This study found that Equisetum arvense, or horsetail, water extracts prepared with polyethylene glycol in an ultrasonic bath yielded the highest levels of phenolic compounds, such as hydroxycinnamic acids and flavonoids, indicating that this method improves the release of biologically active substances.

This study found that formulations containing saccharide isomerate significantly improved scalp flaking, sebum secretion, and transepidermal water loss compared to placebo in an adult Chinese population with dandruff.

In this study, researchers reviewed the progress and challenges in using hydrogels for 3D printing in biomedical applications, highlighting advancements in structural complexity, and identifying ongoing issues like resolution improvement, cell viability, and ethical concerns for clinical use.

In this study, prolonged high-dose steroid treatment in rats caused several pathological changes, some of which regressed, particularly improvements in mammary gland tumors and pituitary-related symptoms, after stopping treatment.

This review highlights that Tremella fuciformis polysaccharide exhibits various bioactivities, such as antioxidant and immune-modulating effects, and explores its potential applications in food, pharmaceutical, and cosmetic industries.

This study developed a faster method to analyze fatty acid ethyl esters in human hair, potentially distinguishing alcohol consumption levels more efficiently.

This study found that ethanol's ability to block long-term potentiation in rat hippocampal slices is influenced by neurosteroids that enhance GABA A receptor activity.

This study found that the dehydroepiandrosterone hydroxylating enzyme system in hair follicles is similar to the liver monooxygenase system, sharing characteristics such as inhibition by carbon monoxide and dependency on NADPH.

This study found that hair membrane fluidity is low in the cuticle but high in the cortex and medulla, with treatments like ionic surfactants and oleic acid increasing fluidity in hydrated hair; however, dehydration significantly reduces fluidity throughout the hair.

This review examines ethosomal structures and their mechanisms as skin delivery systems, outlining preparation methods and applications but presents no new experimental findings.

This study found that two new progesterone derivatives showed higher antiandrogenic effects and 5α-reductase inhibition than finasteride in hamsters, particularly reducing seminal vesicle weight and flank organ size.

This study found that palmitoylethanolamide may stimulate allopregnanolone synthesis and reduce oxidative stress in astrocytes through PPAR-α activation, suggesting a neuroprotective role.

This review discusses the current research and development of mannosylerythritol lipids, particularly focusing on their potential commercial applications in cosmetics; it reports no new results.

This study found that ultrasonically depolymerized ι-carrageenan from Solieria chordalis yields low-molecular-weight fractions that maintain fibroblast viability and show no cytotoxicity, suggesting potential for safe use in human medicine.

This study investigated the physical stability of hair tonic formulations made from ethanol extract of cayenne pepper leaves, finding that formulations with specific concentrations of propylene glycol and ethanol had good physical stability.

This review discusses temporary chemical hair removal methods involving thioglycolates and other compounds but reports no new clinical findings; the authors highlight interest in natural-based substances.

This study found that phytosterols extracted from moringa seed oil may act as potential anti-alopecia agents by inhibiting the 5α-reductase enzyme, with ergostadienol showing particularly high affinity and stability in in silico simulations.

This study reports a new industrial process for making finasteride using novel protective groups, demonstrated through spectral data of newly prepared compounds.

In this study, BECD-treated wavy hair showed reduced undulation and improved straightening after drying, as BECD enhanced the contraction and rearrangement of molecular chains in non-keratin proteins, unlike untreated hair, which retained its wavy structure.

This study developed and validated a sensitive liquid chromatography–mass spectrometry method to measure aristolochic acid‐I in rat plasma, successfully applying it to pharmacokinetic research.

This study found that ethanol-induced deficits in motor coordination in rats are not mediated by elevated neuroactive steroid biosynthesis.

This study found that xylanase and pectinase enzymes clean wool and specialty hair fibers as effectively as soap, without causing physical damage, whereas resinase was not effective.

In this study, researchers introduced a visible-light-mediated intramolecular cycloaddition method that selectively forms 6-azabicyclo[3.1.1]heptanes, suggesting these structures could offer promising new scaffolds for drug discovery and medicinal chemistry.

This study observed that bleaching brown human hair with persulfate salts and hydrogen peroxide induced significant conformational changes in keratin, particularly affecting disulfide bridges and oxidized sulfur species, which may inform the development of hair restorative treatments.

This study found that some synthesized 17-oximino-5-androsten-3β-yl esters demonstrated stronger cytotoxicity and antiandrogenic activity against prostate cancer cells than finasteride.

This study found that using 1,4-butylenediamine bismaleimide for hair perming through thiol-Michael click chemistry offers comparable efficiency to conventional oxidative methods, with enhanced durability and reduced damage to hair fibres, preserving mechanical, color, and surface properties.

This study found that compound 10 inhibited testosterone conversion to DHT in hamster flank organs and seminal vesicles, whereas compound 11's inhibitory effect varied with dose, linked to halogen electronegativity differences.

This study discusses ethosomes, which are lipid-based vesicular carriers that improve drug penetration into the skin due to their high ethanol content, highlighting their benefits in drug delivery despite stability issues like phospholipid oxidation and vesicle fusion during storage.

This study found that 42% of red yeast rice dietary supplements did not list monacolin concentrations on their labels, and only half of those that did contained the declared amounts.
