A navel piercing is a surface piercing of a sorts. So it has more of a chance to migrate. The hood is an actual piece of skin protruding from the body so there should be less of a chance of it migrating. However some people are more genetically prone to rejecting foreign objects from there body. A thinner gauge would actually in most cases make it easier to migrate. Is there anything else I can help you with?
