What Causes Ridges on Your Nails?

What Are Nail Ridges?

Nail ridges are raised lines on the surface of the nail. They come in two directions, and the direction tells you most of the story. Vertical ridges run from your cuticle to the tip of your nail. Horizontal ridges run side to side across the nail. Vertical ridges are common and usually harmless. Horizontal ridges are less common and worth paying attention to.

What Causes Vertical Ridges?

Vertical ridges are most often simply a sign of time. As we get older, our nails produce new cells a little less evenly, the same way skin gradually changes, and those subtle differences show up as fine lengthwise lines. Genetics play a part too, so if your parents have ridged nails, chances are you will as well.

Dryness makes them more noticeable. Nails, like skin, hold moisture, and when they're dehydrated the surface looks duller and more textured. Frequent hand washing, harsh removers, and cold weather all dry the nail plate out and make existing ridges stand out more than they otherwise would.

What About Horizontal Ridges?

Horizontal ridges, sometimes called Beau's lines, form when nail growth is briefly interrupted. That can happen after an illness with a fever, a knock or injury to the nail, a period of high stress, or a gap in nutrition. The nail keeps a record: by the time the line has grown out enough to see, the event that caused it has usually passed. If horizontal ridges appear across several nails at once, or keep coming back, it's worth mentioning to your doctor.

Everyday Habits That Make Ridges Worse

A few common habits rough up the nail surface and exaggerate ridging:

• Peeling or picking off gel polish, which lifts layers of the nail with it
• Aggressive filing or buffing that thins the nail plate
• Skipping cuticle oil, leaving the nail dry and brittle
• Using nails as tools for opening, scraping, and prying

How to Care for Ridged Nails

The good news is that ridged nails respond well to consistent, gentle care. Keep the nail and cuticle hydrated with a daily oil or cream, wear gloves for cleaning and dishes, and let a professional handle removal when you're wearing gel. A regular manicure keeps the nail surface conditioned and tidy, and a soft touch of colour or a sheer finish evens out the look of fine ridges beautifully.
