Vertical ridges are often a sign of ageing
Vertical ridges on nails are often a sign of ageing. This is one of the most common causes of tiny vertical nail ridges (onychorrhexis), which extend from the bottom of the nail to the tip. Vertical ridges are usually harmless but can occasionally be a sign of an underlying medical issue. They can also be caused by improper nail care, nail trauma, vitamin deficiencies, or a nutrient deficiency.

Horizontal ridges can be caused by malnutrition
Ridges in your nails can be a sign of a current or past illness, or a previous injury to your nail. They can also be harmless, and are usually nothing to worry about. Vertical ridges are often a sign of ageing, while horizontal ridges can be caused by malnutrition, serious nail injury, or Beau's lines. They can also be a sign of a vitamin deficiency.
Horizontal ridges, also known as transverse lines, extend from one side of the nail to the other. They can be caused by a lack of nutrients in the diet, such as a deficiency in vitamins or minerals. This can lead to the nail bed becoming damaged, which in turn causes the ridges to form.
Malnutrition can cause a variety of issues with the body, including problems with the nails. A lack of nutrients can lead to the nail bed not receiving the necessary nutrients for healthy growth, which can result in the formation of ridges. In some cases, malnutrition can also cause the nails to become brittle or fragile, which can make them more susceptible to breaking or chipping.
If you are experiencing horizontal ridges in your nails, it is important to consult a healthcare professional or dermatologist to determine the underlying cause. They may recommend a change in diet or the addition of supplements to address any nutrient deficiencies. Treating the underlying cause of the ridges will usually result in smoother nails over time.
