Vertical ridges are often a sign of aging
Ridges in your nails are usually harmless but can mean different things. Vertical ridges are often a sign of aging, while horizontal ridges can point to issues like malnutrition, serious nail injury, or Beau’s lines. Beau's lines are horizontal ridges or dents in one or more of your fingernails or toenails. They’re a sign that an illness, injury or skin condition interrupted your nail growth.
Vertical ridges commonly develop in older adults. In some cases, ridges may be a sign of health problems like vitamin deficiencies or diabetes. Deep horizontal ridges, called Beau’s lines, may suggest a serious condition. Beau's lines are grooves or indentations running across your nail. Horizontal nail ridges usually develop when nail growth is disrupted by something. Nail trauma is one possible culprit. Using artificial nails or getting gel manicures for long periods can also harm the nails and lead to horizontal ridges.
Aging is one of the most common causes of tiny vertical nail ridges (onychorrhexis), which extend from the bottom of the nail to the tip. Ridges in the fingernails are usually signs of aging. However, it’s important to pay attention to fingernail ridges and other nail changes. These might be the first signs of a serious medical problem.

Horizontal ridges can point to malnutrition
Ridges in your nails are usually harmless but can sometimes indicate different health issues. Vertical ridges are often a sign of ageing, while horizontal ridges can point to issues like malnutrition, serious nail injury, or Beau's lines.
Beau's lines are horizontal ridges or dents in one or more of your fingernails or toenails. They are a sign that an illness, injury, or skin condition interrupted your nail growth. Treating the underlying cause will allow new, smooth nails to grow again. Horizontal ridges can also be caused by using artificial nails or getting gel manicures for long periods.
Malnutrition is a condition that occurs when the body does not get enough nutrients. This can be due to a poor diet, digestive problems, or certain medical conditions. Malnutrition can lead to a variety of health problems, including weight loss, fatigue, and weakened immune system. It can also cause changes in the nails, such as horizontal ridges. This is because the body may not be getting enough of the nutrients needed for nail growth, such as protein, vitamins, and minerals.
If you notice horizontal ridges in your nails, it is important to see a doctor or dermatologist to determine the underlying cause. They may ask about your diet and medical history and perform tests to check for malnutrition or other health issues. Treating the underlying cause of the ridges can help improve nail health and overall health. This may include making changes to your diet, taking supplements, or treating any underlying medical conditions.

Horizontal ridges can be caused by nail trauma
Ridges in your nails are usually harmless but can sometimes indicate a more serious medical problem. Vertical ridges are often a sign of ageing, while horizontal ridges can point to issues like malnutrition, serious nail injury, or Beau's lines.
Horizontal ridges, also known as Beau's lines, are grooves or indentations that run across your nail. They can develop when nail growth is disrupted by something, such as nail trauma. This could be caused by an injury, such as closing a door on your finger or dropping something heavy on your toe. Using artificial nails or getting gel manicures for long periods can also harm the nails and lead to horizontal ridges.
Beau's lines can also be a sign that an illness or skin condition has interrupted your nail growth. Conditions that can cause Beau's lines include peripheral vascular disease, diabetes, hypothyroidism, and Raynaud's disease. These conditions interfere with blood flow to the nail, which can disrupt nail growth and cause the formation of horizontal ridges.
If you notice horizontal ridges on your nails, it is important to consult a medical professional, especially if you suspect an underlying medical condition. Treating the underlying cause will allow new, smooth nails to grow again.

Horizontal ridges can be caused by artificial nails or gel manicures
Ridges in your nails are usually harmless but can sometimes indicate an underlying health problem. Vertical ridges are often a sign of ageing, while horizontal ridges can point to issues like malnutrition, serious nail injury, or Beau's lines. Beau's lines are horizontal ridges or dents in one or more of your fingernails or toenails. They are a sign that an illness, injury or skin condition interrupted your nail growth. Horizontal ridges can also be caused by artificial nails or gel manicures.
Artificial nails and gel manicures can harm the nails and lead to horizontal ridges. This is because the application of these products can disrupt nail growth. When you get a gel manicure, your natural nails are filed down and then coated with a gel that is cured under a UV light. This process can weaken your nails and make them more prone to breakage and splitting. Similarly, artificial nails are often applied with strong adhesives that can damage your natural nails and disrupt their growth.
If you notice horizontal ridges on your nails after getting artificial nails or gel manicures, it's important to give your nails a break and let them grow out naturally. You can also try using nail-strengthening treatments to help restore your nails' health.
In addition to artificial nails and gel manicures, there are other factors that can contribute to the development of horizontal ridges. Nail trauma, such as closing a door on your finger or dropping something heavy on your toe, can cause horizontal ridges. Conditions that interfere with blood flow to the nail, including peripheral vascular disease, diabetes, hypothyroidism, and Raynaud's disease, can also lead to horizontal ridges.
It's important to pay attention to any changes in your nails, as they can sometimes be an indication of a serious medical problem. If you are concerned about the appearance of horizontal ridges on your nails, it is recommended to consult with a dermatologist or healthcare professional for further evaluation and advice.
