This review discusses the structural and functional advances in understanding sulfotransferases and sulfatases, highlighting new insights into enzyme mechanisms and inactivation by clinically relevant aryl sulfamates, but provides no new experimental results.

In this study, researchers developed an optimized production process for the herbal tincture "Stimufit," intended for topical use in treating telogen alopecia, using 40% ethanol and a specific extraction method.

The researchers in this experimental study developed a thermodynamic model using the Peng-Robinson equation of state to optimize gas antisolvent system conditions for controlling finasteride particle size, aiming to reduce experimental trials and precisely identify precipitation pressures across different temperatures.

In this study, rabbit esophageal epithelial cells were found to produce K4 and K13 keratins in suprabasal cells, forming disulfide-crosslinked dimers that may support the physical stability of the esophageal lining.

This study reports that the metanephrine content was significantly higher in patients with alopecia areata compared to those without the condition.

In this research on cinnamon and virgin coconut oil hair tonics, F2 and F3 demonstrated stable physical properties and mild irritation potential, while formula 1 remained non-irritating but less stable regarding pH and viscosity.

This study found that chemically treated hair, particularly when subjected to both acid straightening and bleaching, experiences more significant structural damage when exposed to heat, highlighting key changes in both the internal and surface components of hair fibers.

This article reports preliminary findings on developing a stable emulsion-based semi-permanent hair dye by optimizing emulsification methods, surfactants, and conditioning ingredients.

This study concluded that bleach treatment partly transforms the hydrophobic top layer of human hair cuticles into a hydrophilic surface with clustered cysteic acid, visualized at the nano-scale using dynamic Chemical Force Microscopy.

This study found that finasteride effectively inhibits the enzymatic activity of human steroid 5 alpha reductase type II in newly established CHO cell lines.

This study found that the ethanolic extract of walnut fruit diaphragm significantly improved lipid profiles, reduced oxidative stress, and had anti-inflammatory effects in hyperlipidemic rats.

This review discusses the chemical processes involved in hair styling and straightening and reports no new results; the authors highlight pregnancy safety with hair treatments during pregnancy.

This study reports the purification of a specific sulphotransferase from rat liver that catalyzes the sulphation of minoxidil, potentially implicating it in minoxidil's bioactivation.

In this study, Urtica dioica L. infusions were used to replace water in k-carrageenan hydrogels, resulting in stronger networks with reduced syneresis and altered textural properties, and the highest antioxidant potential was achieved with specific infusion conditions.

This study suggests that finasteride-loaded polyvinyl alcohol/chitosan microspheres could be a promising embolic agent for benign prostatic hyperplasia, showing effective occlusion and sustained drug release in preclinical models.

This research investigated the design and synthesis of steroid-based compounds as aromatase inhibitors for breast cancer, finding that certain structural modifications significantly enhance their inhibitory potency.

Made 8 minoxidil samples; 1 cocrystal, 7 salts formed.

Human enzymes can detoxify harmful substances but might also increase their cancer risk.

This study found that ethosomes containing 30% ethanol slightly improved the targeting of dutasteride to hair follicles in vitro, with a higher targeting factor compared to dried ethosomes and controls after 24 hours on porcine skin.

This study found that antiandrogenic compounds in Curcuma aeruginosa, including germacrone, degrade rapidly at high temperatures but are more stable when solubilized in PEG-40.

This study found that in semi-coarse wool sheep of the Ukrainian Carpathian Mountain breed, changes in microflora and grease composition are linked to increased felting in wool, due to wetter, more alkaline fleece conditions that promote bacterial and mold growth and alter fatty acid balances.

Hair fibers may have a unique, non-protein sheath not previously identified.

This study reported a simple and validated gas chromatography method to accurately measure finasteride in tablets, showing equivalency to the official method with no significant differences.

This study found that straight permed hair retains more weight than virgin hair during burning at higher temperatures, with distinct differences in morphological changes observed through thermal analysis and microscopy.

This study found that using poly(ethylene imine) as a counterion reagent improved the colorability and shampoo fastness of bleached human hair when dyed with an acid dye.

This study found that rosemary essential oil can be incorporated into an aromatherapy massage cream, with different oil and water ratios affecting its physical properties.

This study developed a method using LC/APCI-MS to measure the activity of steroid 5α-reductase, applied to kinetic studies and inhibitory tests with Finasteride in a rat prostatic enzyme model.
