Yes, helium will help a balloon fly. Helium does not affect the direction that a balloon goes, but it will keep it in the air for quite some time.
The force of buoyancy, which is created by the displacement of air by the balloon, allows it to fly. This force is greater than the weight of the balloon, causing it to rise.
