So-called "thinning hair supplements," "hair farming products" and "vasodilators" for the scalp will not promote hair growth, says Mike Mahoney, a spokesperson for the American Hair Loss Council.
Thinning hair supplements are nothing more than hair conditioners that temporarily make your hair feel or look a little thicker. The main ingredient in these products--polysorbate--is also found in many shampoos. Promotional materials for hair farming products claim that they will release hairs that are "trapped" in a bald scalp. Mahoney says these products, many of which are herbal preparations, can do no such thing. And so-called vasodilators do not increase the blood supply to the scalp and do not promote hair growth.
