A 23-year-old achieved significant hairline regrowth using minoxidil, saw palmetto, collagen peptides, biotin, omega-3, iron, ketoconazole shampoo, and scalp care techniques, without finasteride or dutasteride. The user attributes success to this combination but is unsure which element is most effective.
Deoxyribose sugar gel may stimulate hair regrowth similarly to minoxidil by enhancing blood supply and follicle activity. Human trials are necessary, and current products have mixed results.
Finasteride can affect sperm quality, but fertility usually returns after stopping it, as shown by a user who conceived four months after discontinuation. Some users successfully conceive while on finasteride, though some prefer to pause its use to minimize risks.
RU58841 is used topically to prevent hair loss by blocking DHT, with suggestions to drink grapefruit juice, take breaks, avoid microneedling, and use lower concentrations to reduce side effects. Users discuss applying it at night to minimize systemic absorption.
Finasteride may cause elevated liver enzymes, potentially leading to liver issues, though this is rare. Users should monitor liver function and consider topical alternatives if liver sensitivity occurs.
