The best age and time to get treatment is as soon as you start noticing the signs of genetic alopecia. Contrary to popular belief, genetic alopecia can affect any person between the ages of 12 to 40. Men and women see different patterns of baldness but the very first common sign is excessive hair loss. 1 in every 50 person suffers from genetic alopecia at some point of his or her life. Early intervention can save you with the devastating psychosocial impact of premature balding.
