If your hair is thinning rather than balding, consider non-surgical hair restoration. In this sort of treatment, hair is bonded to existing hair to provide a fuller head of hair. This is not recommended, however, if your hair is falling out -- or you might loose your new extensions.
Don't expect any hair restoration technique to miraculously return you to the way you once were, not matter what the commercials say. Restoration techniques can offer you a better look and boost your self-confidence, however, and that may be all that matters.
