What condition is identified by an increased curvature of the nail?

Pincer nails are characterized by an increased curvature of the nail, which often creates a shape resembling a claw. This condition occurs when the sides of the nail plate involute or curve downwards, making the nail appear much narrower. Pincer nails may affect one or more digits and can sometimes lead to discomfort or difficulty in maintaining proper nail care.

The pincer shape can restrict nail growth and may also be associated with various underlying factors, such as genetics or previous trauma to the nail. Understanding this condition is important for nail technicians because it may influence how they perform manicures and pedicures, or even necessitate referral to a medical professional for further evaluation or treatment.

Other conditions, while they may affect the nails in different ways, do not primarily increase the nail's curvature in the same manner as pincer nails do. This distinction is crucial for accurately identifying nail issues in clients.
