The document says biodegradable cosmetics and packaging are better for the environment and user experience.

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 study developed a precise and reliable UV spectrophotometric method for determining finasteride concentration in bulk and tablets, demonstrating strong linearity and accuracy.

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.

This study demonstrated that combining l-cystine and thiamin in a formulation may protect against UV-induced damage in growth-limited human epidermal keratinocytes in vitro.

This study developed and validated a simple, cost-effective UV–Visible spectrophotometric method for estimating finasteride in pharmaceuticals, demonstrating good linearity, accuracy, precision, and sensitivity according to ICH guidelines, making it suitable for routine quality control.

This study found that ultraviolet radiation negatively affects hair follicle functions in human scalp skin, and caffeine application may provide some protective effects against this damage.

This study found that minoxidil absorption through the skin increased with longer contact times, reaching over 75% of the maximum absorption within four hours.

This study found that using a combination of iontophoresis and liposomal delivery facilitated the effective intradermal administration of superoxide dismutase in rats, reducing oxidative skin damage from UV exposure.

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 found that a hydro-alcoholic extract of Roselle petals may reduce free radical production during UV-induced photodecomposition of antibiotics, potentially offering protective benefits for patients using similar topical antibiotics.

This manuscript suggests that exogenous hydrogen peroxide is a primary risk factor for higher incidence of cutaneous melanoma in swimmers, with UV radiation playing a secondary role.

This study found that UV laser-induced fluorescence spectroscopy can effectively differentiate between types of alopecia in patients, showing a high correlation between blood circulation levels and tissue autofluorescence intensity.

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 examined the pharmacokinetics of finasteride in pigs and found that ketoconazole coadministration affected its distribution across various plasma compartments, bile, and urine.

This study found that arbuscular mycorrhizal fungus inoculation and shading improved tea seedlings' growth, nutrient absorption, and stress resistance by enhancing root biomass and regulating phytohormone levels and gene expression.

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.

This study found that topically administered spironolactone in healthy volunteers resulted in no detectable systemic absorption or changes in related hormone levels over 72 hours, indicating local effect only.

This study reported that the calculated and experimental electronic and vibrational properties of minoxidil were in good agreement, providing detailed insights into its molecular structure and thermal behaviors.

This review discusses the use of caffeine in cosmetics for its fat-reducing, antioxidant, and hair growth properties, but reports no new research findings.

This study found that the 11R-No. 10 peptide, delivered transdermally, significantly inhibited melanogenesis and produced a whitening effect in a UV-induced sun-tanning guinea pig model without cytotoxicity.

New method measures minoxidil concentration faster, more accurately, and automatically.

This study developed a reliable HPLC-UV/Vis method to determine aluminum phthalocyanine chloride in skin, supporting its use in skin permeation studies for photodynamic therapy of cutaneous tumors.

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 flutamide emulgels with 1% Transcutol P enhanced percutaneous absorption through rat skin more effectively than other formulations tested.

This study developed three spectrophotometric methods to effectively measure finasteride in bulk and tablet forms, providing accurate results that align closely with labeled claims.

Pollution exposure speeds up hair damage.

This study reported the development of a novel and reliable liquid chromatographic method to measure testosterone and epitestosterone in human urine, offering sensitive detection for doping control.

This study found that Silibinin-loaded polymeric micelles significantly protected human hair from UV-B induced structural and chemical damage by preventing increases in roughness and reducing protein loss.
