research Effect of Ethnicity and Treatments on In Situ Tensile Response and Morphological Changes of Human Hair Characterized by Atomic Force Microscopy
Different ethnicities and treatments affect human hair strength and structure.
research Effect of Scalp Position on Tensile Properties of Single Hair Fibers
Hair strength is similar across different scalp areas, and not affected by age, gender, or hair thickness.
research Age, Lifestyle, and Self-Perceptions of Hair: Is There an Association with Hair Diameter and Tensile Properties?
Older age and certain lifestyles are linked to thinner, weaker hair, while how you see your hair relates to its thickness.
research The Susceptibility of Disulfide Bonds to Modification in Keratin Fibers Undergoing Tensile Stress
Disulfide bonds in keratin fibers break more easily under stress, especially when wet, affecting fiber strength.
research Protein Disulfide Isomerase-Mediated Grafting of Cysteine-Containing Peptides onto Over-Bleached Hair
PDI helps restore over-bleached hair's strength and structure by attaching special peptides.
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 Understanding Curly Hair Mechanics: Fiber Strength
Curly hair is mechanically different from straight hair and may need new testing methods.
research Keratin-Based Particles for Protection and Restoration of Hair Properties
Keratin-based particles safely improve hair strength, smoothness, and heat protection.
research Physical Characterization of the Hair of Mexican Women
Mexican women's hair is between Asian and Caucasian hair in thickness and shape, with varied strength and some damage.
research How Different Is Human Hair? A Critical Appraisal of 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 Effect of Rinse-Off Hair Conditioner Containing Argan Oil or Camellia Oil on the Recovery of Hair Damaged by Bleaching
Hair conditioners with argan oil or camellia oil improve the strength and color of bleached hair.
research Single Hair Fiber Assessment Techniques to Discriminate Between Mineral Oil and Coconut Oil Effect on Hair Physical Properties
