Vertical Ridges on Nails

Furrows that extend from the tip of your fingernail to the cuticle are known as vertical ridges. They are sometimes known as bands or longitudinal striations.

Age-related changes in cell turnover may explain why older persons’ fingernails frequently develop little vertical ridges. This occurs when fresh skin cells created beneath the skin’s surface emerge to replace the surface’s dead cells.

Vertical ridges and nail alterations that cause them to become concave or spoon-shaped can also be brought on by iron deficiency anemia, according to Trusted Source.

Horizontal nail ridges

Research from 2018 indicates that Beau’s lines, which are deep horizontal ridges, are frequently signs of a dangerous ailment. In some cases, they may even stop nail growth while the underlying disease is being treated. If Beau’s lines emerge, acute renal illness may also be present.

The 2015 study that was previously stated suggests that the development of Beau’s lines on all 20 nails may be a sign of:

• mumps
• parathyroid disease
• unmanaged diabetes
• syphilis
• respiratory conditions
• illnesses that cause prolonged high fevers
• zinc deficiency

Chemotherapy may also cause Beau’s lines.

Red or brown spots may appear beneath your nails as a result of nail trauma. Without having suffered nail injuries, if you see dark brown, black, or red color changes under your nails, it could be a sign of a more serious illness like endocarditis or melanoma.
