Onycholysis - does not need treatment
Thanks for asking on Health Care magic.
You have a condition called onycholysis where the nail separates from the nailbed. It is usually not caused due to medicines but Overzealous manicure, e.g. manicure tools pushing beneath the nail to clear dirt and overuse of nail cosmetics can lead to this condition.
I cannot assure you of the beauty of your nails but no treatment is required and spontaneous nail regrowth occurs within few months.
Let me know if you're having any further queries.
