research Biology of Human Hair: Know Your Hair to Control It
Understanding hair biology is key to developing better treatments for hair and scalp issues.
research Charge Density Alterations in Human Hair Fibers: An Investigation Using Electrostatic Force Microscopy
The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.
research Simultaneous RP-HPLC-DAD Determination of Dansyl Amino Acids in Chemically Treated Human Hair
A new method accurately measures amino acids in treated hair, showing bleaching reduces amino acids while protein treatments increase them.
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 Hair as an Index of Protein Malnutrition
Hair cystine levels may indicate protein malnutrition, but more research is needed.
research Keratin
Understanding how keratin structures in hair are arranged and interact is key for creating methods to extract and purify them.
research 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 Effects of Ultraviolet Radiation on the Soluble Proteins of Human Hair
UV radiation increases protein loss from hair and reduces hair protein quality.
research Reconnection Of Cysteine In Reduced Hair With Alkylene Dimaleates Via Thiol-Michael Click Chemistry
A new method using 1,4-n-butylene dimaleate effectively repairs and strengthens damaged hair.
research Reduction Mechanism of L-Cysteine on Keratin Fibers Using Microspectrophotometry and Raman Spectroscopy
L-cysteine slows down the breaking of bonds in hair due to electrostatic interactions.
research Effect of Ethnicity and Treatments on In Situ Tensile Response and Morphological Changes of Human Hair Characterized by Atomic Force Microscopy
Different ethnicities and treatments affect human hair strength and structure.
research A Keratin Fiber Sheath
Hair fibers may have a unique, non-protein sheath not previously identified.
research Physical and Mechanical Properties of the Hair Shaft: A Review of Measurement Techniques to Verify the Efficacy of Cosmetic Products
Different techniques measure hair properties to ensure cosmetic products work.
research Effect of Protein Hair Straightener on Hair Shaft by Scanning Electron Microscopy
Protein hair straighteners damage the hair more than hair dyes.
research Cysteine Prevents the Reduction in Keratin Synthesis Induced by Iron Deficiency in Human Keratinocytes
Cysteine helps maintain keratin production in skin cells even when iron is low.
research Environmental and Cosmetic Factors in Hair Loss and Damage
Environmental and cosmetic factors, including heat, chemicals, and sun exposure, can cause hair loss and damage.
research Direct Observation of Hair Components Involved in Formation of Permanent Waves
Microfibrils are key for permanent waves, and hydrolyzed keratin improves wave formation and hair condition.
research Properties of Partially Extracted Hairs and Their Degradability by Proteases
Mf-rich hair degrades more than Ma-rich hair, especially with Proteinase K.
research Exogenous Factors in Hair Disorders
Outside factors like grooming, chemicals, and the environment can damage hair and cause disorders.
research Proteins as Hair Styling Agents
Proteins like BSA and keratin can effectively style hair and protect it, offering eco-friendly alternatives to chemical products.
research PH Dependence of the Coiled-Coil Structure of Keratin Intermediate Filament in Human Hair by 13C NMR Spectroscopy and the Mechanism of Its Disruption
Keratin structure in hair is stable at pH 5-6 but disrupts between pH 6-7.
research Enzymatic Method for Assessing Hair Damage with Reduction and Subsequent Oxidation
Permed hair degrades faster and shows more damage after protease treatment compared to untreated hair.
