It sounds like Alopecia, which doesn't typically respond to meds. Did the doctor check his thyroid? I hate that "stress causes hair loss" statement coming from doctors. It just sounds like a scapegoat to me. If you can, find some girls to tell him how hot he is. That meant a lot to my brother. He was good looking with great hair, smart, talented, and popular. But losing his hair at 13 was a huge blow to his self esteem. For a time he couldn't see the value in any of those other qualities. And having his mom and sister compliment him and remind him that there are many sexy bald famous men in the world was not quite enough. He needed girls to still want him. One day my mom secretly called one of his female friends and asked her to help in this and she got several girls together to call him and give him encouragement. He suspected Mom had something to do with it, but it still meant a lot to him and he perked up. Another thing that meant a lot to him was when his football team shaved their heads in his honor.
