research Kinetics and Equilibrium of Solute Diffusion into Human Hair
Hair absorbs molecules differently based on their size, charge, and love for water, and less at higher pH; this can help make better hair products.

30 / 1000+ results research Determination of Solute Diffusion Properties in Artificial Sebum
Diffusion in artificial sebum is mainly influenced by molecular size and is much faster than in skin lipids.
research Diffusion behavior of poly(ethylene imine) into keratin fibers using microspectrophotometry
PEI diffuses into hair at a constant rate, and urea speeds up this process.
research Determination of Free Chemical Potential for Finasteride Diffusion through SDS Micelle Suggested as Alternative Living Membrane System
Finasteride diffuses spontaneously through SDS micelles, suggesting they can replace living cell membranes.
research <title>In-vitro and in-vivo study of dye diffusion into the human skin and hair follicles</title>
Dyeing hair can help target and destroy hair follicles selectively.
research Development of a Two-Dimensional Model for Predicting Transdermal Permeation with the Follicular Pathway: Demonstration with a Caffeine Study
Researchers developed a model that shows hair follicles increase skin absorption of caffeine by 20%.
research External lipid function in ethnic hairs
African hair has the most lipids, while Caucasian hair is more hydrated and stronger.
research In-Silico Modelling of Transdermal Delivery of Macromolecule Drugs Assisted by a Skin Stretching Hypobaric Device
The simulation showed that hypobaric pressure improves drug delivery through the skin, but stretching alone doesn't fully explain the increase.
research Skin permeation of curcumin nanocrystals: Effect of particle size, delivery vehicles, and permeation enhancer
Smaller curcumin nanocrystals penetrate skin better, but additives and particle size affect absorption and accumulation.
research Preparation, Optimization, In vitro Evaluation and Ex vivo Permeation Studies of Finasteride loaded gel Formulations Prepared by using Response SurfaceMethodology
The combination of propylene glycol and Tween® 80 improves finasteride gel effectiveness.
research Investigation of in vitro and in vivo skin permeability using laser scanning microscopy
Nanoparticles in sunscreen are generally safe as they stay on the skin's surface.
research A Composite Model for the Transport of Hydrophilic and Lipophilic Compounds Across the Skin: Steady-State Behavior
The model better predicts how water-loving and fat-loving substances move through the skin by including tiny pores and hair follicle paths.
research Transdermal Permeation of Drugs in Various Animal Species
Pig skin is a good substitute for human skin to measure drug absorption, but differences in skin structure and enzymes across species must be considered.
research Chemical and photo-oxidative hair damage studied by dye diffusion and electrophoresis.
Chemical treatments and light exposure damage hair proteins.
research Comparison of artificial sebum with human and hamster sebum samples
Artificial sebum L closely mimics human sebum for drug delivery research.
research Moisture sorption/desorption of protein fibres
Internal lipids in keratin fibers, like wool and hair, reduce water absorption and release.
research Global behavior of solutions in a chemotaxis model for alopecia areata with signal-dependent sensitivity
Sparse hairless patches can develop and stabilize in alopecia areata under certain conditions.
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 Influence of Chemical Permeation Enhancers on the in vitro Skin Permeation of Minoxidil through Excised Rat Skin: A Mechanistic Study
Urea, eucalyptus oil, and menthol improve minoxidil skin absorption.
research An Improved Face Image Restoration Method Based on Denoising Diffusion Probabilistic Models
The new method improves facial image restoration quality and face recognition accuracy.
research Contribution of the Hair Follicular Pathway to Total Skin Permeation of Topically Applied and Exposed Chemicals
The hair follicle pathway significantly affects how easily water-loving chemicals pass through the skin.
research Investigation of drug partition property in artificial sebum
The conclusion is that measuring how drugs partition into artificial sebum is important for predicting their delivery into hair and sebaceous follicles, and it provides better information than traditional methods.
research Diffusion properties of model compounds in artificial sebum
Different compounds move through artificial sebum at different rates, which can help choose the best ones for targeting hair follicles.
research Exogenous and endogenous lipids of human hair
Removing external lipids from hair reduces moisture and increases strength, while removing internal lipids decreases water permeability.
research Heat Enhanced Follicular Delivery of Isotretinoin to the Skin
Applying heat with certain chemicals can greatly improve how well isotretinoin gets into the skin through hair follicles.
