What term describes the loosening or separation of the nail?

The term that describes the loosening or separation of the nail is onycholysis. This condition occurs when the nail plate begins to detach from the nail bed, which can happen for various reasons, such as trauma, fungal infections, or exposure to certain chemicals. Understanding onycholysis is important in cosmetology, as it can affect the overall health and appearance of the nails.

Onychomycosis refers specifically to a fungal infection of the nail, which does not primarily pertain to separation. Onychauxis is a condition characterized by thickening of the nails, while leuconychia refers to white spots or discoloration of the nails, neither of which involve separation. Recognizing these terms and their meanings is crucial for proper diagnosis and treatment in nail care.
