If your nails are bumpy or have dents, you might lack zinc, calcium, or vitamin A, or you could be developing a skin condition like eczema or psoriasis. Pitting, or small dents, is often linked to these problems. These changes can appear as tiny holes or waves. Psoriasis often causes nail pitting, and nail changes usually match how severe the skin symptoms are. Other conditions, such as alopecia areata and lichen planus, can also cause nail pitting. Good nail care helps, but treatment usually targets the underlying disease.
