Bio-Fen Plus for Women® provides a natural, safer alternative to expensive drugs, and/or expensive and painful hair transplants. Specific compounds within Bio-Fen Plus for Women® herbal extracts inhibit the 5AR enzyme (which reduces DHT) to prevent or slow down the rate of hair loss, this process is the principle by which the prescription drug Propecia (finasteride) works. Unlike Propecia, Bio-Fen Plus for Women® contains additional natural compounds that reduce excess cholesterol (so that less DHT can be produced) and vitamins to increase blood flow to the small capillaries that feed the hair roots. It contains silicon, which has been shown to contribute to hair shaft strength and thus healthy hair growth. It also contains iron – a number of studies have related sub-clinical iron deficiency in women to diffuse hair loss/alopecia. As with the prescription alternatives, results vary from person to person, and no one product will work for everyone.
