An American Herb company was recently issued a patent for the use of soy extract for the treatment and prevention of hair loss. Following are excerpts from the patent itself.
"The present invention is based on the principle that plants and plant extracts containing isoflavones can inhibit hair loss. Plants or plant extracts containing isoflavones can be administered either orally or topically to prevent hair loss.
The present invention provides the additional benefit that the administration of isoflavone-containing plants or plant extracts can provide other health benefits in addition to preventing hair loss. Another advantage of the invention is that the isoflavone-containing plants and plant extracts can be combined with other pharmaceutical treatments for preventing hair loss without adversely affecting the beneficial and positive effects of such treatments.""It is a further object of the invention to provide a method of preventing hair loss which may be used orally."
"The present invention is based on the principle that plants or plant extracts containing isoflavones may be administered orally or topically to prevent hair loss."
"The isoflavones of the present invention include those which exhibit
estrogenic activity and which bind to testosterone receptors. Such
isoflavones prevent the "hair loss" effect of testosterone by inhibiting
the binding of testosterone to the hair and scalp receptor, thereby
resulting in maintenance of scalp hair integrity."
