If your nails are not smooth, you may be lacking zinc, calcium, or vitamin A, or you might be developing a skin condition such as eczema or psoriasis. Pitting, or tiny dents in the nail surface, is often linked to these issues. These changes can appear as small depressions or wave-like patterns. Psoriasis is well known for causing nail pitting, and the severity of nail changes often matches the severity of skin symptoms. Other conditions like alopecia areata and lichen planus can also cause nail pitting. While good nail care can help prevent further damage, treatment usually focuses on managing the underlying condition rather than the nail changes themselves.
