss, protein changes, and discoloration.
research Thermal Damage, Styling Product Overuse, and Heat Protection Strategies in Professional Hairstyling: An Expert-Based Protocol for Hair Structure Preservation
Use heat protection and proper techniques to prevent hair damage from styling.
research Thermal Damage, Styling Product Overuse, and Heat Protection Strategies in Professional Hairstyling: An Expert-Based Protocol for Hair Structure Preservation
Use heat protection and proper techniques to prevent hair damage from styling.
research Quasi-Static Torsional Deformation of Single Hair Fibers: Application of a Modeling Approach and Results from Cosmetic Treatments.
The research found that twisting hair fibers can show changes in stiffness and damage, and help tell apart different hair treatments.
research Failure of intercellular adhesion in hair fibers with regard to hair condition and strain conditions
Hair breaks differently when wet or dry and is affected by its condition and treatments like perms and bleaching.
research Torsional method for evaluating hair damage and performance of hair care ingredients
The torsional method effectively evaluates hair damage and the performance of hair care ingredients.
research Microscopic high-resolution digital volumetric imaging of human hair fibers
DVI provides detailed 3D imaging of hair and shows how various products protect and enhance hair.
