I remember when i first met you BM your hairline had a tiny bit missing like that until you had it sorted....i agree with Jessop too the hairstyle does not do him any favours in disguising his loss at all. I wonder if he is on meds now he has started to loose his hair a little?
His temple points look strong though so if Meds stabalised his loss i think a small procedure would sort him out. But then again he may just be accepting his loss and it might not even bother him.
