Saw Palmetto If you want the main ingredient that's in 90% of the natural hair loss treatments out there then get Saw Palmetto. Saw Palmetto has become a popular hair loss supplement because of it's reputation for promoting prostate health by reducing DHT. Since prostatic disease and hair loss are connected in several different ways many herbalist have begun marketing Saw Palmetto as a hair loss treatment. Propecia (Finasteride) was originally marketed as a prostatic treatment as well. It became a hair loss treatment after patients started noticing changes in hair growth. Saw Palmetto, like Propecia, will help you lower the amount of DHT produced in the body. However, it's debatable whether or not it will work quite as well as Propecia. You should also know that Saw Palmetto does have side effects and drug interactions. Pregnant women should avoid Saw Palmetto because it could be dangerous to unborn babies. It might not have any hair growth benefits for women at all. In a few cases Saw Palmetto has caused hemorrhages, difficulty urinating, swelling of the prostate, and blood in the urine. 2. Nettle Root Nettle Root is a another supplement that's often put into natural hair loss treatments. It helps block 5-Alpha-Reductase which causes testosterone to be converted to DHT. This supplement is often included in the top tier natural hair loss treatments. Nettle root is considered a stronger DHT blocker than Saw Palmetto by some herbalist. In most cases natural hair loss treatments don't have any nettle root in them at all. The ones that do have nettle root often don't have enough. However, like saw palmetto nettle root does have some negative interactions with prescription drugs. Be careful if you are taking blood pressure medication, diabetes medicine or sedatives. Unlike, Saw Palmetto women with hair loss can use it as well. 3. Dong Quai Dong Quai is another DHT blocker. It has phytoestrogens which block androgen-receptor sites that help convert testosterone to DHT. Since it works to block DHT many people believe that it will also help prevent hair loss. Dong Quai can also be used by women. If you combine Dong Quai with Nettle Root then you will probably have a regimen that's stronger than most natural hair loss treatments on the market. Combine all three and you will have the best possible supplement regimen at a much more affordable price.
