If You’ve Noticed Ridges in Your Fingernails, This Is What It Really Means

Noticing ridges on your fingernails can be surprising, but in most cases, they are completely harmless. Nails reflect everyday wear and natural body changes, and small variations in texture are very common.
The most frequent type is vertical ridges that run from the cuticle to the tip of the nail. These ridges often become more noticeable with age and are usually a normal part of nail growth.

Vertical ridges can also be linked to dry nails, frequent handwashing, regular use of hand sanitizer, or exposure to cleaning products. Minor bumps or pressure to the nail can make them more visible as well.
Horizontal ridges, which run side to side, are less common. They may appear after physical stress, illness, injury to the nail, or a temporary interruption in nail growth. When deep or sudden, they can be worth mentioning to a healthcare provider.
