What is the term for the loosening of the nail without shedding?

The term for the loosening of the nail without shedding is onycholysis. This condition typically involves the separation of the nail plate from the nail bed, and it can occur for various reasons, including trauma, infections, or certain skin conditions. Importantly, in onycholysis, while the nail becomes detached, it does not completely shed off, distinguishing it from other nail conditions where more severe loss of nail integrity may occur.

Understanding this condition is vital for anyone in the cosmetology field, as it helps in identifying nail health issues that may require special attention or treatment. It is also crucial for maintaining proper hygiene and care in nail applications or services. The other terms refer to different nail disorders, but onycholysis specifically pertains to the scenario described in the question.
