community What About Phytosterol Alternatives - Rice Bran Oil - Natural DHT Blockers

in Research/Science 3 upvotes 1 year ago

The conversation discusses natural DHT blockers like rice bran oil, which may reduce 5α-reductase activity similarly to Minoxidil and Dutasteride. One user argues that finasteride is more reliable and effective than natural alternatives.

community Tretinoin can make it worse!!!

in Chat 7 upvotes 2 years ago

Tretinoin may enhance minoxidil's effectiveness for those not responding to minoxidil alone, but it could reduce efficacy for some who are already responding to minoxidil. Tretinoin requires careful use, including skin moisturizing and sun protection due to increased sensitivity.
