Criss Angel is lending a helping hand to his 5-year-old son Johnny while he fights cancer.

On Wednesday, the magician, 52, shared a video on Instagram in which he buzzes off Johnny's hair.

"Do you want to keep your hair long and we'll just let it fall out?" Angel asks his son in the video. "Or do you want me to cut it off? It's up to you."

Evidently, Johnny chose to cut his hair, as Angel could then be seen taking sheers and a razor to his son's dark locks.
