My daughter had the same problem her hair was very, very fine and blonde hair. I sprayed the part of her hair that was frizzy with Johnson and Johnson "No More Tangles" and combed it out. I would do this several times a day if I needed to and left the spray in her hair. I also would use a vial of serum (in the conditioner area of the store) on it once in a while to strengthen her hair. I think she wrapped her blanket around her head and that made it more frizzed. If he uses a pillow try a silky or satin pillow case or a silky/satin sheet for his bed.
