I am a 28 yr old active male in is great physical condition. Recently I have been noticing bald spots appearing on my neck where hair use to grow. Then spots where the hair use to grow are completely bald now. I am trying to find out what may be the cause of this.

This could be some peculiar genetic trait, or something like Ringworm (a fungus infection). You also might have alopecia areata. Alopecia areata can cause circular patches of baldness and could be seen almost anywhere in body, including scalp, beard, eyebrow and even eyelashes. The outcome is usually good and in most cases hair re-grows within several months. Occasionally the baldness could be permanent. Alopecia areata is an autoimmune disease and typically recovers in most cases without any treatments.

There are far too many possibilities, so you should see a dermatologist and get an opinion as well as a thorough examination of your body and scalp hair. Let an expert give you an opinion after an examination, something I simply can not do over the internet.
