The nails on our fingers are called “nails” because they are made up of keratin, the same protein that is the foundation of hair and skin.

Fungal infections like ringworm or athlete’s foot can cause nails to become thick, yellow, and brittle. Picking at the nails can lead to the nails’ edges breaking off. Nail
