research What factors play a role in unhealthy hair?
Environmental, chemical, mechanical, and personal health factors can all damage hair and contribute to hair loss or changes in hair quality.
research Impact of ultraviolet radiation‐induced damage to hair fiber integrity: A multi‐technique physicochemical characterization of surface and cortex properties
UV radiation damages hair similar to bleaching, but double bleaching causes more severe protein degradation.
research Abstracts: Reduction‐induced surface modification of human hair
Chemical treatments change hair surface properties, making it more hydrophilic and able to bind conditioners.
research Photoinduced formation of thiols in human hair
UV exposure damages hair, increasing thiols and altering protein structure.
research PREVENTION AND TREATMENT OF CHEMOTHERAPY-INDUCED ALOPECIA: A NARRATIVE REVIEW ON EMERGING TECHNIQUES
Scalp cooling and low-power light therapy show promise in reducing chemotherapy-induced hair loss but need more research.
research The structural implications of water hardness metal uptake by human hair
Human hair absorbs calcium and magnesium from tap water, affecting its structure and styling properties.
research Tensile properties of twisted hair fibers
Twisting hair weakens it, but strength can be recovered at low twist levels.
research Hair straightening and acute kidney injury: a case series from a medical toxicology service
Hair-straightening products with glyoxylic acid may cause kidney damage.
research Hair transparency decoding in Asia: From stylists’ perception to in vitro measurement
Higher hair luminosity and shine mean higher perceived transparency.
research Hair today, gone tomorrow: the degradation and conservation of archaeological hair fibers
Acidic sandy clay damages archaeological hair the most, while dry conditions preserve but make it brittle; silicone oil can help keep the hair flexible.
research Non‐invasive evaluation of hair interior morphology by X‐ray microscope
X-ray microscopy can non-invasively show hair structure changes after treatments, but it's less detailed than TEM and needs improvement.
research Amino Acid Content of Damaged Human Hair
High temperatures and certain chemicals can significantly change the amino acid content in human hair.
research Discovery of a sol–gel reinforcing the strength of hair structure: mechanisms of action and macroscopic effects on the hair
A small molecule can strengthen fine hair, making it more resistant and natural-feeling.
research Influence of functionalized silicones on hair fiber–fiber interactions and on the relationship with the macroscopic behavior of hair assembly
Functionalized silicones improve hair appearance, combing, and manageability.
research Innovations for cost-effective and eco-friendly solutions to combat chemotherapy-induced alopecia: a narrative systematic review
New cooling caps can help prevent hair loss from chemotherapy in a cost-effective and eco-friendly way.
research Evaluation of hair damage treated with oxidative hair dye under influence of conditioners agents
Conditioners improved hair protein retention and combing ease, with some providing thermal protection.
research Trichology to predict efficacy of scalp cooling: New pathologic insights besides encouraging clinical results.
Scalp cooling can effectively prevent hair loss during chemotherapy, improving patients' quality of life.
research 881 Ionizing radiation triggers dedifferentiation of outer root sheath cells into stem cell-like progenitors for hair follicle regeneration
research Holding Solutions, Conditions, and Additives to Optimize Hair Follicle Viability and Function
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 PROCEEDINGS OF THE INTERNATIONAL CONGRESS "SCIENCE, INFORMATIN, SPIRIT" 2007, PP 28-35 ELECTRO PHOTONIC ANALYSIS OF HAIR AND NON HAIR FIBERS AND INVESTIGATION OF DIFFERENT HAIR TREATMENTS
Hair properties change under electromagnetic fields and are influenced by individual characteristics and the environment.
research Advances in the Chemical Structure of the Hair Surface, Surface Forces and Interactions
Understanding hair surface properties is key for effective hair care products.
research Quasi-Static Torsional Deformation of Single Hair Fibers: Application of a Modeling Approach and Results from Cosmetic Treatments.
The research found that twisting hair fibers can show changes in stiffness and damage, and help tell apart different hair treatments.
research Novel insights into hair structure and the effects of chemical stressors on hair and skin using label-free advanced light microscopy
Chemical stressors damage hair structure but the skin's outer layer protects living cells.
research Effects of chemical structures of polycarboxylic acids on molecular and performance manipulation of hair keratin
A non-toxic formula using polycarboxylic acids strengthens and improves hair.
research Optical properties of hair: effect of treatments on luster as quantified by image analysis.
Treatments with certain oils and resins make hair shinier, while zinc oxide and synthetic sebum make it duller.
research Effects of ultraviolet B radiation on physicochemical properties of human hair shaft
UVB radiation changes the chemical makeup and dries out human hair but doesn't alter its appearance or texture.
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 Transmission electron microscopy staining methods for the cortex of human hair: a modified osmium method and comparison with other stains
The modified osmium method improves hair cortex staining for better visualization.
