Independent Studies in Japan have said to have found concrete evidence that apple polyphenols are 300% more effective than minoxidil when concentrated.
Just eating apples has also shown to slow down DHT.
This is somewhat old news but I hear very little about it. Probably since some big corporation couldn't profit off it.
However, I don't see the hurt in eating a apple a day. Since Apples are known as a miracle fruit. In fact the whole genome of the apple holds alot of beneficial properties we have yet to discover. Eating a apple a day to fight hair loss and Improve your health is a positive. Its a cheap investment and either way beneficial to you.
