What can cause onycholysis in a nail?

Onycholysis refers to the separation of the nail plate from the nail bed, which can be a distressing condition for clients and a significant concern for nail technicians. The correct answer highlights that trauma, chemical exposure, or fungal infections are the primary causes of onycholysis.

Trauma can result from physical damage inflicted on the nail, such as impact or pressure, leading to separation from the nail bed. This is common in individuals who engage in activities that put their nails at risk. Chemical exposure, particularly to harsh nail products or irritating substances, can compromise the health of the nail and surrounding skin, also resulting in onycholysis. Additionally, fungal infections are known to invade the nail plate and lead to various nail disorders, including separation.

In contrast, consistent polishing, excessive filing, and an improper nail care routine can contribute to nail damage and issues, but they are not direct causes of onycholysis. While these factors can weaken nails or cause them to become unhealthy, onycholysis specifically relates to more acute triggers like trauma or infections. Therefore, understanding the underlying causes is essential for effective prevention and treatment within nail technology practices.
