The disorder in which the nail grows into the edge of the nail grooves is called what?

The disorder in which the nail grows into the edge of the nail grooves is known as onychocryptosis, commonly referred to as an ingrown nail. This condition occurs when the edges of the nail, typically the toenail, curve downward and penetrate the surrounding skin, leading to pain, inflammation, and sometimes infection.

Understanding this condition is crucial for nail technicians since they may encounter clients with ingrown nails and will need to advise on appropriate care or refer to a healthcare professional. In contrast, onychorrhexis refers to brittle nails that split or break easily, onychatropia describes a condition where the nails shrink or become smaller, and leuconychia pertains to white spots on the nails, none of which involve the nail growing into the skin. Thus, knowing onychocryptosis and its distinct characteristics is important for proper diagnosis and treatment in nail care.
