Health food stores and vitamin shops are packed to the rafters with products promising to prevent hair loss. Of course, since the main objective for many vitamin manufacturers is to find the easiest way to separate you from your money, you have to be able to separate fact from fiction when it comes to finding the right supplement to prevent hair loss.
For starters, avoid products that make outrageous claims. Hair loss is a complex matter and cannot be completely treated by swallowing a handful of capsules or pills. There is no miracle product that will regrow a full head of hair, and even if such a miracle product did exist it probably wouldn't be sold over-the-counter. However, there are several vitamins and nutritional supplements which have been proven to combat hair loss. While these supplements won't magically regrow hair, they have been proven to slow down the effects of hair loss.
