What You'll Learn
Vertical ridges are often a sign of ageing
Vertical ridges in your nails are usually harmless and are often a sign of ageing. These ridges are sometimes called longitudinal striations or bands and are furrows that run from the tip of your fingernail down to the cuticle. They are common in older adults and are 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 discarding dead cells from the surface.
However, vertical ridges can also be a sign of improper nail care, nail trauma, vitamin deficiencies, or even a more pressing medical condition. For example, iron deficiency may cause vertical ridges in your nails. Other vitamins that can contribute to the health of your nails include zinc and vitamins A, C, and D. According to 2018 research, biotin is also highly recommended to aid in nail health, but more research is still needed to understand the full extent of its benefits.
Horizontal ridges, known as Beau's lines, can point to issues like malnutrition, serious nail injury, or a more serious underlying medical condition. Beau's lines can be caused by an illness or stress, and multiple lines on each nail may mean that an illness or trauma happened more than once. Thicker Beau's lines may be a sign that an illness or trauma lasted a longer time.

Horizontal ridges can point to malnutrition, serious nail injury or Beau's lines
Ridges in your nails are usually harmless but can sometimes indicate underlying health issues. Vertical ridges are often a sign of ageing, while horizontal ridges can point to malnutrition, serious nail injury, or Beau's lines. Beau's lines are deep horizontal grooves that run the width of the nail, indicating that something has slowed or stopped your nails from growing for a while. Beau's lines can be caused by an illness or stress, and multiple lines on each nail may mean that an illness or trauma occurred more than once. Thicker Beau's lines may suggest that an illness or trauma lasted a longer time. While there is no treatment for Beau's lines, treating the underlying cause can prevent them from recurring once the nails grow out.
