Pits in your nails
Indentations, or pits in the nails, are usually on fingernails instead of toenails. Trauma, hair loss, or nail psoriasis might cause these indentations, says Shari Lipner, MD, a dermatologist at NewYork-Presbyterian and Weill Cornell Medicine. Patients with nail psoriasis can also have underlying arthritis or inflammation, too, Medical News Today reports.
