Some oils can penetrate hair and reduce the stickiness between fibers, but mineral oil cannot.

This study found that injectable gelatin/metal/tea polyphenol double nanonetworks significantly accelerated wound healing in diabetic wounds by enhancing cell migration and providing anti-inflammatory and antioxidant properties, without detectable cytotoxicity in tests.

This abstract discusses the challenges and considerations of hair restoration surgery related to the skin's rich neuro-vascular supply and does not report new clinical results.

This study found that α-tocopheryl acetate is well absorbed through healthy skin, with absorption occurring through specific pathways and showing high affinity for small blood vessels.

This study found that dimethylpabamidopropyl laurdimonium tosylate, a quaternary ammonium surfactant, adsorbs onto human scalp hair with kinetic and isotherm behaviors fitting specific models, changing hair fiber wettability from hydrophobic to hydrophilic.

Minoxidil absorbs poorly through skin, with low risk of side effects at 1-2% concentration.

This study developed a theoretical model that suggests finasteride may completely inhibit 5AR type 2, but not sufficiently suppress type 1, leading to only partial reduction of dihydrotestosterone at clinical doses.

This study found that Transcutol P significantly enhanced the skin penetration of Finasteride in vitro, while cationic and anionic surfactants did not show such effects.

Liposomes can make the antiandrogen RU 58841 more effective for skin application by reducing absorption, increasing skin retention, and targeting sebaceous structures.

This review discusses the forms of selenium and sulfur in soil, their plant absorption, and risks of toxicity to livestock, emphasizing selenium's role in selenosis and sulfur's link to polioencephalomalacia in ruminants; it reports no new experimental results.

This review found that anti-aging peptides show promise in cosmeceuticals due to their targeted actions to rejuvenate skin, but challenges like peptide stability, penetration, and limited clinical data limit their current effectiveness.

This abstract provides information about the JAMA network's publications, services, and access options but contains no research findings.

This study highlights that restrictive abortion laws, financial barriers, and lack of sexual education are major issues in countries like Poland, the USA, and Italy, suggesting needed changes such as improved sex education, access to contraception, and international networks for legal abortion.

This study found that apple polyphenol extract, particularly oligomeric procyanidins, inhibited pancreatic lipase activity and reduced triglyceride absorption in both mice and humans.

This study demonstrated that hair follicles significantly expedite the absorption of caffeine through the skin compared to interfollicular pathways.

This review summarizes current knowledge on tight junctions in mammalian skin and their role in drug delivery and interaction with other barrier components, but reports no new experimental results.

This report describes an 11-year-old boy with Netherton syndrome who developed Cushing syndrome after using low-potency hydrocortisone ointment extensively, highlighting caution with long-term topical treatments in such conditions.

Some chemicals absorbed through the skin can cause serious health problems.

This review discusses the potential link between long-term transdermal exposure to sex hormones from antiperspirants and increased breast and prostate cancer rates, calling for further research to confirm this theory.

This study found that incorporating 0.5% TPGS into topical minoxidil solutions enhanced hair growth in mice, although increasing TPGS to 2% decreased effectiveness.

This study reported that microparticle-loaded emulsions containing caffeic acid achieved more homogeneous distribution and prolonged release in hair follicles, suggesting potential for effective folliculitis treatment.

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 highlights the historical and contemporary use of hair sutures in plastic surgery, noting their advantages such as favorable aesthetic outcomes, minimal tissue reaction, and cost-effectiveness, despite modern synthetic alternatives.

This study found that retinoic acid and a retinol complex formulation showed different permeation and compound localization in a skin equivalent model, with unique lipid changes observed with only the retinol formulation.

In this study, the safety of finasteride in rats varied depending on dosing time, while its effectiveness on prostate weight reduction remained consistent.

This study found that nanostructured lipid carriers with more soybean phosphatidylcholine provided better skin retention and follicular targeting for diphencyprone compared to other formulations and controls.

This review discusses the classification and regulation challenges of anti-ageing cosmetics in Europe and reports no new findings; it calls for increased transparency to help consumers make informed choices.

This study found that inoculating tea plants with arbuscular mycorrhizal fungi significantly improved growth, root morphology, and leaf nutrient levels, with Claroideoglomus etunicatum showing the most substantial effects.

This study found that using nanoporous silica entrapped lipid-drug complexes enhanced the solubility and bioavailability of dutasteride in beagle dogs.

This study concluded that placental mesenchymal stem cells from aborted fetal tissue may serve as an in vitro model for studying spontaneous abortion mechanisms and potential regenerative therapies due to their abnormal gene expression and differentiation capabilities.
