Chemical treatments and daily stresses damage hair, especially the cuticle layer.
research Effect of Surface Treatments on the Nanomechanical Properties of Human Hair
Bleaching and combing damage hair's surface and mechanical properties.
research Chemical and physical treatments damage Caucasian and Afro‐ethnic hair fibre: analytical and image assays
Chemical and physical treatments like bleaching, dyeing, and UV radiation damage both Caucasian and Afro-ethnic hair.
research Hair removal
Current hair removal methods improve appearance but need more research for better options.
research Investigations on the penetration of hydrolyzed wheat proteins into human hair by confocal laser-scanning fluorescence microscopy
Hydrolyzed wheat proteins penetrate all hair types effectively.
research A systematic review on the lipid composition of human hair
Lipids are crucial for healthy hair, protecting it from damage and breakage.
research Preparation of Water Soluble Wool Keratin and Its Application for Human Hair
Water-soluble wool keratin can protect human hair from damage during treatments.
research Effects of silicone pretreatment on oxidative hair damage

Keratin film can effectively mimic human hair for testing hair damage.
research Non‐invasive evaluation of hair interior morphology by X‐ray microscope
X-ray microscopy can non-invasively show hair structure changes after treatments, but it's less detailed than TEM and needs improvement.
research Hair Lipid Structure: Effect of Surfactants
Surfactants in shampoos and conditioners remove some but not all lipids from hair, and more research is needed to understand their full impact.
research J. Cosmet. Sci., 58, 629–636 (November/December 2007) Hair breakage during combing. IV. Brushing and combing hair
Brushing causes more long hair breaks than combing, especially with bleached or wet hair.
research In search of hair damage using metabolomics?
Metabolomics can identify hair damage markers, but its use in creating treatments is uncertain.
research The chlorine-hair interaction. III. Effect of combining chlorination with cosmetic treatments on hair properties
Cosmetic treatments after chlorination damage hair more than treatments before.
research Thermoporometry measurements of human hair via differential scanning calorimetry
Bleaching hair increases pore size and changes pore structure.
research Unveiling the link between surface physicochemistry and nanomechanical behavior in bleached and UV-irradiated human hair fibers
Bleaching and UV exposure significantly damage hair.
research Thermal Induced Changes in Cuticle and Cortex to Chemically Treated Hair
Heat worsens damage in chemically treated hair, especially bleached and straightened hair.
research Utilizing Lipid Bond Technology With Molecular Lipid Complex to Provide Lipid Treatment for Damaged Hair
The treatment effectively repairs and strengthens damaged hair by restoring natural lipids.
research Chemical bonds and hair behaviour—A review
Disulfide bonds are crucial for hair's strength, especially when wet.
research A methodological exploration of distinguishing hair quality based on hair proteomics
Bleaching damages hair by reducing the quality of keratin and keratin-associated proteins.
research Characterization of the mechanical properties of the cortex region of human hair fibers by multiparametric Atomic Force Microscopy mapping
Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.
research Investigation of the Changes in the Hair Cuticle Due to Chemical Degradation
Chemical treatments severely damage hair cuticles, especially in previously treated hair.
