This study observed that ethyl glucuronide (EtG) concentrations in hair decreased significantly during an abstinent period, suggesting possible wash-out effects or other factors affecting EtG levels.

This study found that patients with decreased kidney function had significantly higher hair levels of ethyl glucuronide compared to healthy individuals, suggesting these results should be cautiously interpreted.

This study reported that oral administration of Aucklandia lappa Decne. extract significantly promoted hair growth and increased the number of hair follicles in hair-removed mice compared to controls.

In this study, the researchers reported that while both propylene glycol and sodium lauryl sulfate enhanced finasteride's skin deposition, ethanol was the only effective enhancer of finasteride's permeation through the skin.

This study found that hair growth gel and tonic containing red grape seed extract were physically and chemically unstable under high temperature and humidity conditions over 30 days.

In this study, finasteride altered acute ethanol withdrawal severity differently in male and female mice, highlighting sex differences in sensitivity to changes in neurosteroid levels.

This study examined the stability of two 5α-reductase inhibitors in Tectona grandis extracts, finding that they are more stable in acidic environments and degrade rapidly under heat and light unless protected, suggesting the need for careful storage when developing anti-hair loss medications.

This study found that ethanol-containing formulations significantly increased minoxidil retention in the stratum corneum and appendages initially, while a propylene glycol-rich formulation enhanced deeper skin penetration over time.

This study found that using monoolein cubic phase nanoparticles with an entrapped hydroxypropyl β-cyclodextrin/minoxidil complex increased minoxidil skin permeation, but minoxidil retention in the skin was higher with a traditional solution.

This study assessed minoxidil solubility in propylene glycol and water mixtures, comparing cosolvency models and examining thermodynamic properties, without reporting new clinical results.

This study focused on developing a nanoemulsion-based gel for delivering minoxidil, aiming to enhance its contact time with the scalp and potentially improve skin absorption compared to conventional topical solutions.

This study found that platycodon ethanol extract showed potential as a natural ingredient for hair loss prevention by increasing radical scavenging ability, inhibiting inflammation, and affecting DHT generation in laboratory experiments.

This study developed a liquid chromatography with tandem mass spectrometry method to detect sex hormones in health supplements from Hanoi, Vietnam, finding three out of 16 samples contained sex hormones, including banned testosterone at low levels (~0.5 mg/kg).

This study found that an optimized microemulsion for minoxidil with high solubility, permeation flux, and skin deposition can be achieved with specific low and high levels of certain surfactants and co-solvents.

This study found that excipients significantly influence the effectiveness of curcumin nanocrystals in dermal applications, enhancing or hindering hair follicle targeting and passive diffusion based on their selection.

This study found that penetration enhancer-containing vesicles significantly improved minoxidil delivery to the skin compared to traditional liposomes and penetration enhancer-containing ethanolic solutions, with deformability linked to enhanced deposition.

This study found that papain/bisulfite disintegrates human hair cuticles by dissolving the endocuticle, potentially accelerated by ethanol's removal of cell membrane material.

This study found that the EtOAc extract of Tridax procumbens aerial parts significantly inhibited rat paw edema and COX enzyme activity, suggesting its potential anti-inflammatory properties.

This study found that Cuscuta reflexa extracts promoted hair regrowth and follicular proliferation in cyclophosphamide-induced hair loss in male rats.

This study investigated the effects of the 60% alcohol extract from Alnus sibirica and its active compound, oregonin, on hair health, observing anti-oxidative and anti-apoptotic benefits in human hair dermal papilla cells exposed to oxidative stress, suggesting potential as natural materials for hair loss prevention.

In this study, EPC-K, a compound with antioxidant and moisturizing effects, was found to decompose significantly under certain conditions, impacting its stability in quasi drug hair-growing products.

Hair follicles could be used for targeted drug delivery, with liposomal systems showing promise for this method.

This study found that ethanolic extracts of Microsechium helleri showed notable antioxidant, hypoglycemic, and cardioprotective activities, while chloroformic extracts exhibited significant anti-inflammatory effects in experimental models.

In this study, topical application of tonic preparations containing 5% ethanol extract of Phyllanthus niruri to shaved mice showed potential as a hair growth enhancer, as indicated by observations of increased hair length and weight over a 21-day period.

In this study, researchers observed that dandruff involves altered keratinocyte activity and a low-grade inflammatory response characterized by increased interleukin-17-producing T-cells and CCL17 levels, but without significant changes in immune cell populations or skin barrier lipids.

This study successfully developed and optimized ethanol-free microemulsion systems for the transdermal delivery of finasteride, showing that the predicted optimal formulations had physicochemical characteristics close to estimated values, without significant damage to treated hair fibers.

This study explored the in vitro skin penetration of two compounds from Tectona grandis leaf extract used for standardization and found that compound 1 penetrates more efficiently than compound 2, especially with a propylene glycol enhancer.

In this study using a porcine skin model, the researchers reported that smaller curcumin nanocrystals in xanthan gum gel showed higher passive skin penetration, while larger particles achieved deeper follicular accumulation.

The researchers found that plant extracts from Papaver rhoeas L., Clitoria ternatea L., and Carthamus tinctorius L. are effective natural cosmetic dyes, offering intense and stable colors without cytotoxicity.

This study found that ethanol extract of Tubtim Chumphae rice bran downregulates SRD5A gene expression, similarly to finasteride, suggesting potential use as an anti-hair loss product.
