There are different reasons for hair loss. However, male pattern baldness is caused by DHT (DiHydroTestosterone). When DHT is attached to hair follicles it causes the follicles to shrink and eventually they die.

DHT is produced when the enzyme 5 alpha reductase interacts with testosterone. So to stop losing hair, you need to block DHT.

Popular drug Propecia is a DHT blocker. It lowers the levels of DHT in the body by blocking the enzyme 5 alpha reductase. But it has some side effects.

Fortunately, there are some good natural DHT blockers. Green tea is one the best natural DHT inhibitors. Green tea is s a very powerful anti-oxidant. You can drink the tea or take a pill extract to stop hair loss.

Saw Palmetto (a palm plant native to North America) is another herbal DHT inhibitor. It has similar mechanism of action to finasteride, but without side effects associated with this prescription drug.

You can take Saw Palmetto on its own without the use of a topical treatment. However, this is not the best way to go. You should use a Saw Palmetto treatment that is both oral and topical.

Pumpkin is not just for Halloween! Apply a large quantity of pumpkin seed oil to your scalp before going to bed. Do this everyday for 6 months and you will limit DHT production.

P.S. Zinc is one of the best natural mineral DHT blockers available in nature.
