Vertical ridges are often a sign of ageing
Vertical ridges on the fingernails are usually harmless and are often a sign of ageing. This is known as onychorrhexis, and it can happen as you get older, causing your nails to become ridged, dry, brittle or thick. This is a normal part of the ageing process and is one of the most common causes of onychorrhexis.
Vertical ridges are sometimes called longitudinal striations or bands. They are furrows that run from the tip of your fingernail down to the cuticle. Research from 2015 suggests that slight vertical ridges in fingernails often develop in older adults, possibly due to a slowing of cell turnover. This is when new skin cells produced below the surface of your skin rise up to take the place of dead cells on the surface.
While vertical ridges are usually nothing to worry about, they can also be a sign of another health problem. Conditions that can cause onychorrhexis include heart and circulatory diseases. Decreased circulation to the fingertips can also cause vertical ridges in nails.

Horizontal ridges can be caused by a serious nail injury
Ridges in your nails are usually harmless but can sometimes indicate other health problems. Vertical ridges are often a sign of ageing, while horizontal ridges can be caused by a serious nail injury, malnutrition, or Beau's lines.

Horizontal ridges can also be caused by a serious nail injury. If you have injured your nail, it may take up to six months for it to grow out and for the horizontal ridges to disappear. In the meantime, you can try to prevent further damage by moisturising your hands or using topical ointments. If you are concerned about the appearance of horizontal ridges on your nails, it is best to consult a dermatologist for advice on treatment.
There are other potential causes of horizontal ridges in your nails. These include decreased circulation to your fingertips, stripping your nails with solvents during manicures, tumours, and certain dermatological conditions. If you are experiencing other symptoms such as texture changes in your nails, it is important to seek medical advice to determine the underlying cause.
While vertical ridges are usually nothing to worry about, they can sometimes be a sign of a health condition. Conditions that can cause vertical ridges include heart and circulatory diseases.

Vertical ridges can be caused by decreased circulation to fingertips
Vertical ridges in fingernails are usually harmless and are often a sign of ageing. However, they can also be caused by decreased circulation to the fingertips.
