When it comes to over-the-door hooks, there is some debate as to whether or not they can damage your door. While most hooks are designed to be used on doors without causing any damage, some users have reported that their hooks have caused dents or scratches in their door. If you're concerned about damaging your door, you may want to avoid using an over-the-door hook. However, if you do use one, be sure to follow the manufacturer's instructions carefully to ensure that it is installed correctly and won't damage your door.
