Research
60-90 / 1000+ resultsresearch Extractable substances from human hair: a discussion about the origin of the holes
Holes in mature hair are likely caused by the removal of substances during hair care.
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 Photodegradation of human hair: a microscopy study
UV radiation significantly damages hair, especially with humidity, making it more vulnerable to further damage.
research Water-Soluble Polymers in Hair Care
Alkaline hair relaxers damage hair, but cationic and non-ionic polymers can help reduce this damage.
research Interaction of polypeptides with hair in different reducing environments
Small KP peptide improves hair without reducing agents, while larger proteins need them for better results.
research Quantifying whole human hair scalp fibres of varying curl: A micro‐computed tomographic study
Human hair varies in structure based on curl type, with high curl hair showing the most differences.
research Cosmeceuticals for Hair and Nails
Hair care products mainly work on the hair's surface and need professional guidance for use.
research Chronological ageing of human hair keratin fibres
Hair ages as the cuticle wears down, especially beyond 1 meter from the root, affecting its strength and shine.
research Three‐dimensional imaging and analysis of the surface of hair fibres using scanning electron microscopy
The new 3D imaging method accurately measures hair surface details quickly.
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 Recognition of the ultrastructure of the hair follicle of Cashmere goats under the transmission electron microscope
Recognizing ultrastructures of cashmere goat hair follicles helps identify and locate follicle layers.
research The effects of micro-grafts in the treatment of androgenetic alopecia
Micro-grafts improved hair growth in patients with hair loss.
research Structure of intermediate filament assembly in hair deduced from hydration studies using small-angle neutron scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
research Facile and Efficient Enzymatic Methods for Harvesting or Removal of Cuticle Cells from Human Hair Shafts
The conclusion is that new methods for isolating hair cuticle cells and removing the cuticle layer are effective and convenient.
research Adhesion Failure of External Hair Cuticles Caused by Prussian Blue: Possible Electrochemical Roles of Sulfur and Cystine
Prussian Blue causes hair cuticles to detach, weakening the hair.
research A highly resistant structure between cuticle and cortex of human hair
A tough membrane between the outer and inner layers of human hair protects it from damage.
research Wool fiber curvature is correlated with abundance of K38 and specific keratin‐associated proteins
Wool fiber curliness is linked to the presence of certain proteins and K38.
research Hard X-ray Microscopic Images of the Human Hair
High-resolution x-ray images showed three main structures in human hair: medulla, cortex, and cuticle.
research Expression of novel keratin associated protein 5 genes in the cuticle layer of human hair follicles
The study found nine new hair protein genes in human hair follicles.
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 Distribution and Localization of Hydrophobic and Ionic Chemical Groups at the Surface of Bleached Human Hair Fibers
Bleaching hair removes its protective top layer and exposes more hydrophilic groups, changing its chemical surface and affecting how it interacts with products.
research Reactive keratin derivatives: A promising strategy for covalent binding to hair
Modified keratin binds better to hair, especially bleached hair.
research Cross‐linked features of mouse pelage hair resistant to detergent extraction
Two mouse mutants have defective hair cuticle cross-linking.
research Abstracts: Reduction‐induced surface modification of human hair
Chemical treatments change hair surface properties, making it more hydrophilic and able to bind conditioners.
research Discovery of a sol–gel reinforcing the strength of hair structure: mechanisms of action and macroscopic effects on the hair
A small molecule can strengthen fine hair, making it more resistant and natural-feeling.
research Exploring a biological tissue from atomic to macroscopic scale using synchrotron radiation: example of hair.
Hair has unevenly distributed proteins and lipids, with lipids mainly in the cuticle and proteins in the cortex and medulla.
research Photochemical alterations in human hair. I. Artificial irradiation and investigations of hair proteins
Melanin in black hair protects it from sun damage better than light-brown hair.
research Structural changes of hair shaft after application of chemical hair straighteners: Clinical and histopathological study
Chemical hair straightening improves smoothness and shine but may cause side effects, suggesting a need for safer methods.
