Thumb nails have stripes. What's going on?

The thumb nail has striations mainly because of the lack of calcium in the body, or the nail has malnutrition and fungal infection caused by the phenomenon. If the nail has been more serious trauma, but the nail bed is intact, this situation will normally recover with time. If necessary, you can use anti-fungal or vitamin drugs to do comprehensive treatment. Patients should keep their hands clean at ordinary times, eat more foods with vitamins and high-quality protein, which can help enhance the body's disease resistance and reduce the occurrence of striae.
