Onycholysis is a condition in which the nail separates from the nail bed, causing the nail to lift without shedding. This can be caused by various factors such as trauma, infection, or certain medical conditions. It is not indicative of warts on the nail, brittle nails, or a contagious nail fungus. While these may also affect the appearance of the nails, they are not specifically related to onycholysis and may have different underlying causes.
