What does onycholysis refer to?

Onycholysis specifically refers to the lifting or separation of the nail plate from the nail bed. This condition often occurs at the free edge of the nail and can be caused by various factors, including trauma, infections, or various medical conditions. When a nail experiences onycholysis, it may appear discolored and can lead to further complications if not treated properly.

While the other options may describe related conditions or describe different issues with the nail, onycholysis is uniquely characterized by the detachment of the nail plate. Understanding this condition is important for nail technicians to ensure proper care and treatments for their clients, as well as recognizing signs that may require referral to a medical professional.
