You need to be evaluated by a good doctor that specializes in hair loss. Loss of hair from the sides and back is unusual in men and common in women. There are too many possibilities here to discuss and there is no substitute for a good doctor to evaluate you. You can contact a dermatologist that specializes in hair loss, or has an interest in this field. If I were to guess on your problem, I would have to make a list of possibilities and that may do more to confuse you than to help you.
