How did you cause your gray nails

The main cause of onychomycosis is fungal infection on the deck, which may be caused by various factors, such as deck trauma, fungal infection on the deck, such as dermatophyte infection, and ultimately forming onychomycosis. Although the deck was not injured, some people suffered from tinea manus for a long time and suffered from tinea manus repeatedly, which may cause fungal infection of the deck edge tissue. With the development of the disease, the entire nail may become gray, which causes gray nails. The above health science knowledge is only for reference. The specific situation needs to be checked in a regular hospital and judged by a professional doctor.
