Dihydrotestosterone and the Concept of 5-Alpha-Reductase Inhibition in Human Benign Prostatic Hyperplasia

Finasteride is the most effective treatment for reducing DHT and addressing hair loss compared to fish oil and saw palmetto. Topical treatments like RU58841 and minoxidil are also discussed, but finasteride remains the most effective option.

The conversation discusses using finasteride, dutasteride, RU58841, and testosterone to combat hair loss and block DHT, with some users expressing concerns about side effects and vegan options for medication. The discussion also touches on personal experiences with hormone treatments and the desire to maintain a youthful appearance.

GT20029 shows promise as a topical treatment for hair loss, potentially replacing finasteride for some due to its low systemic exposure and ability to degrade androgen receptors. However, skepticism remains about its long-term efficacy and availability, with some users expressing doubt about new treatments consistently failing to reach the market.

Natural vitamins like pumpkin seed oil, saw palmetto, and ecklonia cava are discussed for their potential to lower DHT levels. They may work similarly to finasteride but are significantly weaker.

Topical androgen receptor antagonists may not be necessary if 5-AR inhibitors like finasteride or dutasteride effectively reduce DHT levels. Combining a 5-AR inhibitor with a topical androgen antagonist could potentially enhance treatment, but oral use of androgen antagonists is too risky due to severe side effects.

A 19-year-old used a 0.01% topical finasteride formula, which unexpectedly lowered DHT levels significantly. They are considering reducing the dose further and exploring alternatives like ketoconazole shampoo, KX826, and CB to manage hair loss while minimizing systemic absorption.
