The verb "help" is part of a small class of verbs known as causative verbs.
These verbs are let, make, have (not for possession), and get.
The verbs let, make, and have (have as a causative) are not followed by "to". However, "get" is followed by "to".
The verb "help" is unique because it can be followed by "to" or not be followed by "to".
I believe I've observed that "help" is sometimes followed by "to" in a more formal style. I think this is so. For everyday conversation, I recommend not using "to" after "help".
