This study found that photodynamic therapy using 5-aminolevulinic acid or methyl aminolevulinate is a safe and effective treatment for acne vulgaris, particularly with 30 to 60 minutes of contact time and three treatments for significant long-term improvement.

In this study, cell membrane remodeling with a thermoresponsive boronic acid copolymer was shown to rapidly form spheroids from cancer or cardiac cell lines under standard conditions, promising advances in tissue engineering.

This study found that local androgen biosynthesis and metabolism in human sebaceous glands play a crucial role in sebum synthesis and secretion.

This review discusses recent advancements in cutaneous drug delivery technologies and the potential of transfollicular pathways for improved treatment of skin conditions, but reports no clinical results.

This review discusses ethosomes as lipid carriers that enhance drug penetration into deep skin layers and underscores the need for advanced research on their pharmaceutical applications, but it reports no clinical outcomes.

This review examines the benefits and potential risks of androgen replacement therapy for male hypogonadism but reports no new clinical results; the authors highlight the need for careful risk assessment, especially in older men.

This study found that C57BL/6 mice with a diet containing specific levels of vitamin A showed alterations in retinoid metabolism and increased frequency of cicatricial alopecias, suggesting dietary factors may play a role in this condition.

In this study, extracting internal lipids from Caucasian hair fibers led to decreased water permeability, influenced by the fluidity of lipids.

In this mouse study, hair growth defects associated with the Gk5 null allele were partially alleviated by simvastatin treatment, suggesting GK5 plays a key role in skin-specific cholesterol regulation.

This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.

This review discusses the pathogenesis of common sebaceous gland diseases and their molecular pathways, but it reports no new clinical findings.

This study suggests that DHT may have a less potent effect on the prostate compared to testosterone while maintaining safety and similar effects on erythropoiesis and lipids.

This research article evaluates the protein content of yeast grown on wood hydrolyzate, without providing new results or clinical findings.

This study found that in Japanese, German, and American females, changes in hair lipid patterns with age may reflect alterations in sebum excretion and affect hair texture.

This study reports that 4-(alkylthio)- and 4-(arylthio)-benzonitriles showed moderate sebum reduction as androgen receptor antagonists when applied topically in a validated animal model.

This study found that bisindolylmaleimide PKC inhibitors increased DNA synthesis in mouse hair follicles, suggesting that PKC may inhibit hair follicle proliferation.

This study found that variations in sleep patterns, free testosterone, and 5-alpha-reductase type 1 activity are associated with changes in sebum excretion in women, which may contribute to variability in acne studies.

This study found that hair follicle-plugging reduced skin permeation of certain model drugs, with effects varying based on EtOH pretreatment and the drug being evaluated.

In this study, NREs from lentil root nodules, specifically Serratia plymuthica 33GS and Serratia sp. R6, significantly enhanced lentil growth, altered root exudation, and modulated rhizospheric microbial communities in a greenhouse setting.

This study found that extract of Hura crepitans inhibited androgen-accelerated NT-4 activity and ameliorated the retardation of hair regrowth in dihydrotestosterone-implanted mice, suggesting a potential role for NT-4 inhibitors in AGA.

This study observed that Biota orientalis L. leaf extract may promote hair growth and suppress sebum production in human cells, suggesting potential benefits for hair restoration.

In this study, researchers found that sweet potato shochu oil promotes hair growth in both human follicle dermal papilla cells and C3H mice. The oil contains components like ethyl palmitate, ethyl linoleate, and ethyl α-linolenate, which were key contributors to its hair growth-inducing effects.

Finasteride safely treats enlarged prostate and male-pattern baldness.

This study reported that squarticles, nanoparticle carriers made from sebum-derived lipids, significantly enhanced minoxidil delivery to hair follicles in vitro, increasing follicular uptake sevenfold and minimizing systemic absorption compared to a free control solution, while showing good skin tolerability.

The document concludes that sex hormones are crucial for mammalian reproduction, health, and behavior, and require more research for therapeutic use.

This study observed that DDAIP-HCl enhanced the permeation of minoxidil through human cadaver skin, suggesting potential for improved treatment efficacy in male pattern hair loss.

This review examines glycopeptide hydrogels as biomimetic materials for tissue regeneration and other biomedical applications, describing their design, properties, and potential uses, and highlighting future advancements in replicating natural tissue environments for precision medicine.

This chapter reviews the hair follicle's role in drug and chemical penetration through the skin but does not present new experimental findings.

This chapter reviews the chemistry and potential benefits of plant-based hair dyes in cosmetics, but it reports no new clinical results.

This study analyzed the lipid composition of mouse hair, focusing on sphingolipids, and found significant differences in ceramides, glucosylceramides, and sphingomyelins between hair follicles and hair shafts.
