This research observed that hairless guinea pig dermal fibroblasts were more sensitive to a toxic exposure than human dermal fibroblasts, suggesting that guinea pigs might serve as an intermediate model for translating in vitro findings to whole organisms.

This study found that UVA and UVB exposure increased hydroquinone and sunscreen absorption in nude mouse skin, with less absorption enhancement observed in more lipophilic sunscreens.

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

Different cells affect hair follicle blood vessels, endothelial cells react differently to inflammation and oxidized fats, and prasugrel better protects heart vessels during a procedure than clopidogrel.

This study found that Schistosoma mansoni cercariae stimulate epidermal keratinocytes in mice, initiating pro-inflammatory responses and barrier repair mechanisms akin to those in wound healing.

This study found that coadministering minoxidil with tretinoin cream increased minoxidil absorption nearly threefold in healthy males, attributed to increased stratum corneum permeability.

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.

Prasugrel is better than clopidogrel at preventing heart damage and improving blood flow in small heart vessels during heart artery procedures.

This study presented a new two-dimensional model that successfully predicts transdermal permeation of caffeine, highlighting the significant role of the follicular pathway in increasing systemic bioavailability.

This review suggests that skin may largely protect itself from CYP-generated reactive metabolites due to higher conjugating enzyme activities, while highlighting limitations in modeling human skin metabolism experimentally.

This review discusses the current medical treatments for hepatocellular carcinoma, noting that while new local therapies show high response rates, their true impact on patient survival is uncertain.

This review discusses current treatment strategies for alopecia and highlights the potential of lipid-based nanoparticles to improve drug delivery to the scalp and hair follicles, noting their ability to enhance skin penetration and drug stability while outlining associated challenges and the need for further research.

This review highlights that exosomes from adipose-derived stem cells, particularly those enriched with circ-Ash1l, can inhibit ferroptosis and reduce UVB-induced skin aging by delivering GPX4-promoting signals to damaged cells, thus offering a potential regenerative therapy for photoaged skin.

This study reports that ritlecitinib, when used for up to 24 months in patients aged 12 and older with alopecia areata, has an acceptable safety profile, with a similar proportion of adverse events in both ritlecitinib and placebo groups in the placebo-controlled cohort.

Recent hair loss research shows some progress, especially in understanding male pattern baldness, but effective treatments for many types of hair loss are still lacking.

This study observed that in children who unintentionally consumed high-dose oral minoxidil, 65% developed hypertrichosis, predominantly on the face, and 15% experienced mild systemic side effects.

This study found that radiofrequency microneedling significantly enhanced the absorption of topical triamcinolone acetonide, with insertion depth being more influential than RF energy levels.

This research highlights that various environmental pollutants, including particulate matter, tobacco smoke, and heavy metals, can significantly affect hair follicle health, linking them to conditions like alopecia areata and androgenetic alopecia, underscoring the need for further study in this area.

This study found that a new alcohol-free minoxidil hydrogel formulation showed comparable in vitro efficacy and skin absorption to the commercial minoxidil product for treating androgenetic alopecia.

This review discusses the safety and potential adverse events of microneedling as both a medical and consumer product, noting the need for further understanding; no new clinical results are presented.

In this study, brief ultrasound exposure reduced the follicular contribution to hydrocortisone absorption while significantly increasing total skin permeability, likely due to removal of the upper stratum corneum.

This study found that domestic temporary hair dyes may pose a health risk due to their cytotoxic effects on human red blood cells and NIH/3T3 cell lines.

This study presents a method for directly measuring the solubility of solid chemicals in the skin's stratum corneum under various humidity conditions, emphasizing its importance for dermal drug delivery and chemical safety assessments.

This study reviewed 54 articles to examine how continuous exposure to air pollution causes hair damage, hair loss, and scalp conditions due to oxidative stress and inflammation, and highlighted anti-inflammatory substances that could mitigate these effects.

In this study, radiofrequency microporation significantly improved topical minoxidil delivery and hair regrowth in a mouse model of androgenetic alopecia, with minimal systemic exposure compared to oral administration, suggesting it could be a promising needle-free option for topical therapy.

This study reported that exposure to 1,763 MHz radiofrequency radiation stimulated hair growth in vitro by inducing insulin-like growth factor-1 expression in cultured human dermal papilla cells.

This review discusses the links between particulate matter exposure and skin diseases, highlighting oxidative stress and inflammation as key mechanisms; it reports no new clinical results.

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 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.

In this study, magnesium was observed to penetrate human skin, with hair follicles significantly aiding this process depending on the concentration and duration of exposure.
