Facial hair in women is related to hormone imbalances. It occurs most commonly when there are high levels of a hormone called Dihydrotestosterone (DHT). Testosterone is converted into DHT and under certain circumstances, such as Insulin resistance, this conversion happens at an increased rate, leading to elevated levels of DHT. There are several supplements which can help to block the conversion of Testosterone into DHT, but it is important to also look at the underlying cause. If the underlying cause is left untreated simple supplementation will not be effective. I would recommend that you make an appointment with a Health Renewal doctor so that all possible underlying causes may be evaluated properly. Elevated levels of DHT are also linked to Acne and polycystic ovaries and needs to be treated.
