Development and Characterization of Hydrogel Containing Finasteride

Switching from propylene glycol to glycerin in topical finasteride may reduce systemic absorption and side effects while maintaining local scalp DHT suppression. Concerns exist about glycerin's ability to deliver the full dose to hair follicles.

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.

The conversation discusses the best ethanol and propylene glycol ratio for homemade topical finasteride, with a focus on absorption and drying issues. The user shares their experience using a 50% propylene glycol, 30% ethanol, and 20% water solution, and considers adjusting the ethanol content for better results.

Users discuss making topical finasteride solutions by dissolving crushed tablets in ethanol and propylene glycol, with concerns about residue affecting effectiveness. They also mention using minoxidil and oral finasteride, noting some hair regrowth and no side effects from topical use.

The conversation discusses using Rogain foam as a solvent for topical finasteride due to an allergy to propylene glycol. The foam's ingredients, including alcohol SD 40B, are considered suitable for dissolving finasteride for easier application without skin irritation.

The conversation discusses the pros and cons of using propylene glycol versus ethyl alcohol in topical solutions for finasteride and minoxidil. It questions why propylene glycol is commonly used and whether ethyl alcohol might be a better option.
