I think your fiance has done what needs to be done. Now, he'll see a good reaction from all his associates in business & private life. No worry about hair, he'll notice people remember his name--you're sort of disposable with a case of mpb, but everyone, the clerk at the shirt laundry, the cashier at his favorite lunch spot, they'll all now remember his name. That's fun, and it happens.
You don't need to worry about him, except keeping the other girls' hands off that dome--they find it unresistable. So, rub it softly gently--it is one of the most sensual parts of a man's body as we have all found out.
Treat that dome right & you'll find a part of the man you never even knew existed.
