This study found that nanoemulsion formulations with oleic acid or eucalyptol significantly enhanced the delivery and retention of caffeine through hair follicles and surrounding skin regions.

In this study, researchers developed a new self-administered finasteride delivery system using powder-carrying microneedles that improved hair growth efficacy and addressed safety concerns compared to topical finasteride gel by allowing sustained intradermal release of the drug for three days with a single application.

This review explores the use of skin penetration enhancers like Transcutol® in various formulation systems, discussing their mechanisms and effectiveness in improving transdermal drug delivery without breaching the skin.

This study reported that nanoemulsions significantly improved the skin permeability of thiocolchicoside compared to its aqueous solution, suggesting they are effective carriers for its transdermal delivery.

This pilot study found that a multimodal minoxidil microemulsion with diclofenac and tea tree oil was more effective and safer than minoxidil alone for treating androgenic alopecia over 32 weeks.

This study found that a lacticin 3147 solid lipid nanoparticle gel demonstrated potent and sustained antimicrobial activity against S. aureus, including MRSA, in ex vivo S. aureus-infected pig skin.

This study found that nano-sized minoxidil formulations significantly increased skin penetration and follicular drug delivery for alopecia areata treatment, compared to conventional ethanol-based solutions, and demonstrated effective controlled release over six hours.

Niosomes are a promising and effective way to deliver drugs through the skin.

In this study involving a mouse model, researchers reported that intranasal delivery of protein-based CRISPR/dCas9 nanoparticles targeting the gene *Sirt1* reduced cerebral edema and increased survival following ischemic stroke, with no significant toxicity observed.

This article discusses the benefits of liposomes in cosmetic formulations, including enhanced hydration and protection for dry skin, but reports no new experimental findings.

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

This review highlights the potential of nanoemulgel as a promising drug delivery system for lipophilic drugs, but presents no new experimental results; it discusses composition, preparation methods, and applications.

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 review highlights that nanoemulsions, especially those with droplet sizes under 200 nm, show promise in pharmaceuticals and cosmetics by improving drug stability, bioavailability, and reducing side effects, with potential applications in CNS diseases, cancer treatments, and skincare products.

This study concluded that fenugreek seed extract loaded solid lipid nanoparticles demonstrated enhanced skin retention and extended release, suggesting potential as a future alternative treatment for alopecia.

In this study, researchers found that topical ketoconazole showed delayed hair growth compared to minoxidil in female pattern hair loss but had fewer side effects, though patient satisfaction was similar for both treatments.

This study investigated spanlastic nanovascular drug delivery systems and found that they can effectively enhance the transport and continuous release of medicines with small particle size, low polydispersity index, and satisfactory entrapment efficiency, showing potential as carriers for drug delivery.

This study found that varying the concentration of propylene glycol in rice water shampoo gel affects physical properties such as viscosity and foam height, without impacting organoleptic qualities or pH stability.

This study found that various reduced folates effectively penetrated an in vitro skin model, promoted cell proliferation and migration, and may enhance wound healing, suggesting potential for topical treatment in skin conditions.

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 review found that anti-aging peptides show promise in cosmeceuticals due to their targeted actions to rejuvenate skin, but challenges like peptide stability, penetration, and limited clinical data limit their current effectiveness.

The researchers in this study conducted a comparative analysis of hair and body shampoos, finding notable physicochemical differences, such as body shampoos having lower surface tension and higher foam heights, while hair shampoos were more acidic, potentially to meet different biological and sensory needs.

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 developed a topical dutasteride-loaded Insitu-emulgel for treating androgenetic alopecia, finding it effectively controls drug release, enhances skin penetration, and may improve patient compliance compared to traditional topical treatments, though further clinical research is underway.

This source reviews the application of various natural substances, particularly plant extracts from the Ayurvedic system, in promoting hair growth, addressing common issues like pigmentation, dandruff, and hair loss.

This study found that a nanoemulsion containing perfluorooctyl bromide effectively increased oxygen levels in an anoxic environment, enhancing hair dermal papilla cell growth and significantly promoting hair organ elongation.

This research highlights the potential of emulgel as an advanced topical drug delivery system, offering improved efficacy for hydrophobic medications in treating dermatological conditions and a range of ailments with its dual release control mechanism of gel and emulsion.

This review discusses alopecia, its pathophysiology, nanotechnology-based drug delivery systems, and related quality of life issues, without reporting new clinical results.

In this in-vitro study, researchers found that shampoo-induced coacervates structurally resemble cationic polymers and contain anionic surfactants that may stimulate the scalp upon exposure to water.

This study found that high concentrations of dimethyl sulfoxide are needed to cause significant swelling in hair fibers, though the swelling is reversible, unlike the effects on skin.
