30-60 / 1000+ resultsresearch Photo‐protective effect of cuttlefish ink melanin on human hair
Cuttlefish ink melanin protects hair from UV damage.
research Effective Penetration of the Oxidized Keratin‐Rebonding Materials Into Hair Shafts Based on Charge Conversion
Charge-conversion chemistry improves hair-rebonding by enhancing penetration and strength.
research Repeatable Perming via Thiol–Michael Click Reaction: Using Amide Derived from Maleic Acid and Cystine
A new perming method is less damaging to hair and works as well as traditional methods.
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 Development and optimization of biotinoyl tripeptide-1 loaded solid lipid nanoparticles for protection against heat induced hair damage
This study developed and optimized biotinoyl tripeptide-1 (BTP)-loaded solid lipid nanoparticles (SLNs) to protect hair from heat-induced damage. Using a Box-Behnken design, the researchers optimized the formulation, achieving a particle size of 207.3 nm, PDI of 0.297, zeta potential of -10.6 mV, and entrapment efficiency of 46.2%. Hair samples treated with BTP-SLNs showed improved cuticle integrity, reduced microfibrillary separation, and increased thermal resistance compared to untreated samples. The protective effects are attributed to lipid barrier formation and keratin matrix stabilization, indicating BTP-SLNs as a promising approach for enhancing thermal protection in hair care products.
research A discrete transition zone between cuticle and cortex layers of a human hair fibre: changes observed in the presence of breast cancer
Breast cancer alters specific molecular structures in hair, which revert after cancer removal.
research An Integrated Analysis of Cashmere Fineness lncRNAs in Cashmere Goats
lncRNA XLOC_008679 and gene KRT35 affect cashmere fineness in goats.
research Investigation of the Changes in the Hair Cuticle Due to Chemical Degradation
Chemical treatments severely damage hair cuticles, especially in previously treated hair.
research Acidic and basic hair/nail ("hard") keratins: their colocalization in upper cortical and cuticle cells of the human hair follicle and their relationship to "soft" keratins.
Hair and nail cells share similar proteins, indicating a common differentiation pathway.
research Smad4-dependent desmoglein-4 expression contributes to hair follicle integrity
Smad4 is important for healthy hair follicles because it helps produce a protein needed for hair to stick together and grow.
research Activation of the integrated stress response in human hair follicles
Blocking the Mitochondrial Pyruvate Carrier causes stress in hair follicles, which can be reduced by an ISR inhibitor.
research Integrating herbal components into pharmaceutical formulations for hair woes
Herbal ingredients like aloe vera and hibiscus can help with hair problems like hair loss and dandruff.
research Melatonin promotes Cashmere goat (Capra hircus) secondary hair follicle growth: a view from integrated analysis of long non-coding and coding RNAs
Melatonin helps Cashmere goats grow more hair by affecting certain genes and cell pathways.
research Distribution of Glycolipid and Unsaturated Fatty Acids in Human Hair
Human hair has more unsaturated fats inside than on the surface, and certain lipids may help bind the outer and inner layers together.
research Beyond goosebumps: Does the arrector pili muscle have a role in hair loss?
The arrector pili muscle might play a role in hair loss and needs more research to understand its impact.
research Heat‐damaged evaluation of virgin hair
Heat damages hair, with Asian hair losing more protein than Caucasian hair.
research Curly hair: measured differences and contributions to breakage
Curly hair breaks more easily, especially with chemical treatments, but simpler grooming reduces breakage.
research Effect of equilibrium pH on the structure and properties of bleach‐damaged human hair fibers
Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.
research HAIR | Overview
The document explains how hair is studied in forensics to identify its source and its role in criminal investigations.
research In-Situ Tensile Testing of Hair Fibers in An Environmental Scanning Electron Microscope (ESEM)
Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.
research Ultrasonic and Infrared Hair Treatment: Scientific Justification and Application Practice
Ultrasonic and infrared treatments can improve hair strength and appearance with minimal damage.
research An Integrated Transcriptome Atlas of Embryonic Hair Follicle Progenitors, Their Niche, and the Developing Skin
The study identified unique genes in hair follicle cells and their environment, suggesting these genes help organize cells for hair growth.
research Lamins in development, tissue maintenance and stress
Lamins are vital for cell survival, organ development, and preventing premature aging.
research Reactive keratin derivatives: A promising strategy for covalent binding to hair
Modified keratin binds better to hair, especially bleached hair.
research Chapter 4 Cytomechanics of Hair
Hair's strength and flexibility come from its protein structure and molecular interactions.
research Structural and biochemical changes underlying a keratoderma-like phenotype in mice lacking suprabasal AP1 transcription factor function
Inhibiting AP1 in mice skin causes structural changes and weakens the skin barrier.
research Hair Morphology in Androgenetic Alopecia
Abnormal cuticle and hair shaft medulla cause hair loss in androgenetic alopecia; sonography helps diagnose and manage it.
research The G60S Connexin43 Mutant Regulates Hair Growth and Hair Fiber Morphology in a Mouse Model of Human Oculodentodigital Dysplasia
The G60S Connexin43 mutation causes hair growth issues and poor hair quality in mice, similar to human ODDD patients.
research Investigation of hair shaft in seborrheic dermatitis using atomic force microscopy
Hair from people with seborrheic dermatitis is thicker scaled, more damaged, and thinner than healthy hair, and atomic force microscopy can help monitor the condition.
