research Exogenous and endogenous lipids of human hair
Removing external lipids from hair reduces moisture and increases strength, while removing internal lipids decreases water permeability.
research Hair cuticle differences between Asian and Caucasian females
Asian hair is stronger and more damage-resistant than Caucasian hair due to a thicker cuticle layer.
research The proteomic profile of hair damage
Bleaching hair damages protein structure, especially keratin, leading to weakened hair.
research Photoageing of Hair Fiber and Photoprotection
Sunlight damages hair, causing cuticle loss, protein changes, and discoloration.
research Seasonal changes in the morphology of wool follicles in Finewool and Strongwool Merino strains grazing at different stocking rates in southern Australia
Stocking rate affects wool follicle inactivity, not Merino strain.
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 Fiber-Safe Extraction of Red Mordant Dyes from Hair Fibers
Researchers developed a less damaging way to extract red dyes from wool using EDTA and DMF, preserving the fiber's strength for further analysis.
research New keratin isolates: actives for natural hair protection.
Keratin helps protect and strengthen hair, reducing damage and color fading.
research An Innovative Experimental Petrographic Study of Concrete Produced by Animal Bones and Human Hair Fibers
Concrete made from animal bones and human hair is stronger and more environmentally friendly than traditional concrete.
research Systems Approach to Human Hair Fibers: Interdependence Between Physical, Mechanical, Biochemical and Geometric Properties of Natural Healthy Hair
Hair properties are interconnected; a comprehensive, cross-disciplinary approach is essential for understanding hair behavior.
research A Clinical Trial to Investigate the Effect of Cynatine HNS on Hair and Nail Parameters
Cynatine HNS improves hair and nail quality in 90 days.
research Ceramide: A New Approach to Hair Protection and Conditioning.
Ceramide treatment can strengthen and protect hair from damage.
research Comparative evaluation between two nutritional supplements in the improvement of telogen effluvium
One supplement improved hair loss and quality faster and more effectively than the other in treating telogen effluvium.
research Effect of Waste Human Hair Fibers on Shear Behavior of Sand in Dry and Saturated Conditions
Adding human hair to sand improves its strength when dry and maintains strength when wet.
research How different is human hair? A critical appraisal of the reported differences in global hair fibre characteristics and properties towards defining a more relevant framework for hair type classification
Human hair varies widely and should be classified by curl type rather than race.
research Efficacy and safety of a new formulation kit (shampoo + lotion) containing anti‐inflammatory and antioxidant agents to treat hair loss
The new hair loss treatment kit was safe and improved hair growth without any adverse effects.
research Protective effect of conditioner agents on hair treated with oxidative hair dye
Conditioners in hair dye reduce damage and improve combability.
research Photo‐protective effect of cuttlefish ink melanin on human hair
Cuttlefish ink melanin protects hair from UV damage.
research Penetration of different molecular weight hydrolysed keratins into hair fibres and their effects on the physical properties of textured hair
Different sizes of keratin peptides can strengthen hair, with smaller ones possibly increasing volume and larger ones repairing damage.
research Hair Growth Promoting Effect of 4HGF Encapsulated with PGA Nanoparticles (PGA-4HGF) by β-Catenin Activation and Its Related Cell Cycle Molecules
PGA-4HGF may help treat hair loss by activating hair growth pathways and extending the hair growth phase.
research Wear characteristics of epoxy based hybrid composites reinforced with short hair fibers and glass micro spheres
Adding human hair fibers and glass micro-spheres to epoxy improves its wear resistance and strength.
research Molecular elements of the regulatory control of keratin filament modulator AHF/trichohyalin in the hair follicle
The study concluded that a protein important for hair strength is regulated by certain molecular processes and is affected by growth phases.
research The role of androgens in hormone replacement therapy
Androgen therapy can help with symptoms like low libido in women, but more research is needed to understand its long-term safety and effects on health.
research Immune Cells in Cutaneous Wound Healing: A Review of Functional Data from Animal Models
Different immune cells like platelets, mast cells, neutrophils, macrophages, T cells, B cells, and innate lymphoid cells all play roles in skin wound healing, but more research is needed due to inconsistent results and the complex nature of the immune response.
research Hair and amino acids: the interactions and the effects.
Amino acids in conditioners improve hair strength, hydration, and color retention.
research The failure behavior of the anchorage of hairs during slow extraction
Growing hairs are easier to pull out than resting hairs due to different anchorage strengths.
research Structural Color of Partially Deacetylated Chitin Nanowhisker Film Inspired by Jewel Beetle
The film creates vibrant colors and can be used in food sensors and cosmetics.
research Optical coherence tomography to evaluate the effects of oxidative hair dye on the fiber
Oxidative hair dye changes hair color and structure but doesn't weaken it.
research Single hair fiber assessment techniques to discriminate between mineral oil and coconut oil effect on hair physical properties
Coconut oil makes hair stronger and more flexible than mineral oil.
