Effect of Finasteride Particle Size Reduction on Its Pharmacokinetic, Tissue Distribution, and Cellular Permeation

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.

Topical finasteride results in plasma levels 100 times lower than oral finasteride, potentially reducing systemic side effects. Users report similar efficacy with fewer side effects, suggesting a preference for topical application.

Taking Propecia (finasteride) with olive oil is unnecessary because it is water-soluble and already has high bioavailability. Dutasteride tablets should be taken with something fatty like olive oil to improve absorption.

Topical finasteride concentrations are likely much higher than necessary for effective follicular DHT suppression, with current standards being 100-1000 times above the theoretical minimum. Lower concentrations (0.001-0.0025%) might still work locally while minimizing systemic exposure.

Topical finasteride is believed to reduce scalp DHT more than oral forms, but its effectiveness is questioned due to inconsistent application and absorption. Oral finasteride is considered more effective because it consistently reduces systemic DHT, ensuring more reliable results.

Topical finasteride (P-3074) can inhibit scalp DHT by up to 70%, with some users experiencing systemic absorption similar to oral use. Users discuss varying application frequencies and concentrations, with some noticing side effects when overused.
