research Physical Properties of Human Hair. 1. Evaluation of Bending Stress by Measuring the Major and the Minor Axis of Human Hair.
The cuticle significantly contributes to hair stiffness, making up about 60% of the total bending stress.
research Marangoni effect in the water wetting of surfactant coated human hair fibers
The study found that the Marangoni effect causes the uneven wetting of surfactant-coated hair due to the surfactant moving into the water.
research The adsorption behavior of cationic surfactant onto human hair fibers
A certain surfactant sticks to human hair, making it change from water-repelling to water-attracting, which could help in hair conditioning.
research Human pollution exposure correlates with accelerated ultrastructural degradation of hair fibers
Pollution exposure speeds up hair damage.
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.
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.
research Hardwiring Stem Cell Communication through Tissue Structure
The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.
research Analyzing the laser-light reflection from human hair fibers Part1: Light components underlying the goniophotometric curves and fiber cuticle angles
Hair color affects light reflection, with black hair having higher cuticle angles and lighter hair showing less specular reflection.
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 Cortical cell types and intermediate filament arrangements correlate with fiber curvature in Japanese human hair
Hair curvature in Japanese people is linked to specific cell types and filament arrangements in the hair cortex.
research Structural interspecies variability of mammals' hairs
Mammal hairs have different internal structures.
research The Secrets of Beautiful Hair: Why is it Flexible and Elastic?
Beautiful hair is flexible and elastic due to its unique double-layered structure and can be enhanced with succinic acid treatment.
research Quantifying the effects of repeated dyeing: morphological, mechanical, and chemical changes in human hair fibers
Repeated hair dyeing significantly damages hair.
research General theory of skin reinforcement
Skin and its underlying fat layer act together to resist mechanical stress, and reinforcing this composite structure may help more with anti-aging than just strengthening the skin alone.
research Woolly Antics between the Sheaths
Lipase H is important for hair follicle function and shaping hair fibers.
research Going below and beyond the surface: Microneedle structure, materials, drugs, fabrication, and applications for wound healing and tissue regeneration
Microneedles are effective for painless drug delivery and promoting wound healing and tissue regeneration.
research Biology of Human Hair: Know Your Hair to Control It
Understanding hair biology is key to developing better treatments for hair and scalp issues.
research 190 Deficiency of the Human Cysteine Protease Inhibitor Cystatin M/E Causes Hypotrichosis and Dry Skin
Not having enough cystatin M/E protein causes less hair growth and dry skin.
research Mechanisms of impairment in hair and scalp induced by hair dyeing and perming and potential interventions
Hair dyes and perms can damage hair and scalp, but using interventions can reduce harm.
research Investigation of aging effects in human hair using atomic force microscopy
Aging makes hair thinner and rougher, with less clear edges.
research Anatomy and Function of the Skin
The skin is the largest organ, protecting the body, regulating temperature, and producing hormones.
research Exogenous Factors in Hair Disorders
Outside factors like grooming, chemicals, and the environment can damage hair and cause disorders.
research Perspectives and Challenges of Hair Analysis
Hair is a complex organ, and understanding its detailed structure and growth phases is crucial for analyzing substances within it.
research Three-dimensional ultrastructural analysis of human skin with the arrector pili muscle interacting with the hair follicle epithelium
The method effectively analyzes skin tissue changes, especially in the arrector pili muscle and nerve fibers with hair follicles.
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 Double Network Physical Crosslinked Hydrogel for Healing Skin Wounds: New Formulation Based on Polysaccharides and Zn2+
The new hydrogel with zinc and polysaccharides improves wound healing and has antibacterial properties.
research Structural Hierarchy of Trichocyte Keratin Intermediate Filaments
Keratin proteins are crucial for hair growth and structure.
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 The action of a cosmetic hair treatment on follicle function
The hair treatment made hair grow faster and thicker and strengthened the hair roots.
