👉 Nailhead is a type of nail that appears on the outer layer of nails, typically in the first and second digits. They are often found as small bumps or thin areas where the nail is split from the base of the nail. These nips can appear anywhere on the nail, but they usually form at the base of the nail when it is cut or tapped. Nailheads may also be called "nail pits" or "nail scrapes".
