research Penetration of cationic conditioning compounds into hair fibers: A TOF‐SIMS approach
The study found that certain conditioning compounds can penetrate hair and potentially improve its resistance to damage.
research Exploring the effects of wetting and free fatty acid deposition on an atomistic hair fiber surface model incorporating Keratin Associated Protein 5-1
Water and fatty acids affect hair's surface differently based on hair damage, and models can help understand hair-cosmetic interactions.
research Mechanical properties characterization of human hair fibers cortex region by multiparametric Atomic Force Microscopy mapping
The active ingredient improves the strength of damaged hair fibers.
research Experimental Investigations on Hair Fibers as Diffusion Bridges and Opiates as Solutes in Solution
Hair can absorb and transfer opiates when soaked in water, with damaged hair absorbing more.
research Human pollution exposure correlates with accelerated ultrastructural degradation of hair fibers
Pollution exposure speeds up hair damage.
research Analysis of Cysteine on the Surface of Hair Fibers with Spectrofluorescence
Cysteine formation on hair indicates damage, best detected at pH 4.5.
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 Enzyme Treatment of Wool and Specialty Hair Fibers
Enzymes xylanase and pectinase clean wool and specialty hair fibers effectively without damage, offering an eco-friendly alternative to soap and hot water.
research Non-denatured Soybean Extracts in Skin Care: Multiple Anti-Aging Effects
Non-denatured soybean extracts provide multiple anti-aging skin benefits.
research 13. Wound Healing
Fine hairs improve male pattern baldness treatment, alopecia areata causes remain unknown, and hair can recover from dye damage over time.
research Water-Soluble Polymers in Hair Care
Alkaline hair relaxers damage hair, but cationic and non-ionic polymers can help reduce this damage.
research Changes in intraepidermal nerve fiber and Langerhans cell densities in the plantar skin of rats after mercuric chloride exposure
Mercury exposure damages small nerve fibers in rats' skin.
research Alopecia: histologic changes.
The review found that specific changes in scalp tissue can help diagnose different types of hair loss.
research The Gut-Brain-Skin Axis and Role of Intestinal Dysbiosis in Acne Vulgaris: Therapeutic Effects of Pro- and Prebiotic Use
Probiotics and dietary changes can help treat acne.
research Effects of high-power millimeter wave on mice skin at different time points of radiation
Longer exposure to high-power millimeter wave radiation causes more severe skin damage in mice.
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 Photodegradation of human hair: a microscopy study
UV radiation significantly damages hair, especially with humidity, making it more vulnerable to further damage.
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 Scanning Electron Microscope Evaluation of Hair Dye Effects on the Cuticle Cells of Canine Hair
Hair dye can damage dog hair and cause health issues.
research Age-Related Variations in the Population of Active Secondary Hair Follicles, Oxidative Stress and Antioxidant Parameters in Cashmere Goats
Younger cashmere goats produce more and better-quality fiber due to higher active hair follicles and antioxidant capacity.
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 Chemical modification of keratin fibers using 2‐iminothiorane hydrochloride
2-iminothiorane hydrochloride improves hair waving permanence without damage.
research Photodegradation of hair of different ethnicity after 1 year of exposure to natural weathering in Arizona
Hair with more melanin resists weather damage better.
research Nanomechanical characterization of human hair using nanoindentation and SEM
Human hair's strength and flexibility vary by ethnicity, damage, and treatment.
research Dyeing Behavior of Yak Hair Fiber Treated with Microwave Low Temperature Plasma
Microwave plasma treatment improves yak hair dyeing.
research Promotion effect of Schisandra nigra on the growth of hair

research Chemical and photo-oxidative hair damage studied by dye diffusion and electrophoresis.
Chemical treatments and light exposure damage hair proteins.
research Evaluation of hair fibers properties treated with acid straightener at different pH values
Hair straightening at pH 1.0 improves alignment but weakens hair more than pH 2.0.
research Stability of opiates in hair fibers after exposure to cosmetic treatment
Cosmetic treatments like bleaching and perming can greatly reduce opiate levels in hair, possibly leading to false-negative drug tests.
