If your nails lack smoothness, you might be low on zinc, calcium, or vitamin A, or facing a skin condition like eczema or psoriasis. Pitting, or small dents on the nail surface, often ties to these concerns. These changes can show as tiny dips or wavy patterns. Psoriasis is notorious for causing nail pitting, with the extent of nail damage often mirroring skin flare-ups. Other issues like alopecia areata and lichen planus can also trigger pitting. While proper nail care helps limit further harm, treatment usually targets the root condition rather than just the nail symptoms.
