research A review literature on rice water for hair mask
The rice water hair mask effectively moisturizes, strengthens, and protects hair.
research The swelling behaviour of hair studied through the structural change of keratin protein during the permanent waving treatment
Hair structure changes immediately during perm treatment, with initial damage partially restored later.
research Identification of reptilian genes encoding hair keratin-like proteins suggests a new scenario for the evolutionary origin of hair
Reptiles have genes similar to hair proteins, suggesting hair's genetic origins predate mammals.
research Identification of Novel Mutations in Basic Hair Keratins hHb1 and hHb6 in Monilethrix: Implications for Protein Structure and Clinical Phenotype
New mutations in hair keratin genes can change hair structure and cause monilethrix, with nail issues more common in certain gene mutations.
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 Discrete Nanoscale Distribution of Hair Lipids Fails to Provide Humidity Resistance
Hair lipids do not protect against humidity.
research Hair
Hair analysis can detect drug use but is costly and interpretation is complex.
research Special Biochemical Features of the Hair Follicle
Hair follicles have unique proteins that vary by species and are influenced by nutrition.
research The biology and genetics of curly hair
Curly hair is influenced by specific genetic variations.
research Age-associated thin hair displays molecular, structural and mechanical characteristic changes
Older thin hair is not just thinner but also has different shape, structure, and stiffness.
research The Catalog of Human Hair Keratins
Human hair keratins were cataloged, showing their roles in hair differentiation stages.
research Hair: Its structure and response to cosmetic preparations
Hair can be damaged by daily routines, but protein-based products can protect and improve it.
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 Genetic and biochemical aspects of the synthesis of keratin by hair follicles
Gene expression regulates keratin production for normal hair growth.
research Impact of Hair Damage on the Penetration Profile of Coconut, Avocado, and Argan Oils into Caucasian Hair Fibers
Different oils affect hair flexibility and strength, with their impact varying on whether hair is virgin or bleached.
research Photoinduced formation of thiols in human hair
UV exposure damages hair, increasing thiols and altering protein structure.
research Cyclin-dependent kinase inhibitors, p21waf1/cip1 and p27kip1, are expressed site- and hair cycle-dependently in rat hair follicles
p21waf1/cip1 and p27kip1 help in hair follicle differentiation in rats.
research Types of Hair Dye and Their Mechanisms of Action
Hair dyes vary in how long they last and how deeply they penetrate hair.
research Novel Type I Hair Keratins K39 and K40 Are the Last to be Expressed in Differentiation of the Hair: Completion of the Human Hair Keratin Catalog
K39 and K40 are the last keratins expressed in hair development, completing the hair keratin catalog.
research Hair Keratins and Hair Follicle–Specific Epithelial Keratins
Hair and follicle keratins differ in structure and expression, especially in cysteine content.
research Monilethrix: A Novel Mutation (Glu402Lys) in the Helix Termination Motif and the First Causative Mutation (Asn114Asp) in the Helix Initiation Motif of the Type II Hair Keratin hHb6
New mutations in hair keratin genes cause the rare hair disorder monilethrix.
research Extractable substances from human hair: a discussion about the origin of the holes
Holes in mature hair are likely caused by the removal of substances during hair care.
research Generation of iPS-derived model cells for analyses of hair shaft differentiation
Researchers created a mouse cell line to study hair growth and test hair growth drugs.
research Effect of Primary Biotin Deficiency on the Skin of Germ-Free and Conventional Mice Fed a Purified Biotin-Deficient Diet without Supplementation with Egg White.
Biotin deficiency causes severe hair loss and weight reduction in germ-free mice.
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 Understanding the Effect on Hair Fibers of Coloring and Bleaching Formulations Using High Pressure Differential Scanning Calorimetry (HPDSC)
Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.
research The structure of people’s hair
Hair's molecular structure is mostly consistent, but genetic differences affect lipid types, which could help diagnose diseases.
research Establishment of Heat‐Damaged Model for Hair
The model shows how heat damages hair, helping test hair care products.
research Human hair shaft proteomic profiling: individual differences, site specificity and cuticle analysis
Human hair proteins vary by individual, body site, and ethnicity, useful for forensics.
