The distal part â that's the separation between the white and pink part â has a curved shape. That's creating the stresses, Rauch told Live Science. Eventually, this stress causes the far edge of the nail to poke down into the skin alongside the nail, leading to an ingrown nail, the researchers found. Themedical name for the condition is onychocryptosis. These forces are also the reason that the big toe seems especially prone to ingrown nails, Rauch said.
