I'm trying to get my users to post only once on each Product node... I'm kind of new to hooks and I'm not sure what else should I use for this.

What is the drupal way to do this?

You can use the Comment limit module.

Limits how many comments a user may post on a node. Adjustable on a per node type basis.

This module can be handy for instance when comments are used as "Reviews" and "Ratings" for products and a user may only review and rate a product once.
