Well you have to wear some sort of jewelry after getting daith piercings or it will close, and sadly, since daith piercings go through mostly cartilage, they take a lot longer to heal. You could actually try wearing clear daith jewelry made from a surgical plastic. It is flexible, but won't let the hole close and is also lighter then regular daith jewelry.

hmmm never thought of that, will try some in the holes I have now and see how I react. Thanks
