5 Reasons You Have a Black Toenail, According to a Dermatologist
Your nails can say a lot about your health: Discoloration, brittleness, and breakage are annoying to deal with on your fingers, but they’re also signs you should watch out for on your toes. One problem you definitely shouldn’t ignore? A black toenail. Sure, it can be a cosmetic nightmare when you want to rock your favorite comfy sandals, but it can also signal a potentially serious problem.
“If we’re talking about just one black toenail, there are some reasons that are concerning, and there are some that are very benign,” explains Nava Greenfield, M.D., a dermatologist at Schweiger Dermatology Group in New York City. “I ask myself, ‘Am I seeing the black toenails on both sides of the feet, or just one toe? Is it symmetrical?’”
Discolored toenails are pretty common, Dr. Greenfield says, so don’t feel embarrassed or ashamed—the condition is likely no fault of your own.
