research Evaluation method of the degree of hair damage. (I). Measurement of tensile strength of human hair by "the multi-point tension test method".
The method accurately measures hair damage and strength, revealing effects of cosmetics and metal correlations.
research Application of single hair fibre tensile measurements to create an industry‐standard heat damage scale for hair
A new 6-point scale reliably measures heat damage to hair from styling tools.
research Evaluation of sensory parameters and tensile strength on damaged hair after ten washes with Mintop shampoo: in vitro study
Mintop shampoo improved hair smoothness, shine, and strength after ten washes.
research Impact of Personal Care Products on Tensile Strength and Structure of Hair
More research is needed to understand how shampoo chemicals affect hair strength and structure.
research An ex vivo comparative study of the tensile strengthening efficacy of protein-derived actives on heavily bleached hair
Protein-derived ingredients can help strengthen bleached hair.
research In-Situ Tensile Testing of Hair Fibers in An Environmental Scanning Electron Microscope (ESEM)
Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.
research Sustainable Biopolymer Based on Tung Oil and Tung Free Fatty Acids for Hair Tensile Enhancement
The TO-TF copolymer strengthens damaged hair effectively and sustainably.
research Effects of Hair Follicle Stem Cells on Partial-Thickness Burn Wound Healing and Tensile Strength
Hair follicle stem cells improve burn wound healing and strength in rats.
research A Study of Aggregation Structures and Tensile Properties of Hair Fibers
research Effect of oral intake of choline-stabilized orthosilicic acid on hair tensile strength and morphology in women with fine hair
research Analysis of structural changes in permanent waved human hair using Raman spectroscopy
Permanent waving weakens hair by altering its protein structure.
research The interaction between surfactants and keratinous tissues
Surfactants can protect or harm hair, skin, and nails, depending on their type and use.
research Characteristic features of ageing in Korean women’s hair and scalp
Korean women's hair thins, weakens, and greys with age, with mineral and sterol changes.
research Significant damage of the skin and hair following hair bleaching
Hair bleaching causes significant damage to hair and skin.
research Regulation of hard α-keratin mechanics via control of intermediate filament hydration: matrix squeeze revisited
Hard α-keratins stay stiff in water because the surrounding matrix keeps them dehydrated and strong.
research Protein disulphide 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 Transgenic mice overexpressing CD109 in the epidermis display decreased inflammation and granulation tissue and improved collagen architecture during wound healing
Mice genetically modified to produce more CD109 in their skin had less inflammation and better healing with less scarring.
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 Quantifying hair shape and hair damage induced during reshaping of hair.
New imaging and testing methods can effectively assess hair shape changes and damage.
research Secondary structure estimation and properties analysis of stretched Asian and Caucasian hair
Stretching damages Caucasian hair's structure more easily than Asian hair.
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 and amino acids: the interactions and the effects.
Amino acids in conditioners improve hair strength, hydration, and color retention.
research High-Performance Wigs via the Langmuir–Blodgett Deposition of Keratin/Graphene Oxide Nanocomposite
New wig coating technique makes them more durable, UV resistant, and less static.
research Visible Light-Mediated Environmentally Friendly and Universally Applicable Green Chemistry for Hair Cross-Linking

research Effects of permanent waving on changes of protein and physicomorphological properties in human head hair.
Repeated digital perming with sodium thioglycolate lotion significantly damages hair protein and structure.
research Water-Soluble Polymers in Hair Care
Alkaline hair relaxers damage hair, but cationic and non-ionic polymers can help reduce this damage.
research Investigating the relationship between the hair fiber proteome and hair quality
Hair quality is genetically determined and linked to its composition and strength.
