Healthline explains that it is normal for women to grow light hair on the face, which is often referred to as "peach fuzz." Excessive facial hair growth is referred to as hirsutism. The hair growth patterns of hirsutism in women are similar to male hair growth, and the hair's texture is coarse. Causes for male hair growth patterns in women include steroid or testosterone injections, adrenal cancer and Cushing's disease. Cushing's disease is a condition in which the body produces excessive levels of cortisol, a male hormone that is often referred to as the "stress hormone."
