Like sunshine, which can burn if you get too much, there is such a thing as TOO much 
testosterone (or any other of the female hormones). While too little can cause or exacerbate a whole host of health conditions, excess levels can lead to masculinization, including deepening of the voice, abnormal hair growth, acne, and even hair loss.
The areas that tend to be the most affected by excess hair growth are in those areas that have the greatest concentrations of androgens such as testosterone. These include the chin, upper lip, cheeks, just below the navel, and around the nipple. For similar reasons, women with the opposite end of the spectrum (hair loss) will notice the greatest decrease in hair on the top of their head, at the crown, or at the temples.
If you are exhibiting any of these symptoms, work with your doctor to evaluate your hormones, including your testosterone levels.
