The fingernail is a hard, protective covering made of a protein called keratin that grows at the end of each finger. It serves to protect the sensitive tips of our fingers and helps us with tasks such as picking up small objects and scratching. The nail also acts as a tool for grooming and can be a reflection of our overall health. **

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. It is important to regularly clean under the fingernails to prevent the buildup of dirt and bacteria. 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. **

Fingernail fungus, also known as onychomycosis, is a common condition caused by a fungal infection. It can occur when fungi enter the nail through a small cut or crack, leading to discoloration, thickening, and brittleness of the nail. Fingernail fungus can be unsightly and may cause discomfort, and it is important to seek treatment to prevent it from spreading to other nails. Treatment options include antifungal medications, topical treatments, and in some cases, surgical removal of the nail. **

It is important to consult a healthcare professional to determine the underlying cause and receive appropriate treatment. **
