Hair growth products are everywhere, but unfortunately the majority of them ineffective at best. Even real FDA approved medications don't work on all people, have side effects, and won't make your hair grow faster. There is good news though. Medications like Rogaine and Propecia can help to prevent hair loss, and may even help some hair to grow back where you've already lost it. Additionally, certain vitamins are necessary for hair growth and if you're not getting enough of them in your diet than supplements can help.
If you're seriously concerned about your hair loss, see our sections on hair loss causes, prevention, and treatment. The only guaranteed way to grow your hair back is through surgery, which is a serious step you should discuss with your physician.
You should be very careful about using miraculous hair growth products you find on the internet or advertised in magazines. If it sounds too good to be true, it is. There are rumors about Chinese potions and Aryuvedic medicine that can grow hair fast, but you should consider that if there really was a potion guaranteed to grow hair fast, it would be all over the news and the makers would be wealthy. Everyone would be using it. Some of these potions are actually dangerous, as they claim to block estrogen, increase testosterone, or have toxic ingredients. At best, many of these fraudulent products will be a waste of your hard earned money.
One exception to all the fraudulent "natural products" for hair growth is saw palmetto. Saw palmetto was used by Native Americans to treat urinary symptoms, and similar to Propecia it has been shown to block the enzyme that converts testosterone to DHT, the hormone that causes male pattern baldness. It's widely used in Europe as a treatment for benign prostate gland enlargement, and works well to prevent further hair loss and potentially regrow hair in recently balding areas of the scalp. Saw palmetto can be taken orally or externally applied to the scalp. As with Propecia you should be careful only to apply saw palmetto to the area of your scalp you want hair to grown to avoid an increase in unwanted facial hair.
