research Action of Thioglycolic Acid and L-Cysteine to Disulfide Cross-Links in Hair Fibers during Permanent Waving Treatment
Thioglycolic acid and L-cysteine change hair structure differently during perms, affecting hair strength and curling efficiency.
research Hair Keratins and Hair Follicle–Specific Epithelial Keratins
Hair and follicle keratins differ in structure and expression, especially in cysteine content.
research ELECTRON MICROSCOPE STUDIES OF HAIR AND WOOL
Hair and wool have complex microscopic structures with microfibrils and varying cystine content.
research Enzymatic approach to analyze the effects of mercaptans on hair
Mercaptans make hair more prone to damage, with reduced hair being more affected than permed hair.
research Polarization Microscopy of Hair in Acrodermatitis Enteropathica
Zinc therapy improved hair health in a girl with acrodermatitis enteropathica.
research Characterization of tiger tail banding and hair shaft abnormalities in trichothiodystrophy
Tiger tail banding and hair abnormalities are reliable indicators for diagnosing trichothiodystrophy.
research In utero Diagnosis of Trichothiodystrophy by Endoscopically-Guided Fetal Eyebrow Biopsy
Prenatal diagnosis of trichothiodystrophy is possible in the second trimester using fetal eyebrow biopsy, with sulfur content analysis being more reliable.
research Molecular evolution of the keratin associated protein gene family in mammals, role in the evolution of mammalian hair
KRTAP genes evolved early in mammals, leading to diverse hair traits.
research DSC-investigations of alpha-keratins and the specific effects of chemical treatments on human hair
Chemical treatments weaken hair's thermal stability and structure.
research Diagnosis of Trichothiodystrophy in 2 Siblings
Two siblings were diagnosed with Trichothiodystrophy, identified by brittle hair and low sulfur content.
research Application of XANES profiles to X-ray spectromicroscopy for biomedical specimens: Part II. Mapping oxidation state of cysteine in human hair
Perming and bleaching damage hair differently, with bleached hair having more cysteic acid in the cuticle.
research Relationship among Natures of Scalp Skin, Hair Follicle and Hair Shaft in Young Females.
Hair treatments can damage hair by changing its chemical content.
research Study on modification of rabbit hair fibers with L-cysteine
L-cysteine and ultrasound successfully improved rabbit hair fibers for industrial use.
research Efficacy and Safety of a Food Supplement Containing L-cystine, Serenoa repens Extract and Biotin for Hair Loss in Healthy Males and Females. A Prospective, Randomized, Double-blinded, Controlled Clinical Trial
The food supplement with L-cystine, Serenoa repens extract, and biotin safely reduced hair loss and improved hair growth in men and women.
research Dissecting hair breakage in alopecia areata: the central role of dysregulated cysteine homeostasis
Disrupted cysteine metabolism may cause hair breakage in Alopecia Areata, suggesting potential treatments like N-acetylcysteine.
research Morphologische und biochemische untersuchungen am Haar bei gestörtem Aminosäurestoffwechsel
Metabolic disorders can cause hair structure defects and growth issues, but amino acid levels in hair remain normal.
research Protein and amino acid composition of hair from mice carrying the naked (N) gene
The N gene affects the protein makeup of mouse hair.
research Hair as an Index of Protein Malnutrition
Hair cystine levels may indicate protein malnutrition, but more research is needed.
