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.
Dutasteride has a larger volume of distribution than finasteride due to its lipophilic nature, allowing it to concentrate in hydrophobic areas and making it difficult to excrete. A user experiencing hair loss has been using oral finasteride for 10 months with minimal regrowth and is considering switching to dutasteride or adding oral minoxidil.
Topical finasteride that doesn't penetrate the skin could potentially treat hair loss without side effects. Current challenges include finding a formulation that remains on the scalp without increasing blood levels.
How Pyrilutamide, a hair loss treatment, has improved texture and regrowth of hair without any side effects for users, who are encouraged to post progress photos.
The user stopped finasteride due to testicular aches and switched to minoxidil, seeing positive results in three months. They are considering topical finasteride but are cautious because of past side effects from oral use.
