In this study, researchers found that the lipid composition in hair significantly affects water diffusion and may explain differences in dyeing and cosmetic treatment responses between Asian and European hair, with CP2 fibers having more lipids than CP3 fibers.

This study found that the uptake of molecules by hair is influenced by both hydrophobic and ionic charge interactions, with binding affinity decreasing as pH approaches the solute's dissociation constant.

This study found that commercially available dyes penetrate up to 1.2 mm into human skin, with Indocyanine Green binding to cell proteins and showing a shift in absorption peak.

This study found that diffusion coefficients of chemicals in artificial sebum are significantly higher than those in stratum corneum lipids, suggesting the hair follicle may significantly contribute to transdermal permeation.

In this study, extracting internal lipids from Caucasian hair fibers led to decreased water permeability, influenced by the fluidity of lipids.

This study found that African and Caucasian hair contain the most lipids, and depletion of these lipids leads to less water retention and increased water desorption, with Caucasian hair showing improved breaking tenacity after lipid extraction.

This study extended a skin diffusion model to include a porous pathway, effectively explaining the permeability of both polar and lipophilic solutes through the stratum corneum.

Hair removal methods damage the skin barrier and affect substance penetration.

This in vitro study found that opiate diffusion was more pronounced in damaged hair fibers than in undamaged ones, with high opiate concentrations detected in fiber centerpieces.

This study found that lipid extraction increased water diffusion in wool and hair fibers; the effect was more pronounced in hair, indicating lipids are crucial for water permeability.

In this study, ethosomes were found to significantly enhance the transdermal penetration and skin accumulation of finasteride compared to liposomes and other control solutions.

This study found that minoxidil was released 50% less from creams than from lotions, with a similar release profile across different lotion formulations, suggesting a specific vehicle composition for topical use.

This study explored the in vitro skin penetration of two compounds from Tectona grandis leaf extract used for standardization and found that compound 1 penetrates more efficiently than compound 2, especially with a propylene glycol enhancer.

The researchers reported that caprylic acid effectively enhances the permeability and diffusion of minoxidil through rat skin compared to other penetration enhancers.

This study found that white poplar wood sawdust effectively removed up to 92.12% of thallium ions from contaminated water in laboratory conditions, demonstrating its potential as a low-cost adsorbent for reducing toxic thallium levels.

This study developed a novel hydrogel dressing, QL@MAB, which facilitates accelerated healing of infected diabetic wounds in rats by offering prolonged drug release, water retention, and adaptive drug delivery in response to high glucose levels in the wound environment.

In this study, researchers developed and validated a rapid and robust chromatographic method to assess the concentration of Minoxidil and Finasteride in a new topical formulation for alopecia, demonstrating its ability to distinguish between different types of formulations using in vitro diffusion data.

This study found that age-related hair thinning in Caucasian women over 50 involves significant structural changes within the hair follicle, suggesting an "aged hair program" rather than just producing thinner hairs.

This study found that, despite the unchanged total level of 18-MEA, deletion of the Sox21 gene disrupts its attachment to the hair cuticle, increases cholesterol sulphate levels, and differentially affects ceramide composition.

This study concluded that Wnt/β-catenin signaling, through Shh and Bmp pathways, is crucial for determining hair follicle fate in embryonic epidermal development.

This paper introduces the first computational model of male baldness that simulates hair loss using the Hamilton-Norwood classification and has been deemed plausible for clinical use by a dermatologist.

This study found that minoxidil forms a reservoir in the skin, allowing sustained drug delivery even after cleansing, while propylene glycol does not.

This study found that cold air can effectively preserve the epidermis when using an 810 nm diode laser, but it is slightly less effective than a chilled sapphire window in dark-haired pigmented pigs.

In this study, adding TPGS to a minoxidil formulation improved local retention and reduced systemic absorption in certain solvent mixes, particularly with a balance of alcohol and PEG 400.

This study demonstrated that dyeing can enhance the absorption coefficient of hair follicle tissues for selective photodestruction within human skin and hair follicles.

This study demonstrated that urea significantly accelerates the diffusion of poly(ethylene imine) into bleached human hair by increasing the diffusion coefficient twofold.

This study found that Mueller-Hinton Agar performed better than Dermasel Agar for antifungal susceptibility testing of feline dermatophytes, providing reliable susceptibility data for effective antifungal therapy.

This study found high levels of toxic heavy metals in water sources of mining communities in Abakaliki, Nigeria, posing potential health risks including Parkinson's and Alzheimer's diseases.

In this study, researchers developed a new self-administered finasteride delivery system using powder-carrying microneedles that improved hair growth efficacy and addressed safety concerns compared to topical finasteride gel by allowing sustained intradermal release of the drug for three days with a single application.

The study found that the Marangoni effect causes the uneven wetting of surfactant-coated hair due to the surfactant moving into the water.
