Natural ways to block Dihydrotestosterone (DHT) are to increase the amounts of zinc, saw palmetto, Pygeum, and prolactin in the body, notes Natural Health Web. Natural DHT remedies are available without a prescription and are safer than prescription products, which can often interfere with testosterone levels in the body.
DHT is a byproduct of testosterone that attacks susceptible hair follicles and prevents hair growth. Since testosterone levels are generally higher in men than women, men are more likely to experience DHT-related hair loss. DHT is also a cause of other health issues such as prostate cancer, as stated on Natural Health Web.
