This study found that moisture sorption properties of wool and hair fibers from various animals were similar, despite different structural features, with sorbed water being more ordered than liquid water.

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 white hair fibers have lower lipid content and different water absorption dynamics compared to brown hair fibers, suggesting differences in their barrier functions.

This review discusses various nanoparticles used to enhance skin permeation and target delivery to skin organelles, but reports no new experimental results.

This study identified the location of the genetic locus for the slick hair coat trait in cattle on bovine chromosome 20, which may contribute to heat tolerance.

This review discusses the critical parameters for MALDI IMS sample preparation in skin analysis and highlights its applications in wound healing, neoplasia, and infection research, but reports no new clinical results.

This review discusses the potential of three-dimensional printed mesoporous scaffolds for drug delivery applications, particularly for bone cells and tissues, but reports no new clinical results.

This study found that a novel proniosomal gel formulation of CoQ10 improved antioxidant levels and provided better skin protection against UV radiation compared to a conventional CoQ10 gel in animal models.

This animal study found that biscuits fortified with zinc oxide nanoparticles improved growth, appetite, and hair growth in zinc-deficient rats more effectively than traditional zinc forms, without apparent toxicity.

Nanocarriers could improve how drugs are delivered through the skin but require more research to overcome challenges and ensure safety.

This study found that bleached hair showed optimal protein structural integrity and tensile strength at pH 5, with significant changes in cross-linking, water content, and diameter at more alkaline or acidic levels.

This study concluded that the follicular route is a significant pathway for delivering gentamicin through the skin, as demonstrated by higher drug permeation in non-plugged pig's ear skin compared to plugged skin.

This study found that paracellular transport significantly contributes to the intestinal permeability of minoxidil, suggesting its limited suitability as a Biopharmaceutics Classification System reference drug due to potential variability.

This systematic review found that exosomes and gut microbiota play a significant role in skin regenerative processes, suggesting that gut health is crucial for maintaining aesthetically healthy skin, and probiotic treatments may support traditional dermatological therapies for inflammatory skin diseases.

In this literature review, potential health risks of toxic chemicals commonly found in cosmetic products were linked to issues such as cancer, reproductive abnormalities, and skin diseases, highlighting concerns over ingredients like talc, parabens, and phthalates.

This review suggests that combining nanotechnology with herbal components in hair cosmetics may improve the delivery and effectiveness of treatments for issues like damage, dandruff, and hair loss.

This study found that overexpression of the SbbHLH85 gene in sweet sorghum increases root hair growth and Na+ absorption, but negatively affects salt tolerance.

This study found that enzymatic phosphorylation of hair keratin increased its capacity to adsorb cationic components like methylene blue and may have practical implications for hair care products.

This review discusses the potential of lecithin organogels for improving topical drug delivery and presents no new experimental results; the authors highlight their stability and low skin irritancy as advantages.

This study found that the HPCH-based formulation P-08–016 may facilitate finasteride deposition in the dermis, potentially offering an alternative to systemic therapy by minimizing systemic absorption.

This review outlines the histological structures of the skin, highlighting species and regional differences in dermal absorption and obstacles encountered in toxicological assessments due to epidermal thickness variability, contact dermatitis reactions, and stem cell vulnerabilities.

This study found that although soil and forage in Middle Paraíba, Brazil, contained normal to high copper levels, the surrounding bovine populations showed signs of copper deficiency likely due to antagonistic effects from high iron, zinc, and manganese levels.

In this study, the researchers developed and optimized a curcumin nanocrystal gel to enhance skin permeability, reporting improved dissolution properties and antiproliferative effects on cell lines, suggesting it as a promising topical delivery system.

This study found that hair treated with a supplemental hair care product showed significantly higher absorption, deeper penetration, and reduced dryness compared to untreated and water-treated hair, as measured with 3D Raman spectroscopy.

This study found that microspicule cosmetics with low-molecular-weight peptide complexes significantly improved skin whitening, pore condition, and skin barrier function over four weeks compared to a non-microspicule formulation.

This research letter observed that patients with severe atopic dermatitis showed normal serum cortisol levels after hospitalization despite continued use of potent topical corticosteroids, though poor adherence may lead to overestimations of actual medication use.

This study found that hair follicles contribute significantly to caffeine absorption shortly after topical application, with a faster absorption rate compared to the stratum corneum.

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 nanostructured lipid carriers with clobetasol propionate significantly enhance follicular drug delivery compared to commercial cream, and manual massage further doubles follicular retention.

This study reported that oleic acid-based nanovesicles improve follicular delivery and reduce side effects of minoxidil compared to traditional MXD lotions.
