330-360 / 1000+ resultsresearch Analysis of heterogeneous reaction between reducing agents and keratin fibers using Raman spectroscopy and microspectrophotometry
The study found that thioglycolic acid breaks down hair bonds more consistently than l-cysteine, which is less damaging to hair.
research Photoinduced formation of thiols in human hair
UV exposure damages hair, increasing thiols and altering protein structure.
research Effects of ultra violet radiation on the soluble proteins of human hair
UV radiation increases protein loss from hair and reduces hair protein quality.
research Copper and calcium uptake in colored hair
Hair coloring increases copper and calcium uptake, damaging hair and reducing shine.
research Raman spectroscopic analysis of L‐phenylalanine and hydrolyzed eggwhite protein penetration into keratin fibers
L-phenylalanine and hydrolyzed eggwhite protein deeply penetrate human hair.
research The Oxidative Degradation of Keratin (Wool and Bovine Hair)
Oxidizing agents break down keratin in wool and hair, causing swelling and increased solubility.
research Modification of wheat gluten for improvement of binding capacity with keratin in hair
Modified wheat protein in shampoo repairs and smooths damaged hair effectively.
research Structure of intermediate filament assembly in hair deduced from hydration studies using small-angle neutron scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
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 Cleave but not leave: Astrotactin proteins in development and disease
Astrotactin proteins are important for brain and skin development and are linked to several neurodevelopmental disorders.
research Evaluation of Cysteic Acid in Bleached Hair Using Infrared Spectroscopy
Bleaching hair increases cysteic acid levels in a predictable way.
research Photo‐protective effect of cuttlefish ink melanin on human hair
Cuttlefish ink melanin protects hair from UV damage.
research Morphological analyses in fragility of pili torti with Björnstad syndrome
Pili torti hair is fragile due to loose keratin filaments and weak disulfide bonds.
research Internal structure changes in bleached black human hair resulting from chemical treatments: A Raman spectroscopic investigation
Chemical treatments on bleached black hair change its internal structure by breaking and reforming bonds, and treatments with hydrolyzed eggwhite protein help repair it.
research Vibrational Raman and IR data on brown hair subjected to bleaching
Bleaching hair changes its structure and weakens it, which is important for understanding hair damage and creating treatments.
research Structural Changes of Hair Keratin by Reduction, Heat and subsequent Oxidation Treatments
DTDG in hair treatments reduces damage and preserves hair 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 Study on modification of rabbit hair fibers with L-cysteine
L-cysteine and ultrasound successfully improved rabbit hair fibers for industrial use.
research Reproduction Mechanism of SS Cross-Links in Permed Hair by the Washing after Reduction with Thioglycolic Acid
Washing permed hair after using thioglycolic acid helps reform strong bonds, making hair stronger.
research A New Permanent Straightening Process of Human Hair Using the Water Set
The new hair straightening method keeps hair straight permanently by using specific creams and heat.
research Internal structural changes in age‐related curved hair due to cyclical extension: An IR spectroscopy study
Age-related hair curvature increases due to internal structural changes from grooming.
research The Viscoelastic Properties of Chemically Modified alpha-Keratins in Human Hair
Chemical modifications can alter hair's stability and flexibility, with hydrophobic interactions helping maintain structure in humid conditions.
