This review explores research on nanoformulations for enhancing the topical delivery of herbal medicines, noting potential benefits like improved bioavailability and sustained delivery, and emphasizes the need for safety and toxicity guidelines in developing these novel drug delivery systems.

In this study, researchers reviewed literature on topical delivery of finasteride for androgenetic alopecia, finding that liposomal gels with specific additives showed the highest skin permeation rates, suggesting potential for reducing systemic side effects compared to oral formulations.

This research explores developing liposomal formulations to enhance the delivery of difficult-to-absorb agents directly to hair follicles and sebaceous glands, with minoxidil and plasmid DNA as study molecules.

In this review, researchers examined the molecular pharmacology and effects of topical minoxidil, noting its potential to treat androgenetic alopecia by enhancing hair regrowth, while also discussing advanced formulation methods like nanoemulsion and nanocarrier systems to improve its delivery.

This study found that finasteride-loaded liposomal formulations achieved significantly higher skin permeation and deposition compared to conventional gels and solutions, suggesting potential for effective topical application.
