Hi, My brother is 23 year old and has circular patch in beard on right side. He has dense dark beard and doesn't have any patch in other areas. We consulted a dermatologist and he said he has Alopecia Areata Barbae. He told that the only solution is hair transplant and there is no other diagnosis. He also told that doctors will prescribe you Cortisone and minoxidil which have show results rarely and have more side effects. I am scared and totally confused what to do
