This study found that codeine incorporation in guinea pig hair varied with pigmentation and was highest in black hair, suggesting the role of eumelanins in drug binding.

This study identified seven potential enzyme inhibitors from a Polygonum cuspidatum extract using ultrafiltration combined with high-performance liquid chromatography. These compounds showed inhibitory activity against tyrosinase, α-glucosidase, and xanthine oxidase, with most discovered in this extract for the first time.

This study found that diphlorethohydroxycarmalol significantly increased prostaglandin $E_2$ synthesis in HaCaT human keratinocytes by upregulating COX-1 and COX-2 expression, suggesting potential benefits from elevated $PGE_2$ production.

This case report describes how real-time PCR rapidly identified Trichophyton mentagrophytes in a dog's dermatophytosis when traditional mycological methods were slower.

This study demonstrated that a photometric flow titration method using KMnO4 and minoxidil provided recovery rates of 97.6 to 102.8% for commercial samples, with relative errors of 3.5 to 4.0% compared to chromatographic procedures.

In this study, clinically used preoperative skin preparations with povidone iodine and chlorhexidine gluconate did not meet FDA log-reduction standards for bacterial bioburden in a porcine model, suggesting persistent infection risks.

This study found no evidence that the tested hair dye ingredients undergo hepatic metabolism to reactive oxidized metabolites in human liver microsomes and hepatocytes.

In this study, phenylthiocarbamide intake was associated with hair graying in rats, while switching to tap water led some rats to regain their original fur color, suggesting dietary factors influence pigmentation.

This study reports that citrulline, uniquely found in the inner root sheath of hair follicles, can be specifically detected with the carbamido diacetyl reaction, resulting in a bright orange color.

This study found that indole glycosides from Calanthe discolor Lindl. can significantly promote the proliferation of human hair follicle dermal papilla cells, potentially through upregulating specific growth factors.

This study suggests that G. sibiricum has potent aldose reductase inhibitory activity, primarily due to kaempferol rhamnosides, and may be further explored as a natural treatment for diabetes-related complications.

In this study, itraconazole was shown to accumulate in the deeper skin layers of guinea pigs after oral administration, suggesting this delivery method effectively targets infective organisms there.

In this study, PGD2 was shown to increase testosterone production in human keratinocytes through reactive oxygen species, suggesting potential benefits of antioxidants like N-acetyl-cysteine for AGA patients.

This study demonstrated that GP derivatization improves mass spectral analysis of spironolactone and its metabolites by reducing in-source fragmentation and enhancing signal clarity, laying the groundwork for future advancements in reaction optimization and quantitative assay development.

This study observed that Globularia alypum L. ointment significantly boosted hair growth in female albino rats, increasing hair length more than the control group after 20 days, without showing toxicity even at high doses.

This study found that the Padina arborescens extract and its component MOGG may prevent hair loss by inhibiting 5α-reductase activity, promoting cell proliferation, opening the KATP channel, and increasing PGE2 production in laboratory settings.

This study proposed a simple, rapid permanganometric method for determining minoxidil concentrations in pharmaceutical samples, offering comparable accuracy to chromatographic methods with recovery rates of 94.5 to 95.2%.

This study identifies various phytochemicals in Thuja orientalis bark, potentially aiding its botanical identification and quality standardization.

This study engineered a bioluminescent yeast strain responsive to androgenic chemicals, demonstrating rapid and sensitive detection suitable for high-throughput screening and environmental monitoring.

This study observed that carbon paste electrodes catalyze the electrooxidation of minoxidil more efficiently than other electrode types, with a detection limit of approximately 20 ng mL^-1.

This study developed a new permanganometric method for determining minoxidil in pharmaceutical formulations, offering a simple and rapid alternative to chromatographic procedures with recovery rates between 94.5% and 95.2%.

This case report discusses a young man's severe febrile illness mimicking leptospirosis or dengue, ultimately suggesting Gloriosa superba poisoning after hair loss led to the correct diagnosis.

This study found that inhaling toluene reduces core temperature in mice, with GABA receptors and neurosteroids involved at 4000 ppm, but different mechanisms contributing at 6000 ppm.

This study found that PIXE microanalysis effectively detected and quantified trace element changes in hair shafts, revealing a marked decrease in copper after treatment for green hair syndrome.

This study found that while the combination of oral propranolol and intradermal injections in guinea pigs led to psoriasiform changes, it did not fully mimic psoriasis.

This study found that the ethanolic root extract of Onosma dichroantha exhibits antioxidant activity and significant antimicrobial effects against 11 bacterial species.

This study reported that progesterone reduces cell death in hippocampal cultures following oxygen–glucose deprivation mainly through its conversion to allopregnanolone and the involvement of GABAA receptors.

This review discusses pyrene excimer nucleic acid probes for detecting biomolecules and protein-DNA interactions and reports no new experimental findings.

This study found that Galla chinensis solution significantly improved skin lesions and fungal eradication in dermatophytosis-infected dogs, showing over 85% efficacy in fungal removal after 14 days and outperforming the positive control treatment.
