Core-Shell Nanocarriers Based on PEGylated Hydrophobic Hyperbranched Polyesters

A peptide-based delivery system for finasteride shows promise in reducing systemic side effects while maintaining hair growth effectiveness. Combining this with other treatments like minoxidil and RU58841 could enhance results with lower systemic absorption.

The conversation discusses the potential benefits of creating a hydrophobic version of finasteride to reduce systemic side effects while maintaining scalp health. It compares this idea to fluridil, which is designed to be hydrophobic and has less systemic absorption.

Topical finasteride in a liposomal formulation reduces systemic absorption compared to ethanol solutions. The user is seeking sources for such products, noting that popular options like morr-f are not liposomal.

The conversation discusses a topical finasteride therapy with hydrocortisone butyrate, estrone base, and breviline. A user suggests oral finasteride as a superior option.

Topical finasteride may have higher systemic absorption and lower efficacy when using a Propylene Glycol/Ethanol formulation compared to the hydroxypropyl chitosan (HPCH) formulation. The safety profile of topical finasteride relies heavily on the HPCH formulation, and using standard solutions might lead to different pharmacokinetics.

The user is using a topical solution containing 1% finasteride and 5% minoxidil for hair loss, with water, glycerin, and PEG-40 hydrogenated castor oil as carrier agents. They are questioning if these ingredients are effective carriers after using the solution for three months.
