Doctor Explains What It Means If You Have Ridges On Your Fingernails

Have you ever noticed ridges on your fingernails and wondered what they mean? According to Dr. Ross Perry, a skin expert at Cosmedics, nail ridges can sometimes be a reflection of what’s happening inside your body. While most ridges are harmless, some may be linked to underlying health concerns.

What Causes Nail Ridges?

Ridges may develop due to several factors, ranging from natural aging to nutritional deficiencies. Dr. Perry explains that lacking essential nutrients can play a role:

Vitamin A deficiency

Low protein levels

Low calcium intake

Severe iron deficiency, which in more extreme cases can cause deeper, more noticeable ridges.

Dehydration and certain skin conditions may also contribute.
