research Comparison on Quality Performance of Human Hair Types with Herbal Oils (Grape Seed/Safflower Seed/Rosehip) by Analysis Techniques
Grape seed oil improved hair quality the most, followed by rosehip and safflower seed oils, and reduced damage from shampoo.
research Hair Lipid Structure: Effect of Surfactants
Surfactants in shampoos and conditioners remove some but not all lipids from hair, and more research is needed to understand their full impact.
research Effects of chemical straighteners on the hair shaft and scalp
Chemical hair straighteners can cause scalp and hair damage, but long-term effects are unclear.

Human hair was used to make biodegradable plastic films that could be useful for packaging and disposable products.
research A comparison of dyeing efficacy between hair‐oxidation‐based and hair‐coating‐based shampoos for the treatment of gray hair
Hair-coating shampoos dye better initially, but hair-oxidation shampoos keep color longer and may damage hair more.
research Magnetic coiffure: Engineering of human hair surfaces with polyelectrolyte-stabilised magnetite nanoparticles
Scientists made human hair magnetic by coating it with special nanoparticles.
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.

K18® and Olaplex® both effectively repair bleached hair, improving its strength, smoothness, and overall health.
research Insights on the Hair Keratin Structure Under Different Drying Conditions
Drying hair with a microfiber towel better maintains hair strength and structure than using a cotton towel or blow-drier.
research Effect of surfactant type on the dyeability and color resistance of semi-permanent basic hair dye
Cationic and nonionic surfactants provide better color intensity and resistance for semi-permanent hair dye than anionic surfactants.
research Understanding the Effect on Hair Fibers of Coloring and Bleaching Formulations Using High Pressure Differential Scanning Calorimetry (HPDSC)
Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.
research Hemostatic properties and the role of cell receptor recognition in human hair keratin protein hydrogels
Keratin from human hair shows promise for medical uses like wound healing and tissue engineering.
research Development of hair care formulations containing Spirulina platensis and Ascophyllum nodosum extracts
The conditioner with Spirulina and Ascophyllum extracts made hair shinier and easier to comb.
research A Raman spectroscopic investigation of the mechanism of the reduction in hair with thioglycerol and the accompanying disulphide conformational changes
Thioglycerol treatment at pH 9.0 with ammonia causes less hair damage and better waving than thioglycolic acid.
research The location of the thioglycolic acid molecules in intrafibrillar unordered areas of the human hair keratin structure
Thioglycolic acid mainly affects the unordered areas in hair structure.
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 Mechanism of Hair Curling via Laccase-Assisted Tyrosine Grafting Using BSA as a Model Protein
A gentler, less damaging method for curling hair using tyrosine works well initially but fades after washing.
research Scanning electron microscopy study of hair shaft changes related to hardness of water
Hard water increases magnesium deposits on hair without changing its structure.
