AFM helped show how hair changes under tension and the effects of damage and conditioner.
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 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 Effect of Equilibrium pH on the Structure and Properties of Bleach-Damaged Human Hair Fibers
Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.
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 Development of Predictive Regression Model for Perceived Hair Breakage in Indian Consumers
The model predicts hair breakage based on key hair properties and helps product developers.
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 Fiber-Safe Extraction of Red Mordant Dyes from Hair Fibers
A new method extracts red dyes from wool without damaging it, although it slightly weakens the wool.
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 Improving The Mechanical Properties Of Damaged Hair Using Low-Molecular Weight Hyaluronate
Low-molecular weight hyaluronate can make damaged hair stronger.

Hydrogel scaffolds can help wounds heal better and grow hair.
research Human Hair Follicle-Derived Mesenchymal Stem Cells Promote Tendon Repair in a Rabbit Achilles Tendinopathy Model
Human hair follicle stem cells help repair tendon injuries.
research Hair Resistance to Mechanical Wear
Hair's resistance to wear varies by ethnicity and treatment, with less wear indicating stronger hair.
research Mapping Penetration of Cosmetic Compounds into Hair Fibers Using Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS)
Different oils penetrate hair differently; monounsaturated oils like olive oil penetrate better than polyunsaturated oils.
research Changing the Shape of Hair with Keratin Peptides
Keratin peptides can change hair shape gently without harsh chemicals.
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 Distribution of Glycolipid and Unsaturated Fatty Acids in Human Hair
Human hair has more unsaturated fats inside than on the surface, and certain lipids may help bind the outer and inner layers together.
research Insights on the Mechanical Behavior of Keratin Fibrils
Keratin's mechanical properties are influenced by hydrogen bonds and secondary structure, and can be improved with the SPD-2 peptide.
research Protease Activity, Localization, and Inhibition in the Human Hair Follicle
The study suggests that a new protease inhibitor can make hair harder to pull out, potentially reducing hair loss.
research External Lipid Function in Ethnic Hairs
African hair has the most lipids, while Caucasian hair is more hydrated and stronger.
