Daith

The daith goes through the crus of the helix — the small fold of cartilage that curls into the ear just above the canal. It is a tight, awkward angle to reach, which is why it takes a skilled piercer and the right tools.

That fold is also why a daith takes a ring and not a stud. A straight post has nowhere to sit flush; it will press against the fold on one side and stand proud on the other. A hinged clicker is the sensible first piece, because it opens and closes by hand without tools near a healing piercing.

You will read that a daith helps migraines. There is no good evidence for it. Get one because you like how it looks.

Tucked inside the ear, so it is better protected than most — but harder to rinse properly. Let saline run through the fold rather than dabbing at the surface.

Do not attempt to change a seamless ring yourself. That is a tools job.
