You can start fin now to help maintain your existing hair and protect your transplant investment. It blocks DHT, which is responsible for hair follicle miniaturization in AGA. Side effects like decreased libido are possible but uncommon. It can take several months to see results. Check out the Beginner’s Guide for more info.
