Can Herbal Supplements prevent hair loss? 
Supplements are not regulated by the Food and Drug Administration (FDA). Any statements made by a Supplement manufacturer are required to have the disclaimer “these statements have not been evaluated by the FDA”.
There is a legal differentiation between “statement” and “claim”. Making a claim such as “this herbal oil will regrow your natural hair”, requires absolute proof and the manufacturer can be sued for making a false claim. “Many men have seen visible results with our miracle herbal hair
oil”, sounds the same but is simply a statement and not a claim even though to the untrained ear it sounds the same. The effect however is the same in advertising terms because it is an exhortation to try the “miracle oil”, since many men allegedly have seen visible results.
Every time you see (in the fine print) that these statements have not been evaluated by the FDA, you can be pretty sure you are dealling with a statement and is actually a “buyer beware” sign. So, Can Herbal Supplements prevent hair loss? Look for the signs on the label.
