Terrys nails are a type of nail discoloration characterized by a mostly white or washed-out nail bed with a thin reddish-brown strip near the tip. They have a unique appearance that resembles ground glass. Terrys nails are entirely white with a red or brownish band at the tip. This condition most commonly affects all the nails of your fingers, but it can also occur in just one fingernail and has even been reported in toenails. Terrys nails occur when there are fewer blood vessels and more connective tissue than normal in the nail bed, causing the nails to appear white. Although Terrys nails are not harmful, they should be evaluated by a doctor, as they can be a sign of a more serious issue and may be associated with several underlying health issues.

Terrys nails may be a symptom of a chronic condition, such as liver disease, cirrhosis, peripheral vascular disease, chronic kidney failure, type 2 diabetes, HIV, congestive heart failure, skin conditions like vitiligo or tuberculoid leprosy, viral hepatitis, or other underlying health conditions. Terrys nails may also occur naturally as you get older, even if you don’t have any other underlying health conditions. People with liver disease are more likely to have Terry’s nails. Terrys nails can also appear in the elderly as a nonpathologic manifestation of normal aging.

Terrys nails dont require any medical treatment and typically subside as the underlying condition they’re associated with is treated. However, if you do need treatment, the care focuses on the underlying cause of Terry’s nails. For example, if you have liver problems or diabetes, you may take medication or change your diet.

There is no information available on the ingredients or materials that cause Terrys nails.
