A fingernail is a hard, protective covering made of a protein called keratin that grows on the tips of our fingers and toes. It serves to protect the sensitive skin underneath and helps us with tasks like picking up small objects and scratching. Fingernails can also be a reflection of our overall health, as changes in their appearance or texture can sometimes indicate underlying issues. **

Fingernail dirt is not inherently toxic, but it can harbor bacteria and other microorganisms that may cause infections if it comes into contact with open wounds or is ingested.

Additionally, practicing good hand hygiene, such as washing hands with soap and water, can help reduce the risk of transferring any potential contaminants from fingernail dirt. **

Treatment options include antifungal medications, topical treatments, and in some cases, surgical removal of the nail. **
