This review discusses various patent articles on microemulsion carriers in drug delivery systems and reports no new empirical findings.

Polyquaternium 7® builds up on hair, improving its look and feel, and AFM is good for measuring these changes.

This study developed and validated a micellar electrokinetic chromatography method to determine finasteride stability, finding that the drug degrades under acidic, basic, and oxidative stress conditions.

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 demonstrated that a nanoemulsion hair tonic containing 7% candlenut oil accelerated hair growth more effectively in Mus musculus than both lower concentrations and a commercial ginseng tonic.

This study found considerable variation in hair shaft proteomic profiles among Caucasian, African-American, Kenyan, and Korean subjects, with individual and site-specific differences observed.

This study used proteomic profiling to reveal significant individual and site-specific differences in human hair shaft proteins, which may improve the differentiation of hair based on ethnic origin and individual identity.

This research concluded that the novel hydrogel PlacMA, derived from human placenta and curable by visible light, shows promise for cell culture and tissue engineering applications due to its tunable properties.

This review discusses the role of keratins in epithelial cell stress protection and cancer, highlighting their potential as multifunctional regulators and diagnostic markers, without presenting new research findings.

This study found that specific human hair keratins are differentially expressed in the hair follicle, suggesting a shared pathway of epithelial differentiation between hair cortex and nail plate cells.

This study identifies mutations in the SRD5A3 gene as a cause of a new type of congenital disorder of glycosylation, impacting mental, ophthalmologic, and cerebellar functions.

This study provides evidence that human skin contains genes and enzymes necessary for producing serotonin and melatonin.

This review discusses recent advances in skin penetration mechanisms, specifically focusing on the enhanced understanding of the follicular pathway and its implications for transdermal therapies, immune system targeting, and nanoparticle safety.

This review discusses the potential of lecithin organogels for improving topical drug delivery and presents no new experimental results; the authors highlight their stability and low skin irritancy as advantages.

This study found that chitosan nanofibrillar scaffolds accelerated skin wound healing in mice by enhancing cell adhesion, proliferation, and regeneration of epidermis and dermis compared to other forms.

This study found that adding microneedling to minoxidil treatment significantly improved hair growth in men with androgenetic alopecia compared to minoxidil alone across all assessed measures.

This review discusses various nanoparticles used to enhance skin permeation and target delivery to skin organelles, but reports no new experimental results.

Minoxidil can help grow hair in mice by making cells grow and improving hair quality. More research needed.

This study identified a distinct "exogen" phase in the hair cycle during which hair shedding occurs, primarily coupled with the anagen phase, rather than as part of the telogen phase.

This study found that carbon nanotube impurities induced immunological toxicity in mice, whereas purified nanotubes showed good biocompatibility, suggesting high-temperature thermal treatment may improve nanotube biocompatibility.

This review reports on the dual aspect of fullerene in skincare, highlighting its beneficial antioxidant properties as well as potential toxicity and skin cell reactions, while identifying areas for future research.

This study suggests that spironolactone-loaded nanostructured lipid carriers could enhance follicular delivery and offer a more localized treatment for androgenic alopecia, potentially reducing systemic side effects.

Ethosomes improve finasteride delivery through skin for hair loss treatment.

This study found that baicalin delivery through polymeric nanocapsules significantly enhanced its anticancer activity in breast cancer cell lines MCF-7 and MDA-MB-231.

This review discusses the properties and therapeutic potentials of beta-sitosterol, highlighting a need for more detailed studies on its mechanisms and long-term effects in humans; it reports no new results.

This review discusses the use of dermal regeneration templates for treating burn injuries and other wounds, highlighting their effectiveness in reducing scars and aiding in regenerative processes, but reports no new clinical results.

This study found that the binding of finasteride to the enzyme 5a-reductase occurs at a slower rate than previously assumed, complicating the estimation of its real inhibitory constant.

This study reviews recent advancements in microneedles made from PLGA, highlighting their use in delivering vaccines, drugs, and proteins through the skin with minimal invasiveness, and discusses the challenges and future potential of these delivery systems.

This review examines the main absorption sites and influencing factors for orally administered drugs, highlighting variables such as solubility and gastrointestinal conditions that affect drug absorption in the small intestine and the development of effective drug delivery systems.
