You can add a humid hide with sphagnum moss in it. Kind of weird your BP is having problems shedding with 50-55% humidity. I run around 50-60% and mine sheds fine all in 1 piece. Is this his first shed? Mine had a piece stuck to her head on her first shed with me but since then, she has shed 2 more times and both times were in 1 piece perfect. But like I said, try a humid hide and with 50-55% humidity normally, if he has a bad shed with that, then you might have other issues.
