Alopecia Areata: Check to see if there is an underlying condition like alopecia areata or a fungal infection in the area. A dermatologist should be able to help- bloodwork & a biopsy may be necessary.

Normal: In all likelihood, this is just a normal variation. In time even the currently hairless skin may develop hair. To maintain good health: Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco or alcohol in any form.
