Rivets in fingernails, often referred to as "nail ridges," can be caused by various factors, including aging, nutritional deficiencies, or health conditions. Vertical ridges may develop due to natural aging processes, while horizontal ridges, known as Beau's lines, can indicate trauma, illness, or systemic issues. Additionally, dehydration or a lack of certain vitamins and minerals can contribute to the appearance of these ridges. It's advisable to consult a healthcare professional if there are sudden changes in nail texture.
