Horizontal lines on the fingernails, also known as Beau's lines, can be a sign of an underlying medical condition or nutrient deficiency. While they usually indicate harmless nail trauma, they can sometimes point to more serious health issues such as severe infections, diabetes, peripheral vascular disease, or nutritional deficiencies. If you notice these lines, it is important to determine if there is a medical cause that requires treatment, especially if they are deep ridges or accompanied by other health issues.

What You'll Learn
Horizontal lines may be Beau's lines
Horizontal lines on your fingernails, also known as Beau's lines, are a sign that an illness, injury, or skin condition interrupted your nail growth. They are deep horizontal ridges or dents in one or more of your fingernails or toenails. These lines may appear on all of your nails or just a few, such as your thumbs and big toes. Beau's lines are not a disease in and of themselves and are usually harmless, but they indicate that you may have had an illness or nail damage a few weeks or months ago.
Illnesses or infections that can cause Beau's lines include a heart attack, high fever, strep infections, peripheral artery disease (PAD), and hypothyroidism. Chronic conditions that interfere with blood flow to the nail matrix, such as Raynaud's phenomenon, can also lead to Beau's lines. Additionally, skin conditions like eczema or psoriasis, as well as severe zinc deficiency or inadequate protein intake, can result in these horizontal lines. In terms of nail damage, trauma or injury to the nail matrix, such as dropping something heavy on your finger or toe, exposure to extreme cold, or getting gel manicures for long periods, can cause Beau's lines.
The thickness and number of Beau's lines can provide clues about the underlying cause. For instance, a single Beau's line on one nail may indicate an injury that affected only one finger or toe. On the other hand, multiple Beau's lines on each nail may suggest that an illness or trauma occurred more than once, and thicker lines could imply that the condition or trauma persisted for a more extended period.
If you notice Beau's lines and are unsure of the cause, it is important to consult a healthcare provider to rule out any potential health conditions. Treating the underlying cause will allow new, smooth nails to grow again. While there is no specific treatment for Beau's lines, addressing the root cause can prevent them from recurring once they have grown out. This process typically takes about six months. In the meantime, you can temporarily conceal the ridges by using a nail ridge filler and nail polish, but exercise caution as some nail products can weaken or damage your nails.

They could be caused by nutrient deficiencies
Horizontal lines on your fingernails, also known as Beau's lines, could be caused by nutrient deficiencies. While fingernail ridges are usually harmless, they can sometimes indicate an underlying health condition. In some cases, horizontal ridges can be a sign of malnutrition or vitamin deficiencies, such as a lack of iron, folic acid, or protein. A deficiency in vitamins A, B, C, D, E, zinc, or selenium may also lead to brittle nails.
Zinc deficiency, in particular, has been associated with Beau's lines and white spots on the nails. Iron deficiency, on the other hand, can cause vertical nail ridges and koilonychia, also known as spoon nails. Spoon nails have a depression in the middle, giving them a scooped-out appearance. They may be able to hold a drop of water.
If you suspect that your horizontal nail ridges are related to nutrient deficiencies, it is recommended that you consult a healthcare provider to determine the underlying cause. Treating or managing any deficiencies can help promote the growth of smoother and healthier nails. This may take several months, as fingernails only grow a few millimeters per month.
While nutrient deficiencies can be a factor, it is important to note that horizontal nail ridges can also be caused by other factors, such as nail trauma, certain illnesses, or conditions that affect blood flow to the nail. Consulting with a healthcare professional can help identify the specific cause and determine an appropriate treatment plan.

Horizontal lines can be caused by nail trauma
Horizontal lines on the fingernails, also known as Beau's lines, can be caused by nail trauma. An injury to the nail, such as closing a door on your finger or dropping a heavy object on your toe, can result in these horizontal ridges. Additionally, the use of artificial nails, gel manicures, or certain chemicals found in nail polish removers and cuticle softeners can also contribute to the formation of Beau's lines.
Beau's lines are often deep grooves that run horizontally across the fingernail, and they are typically indicative of an underlying condition or interruption in nail growth. In some cases, these horizontal ridges may be accompanied by changes in nail colour, texture, or shape, which could suggest a more serious issue. For example, dark brown, purple, or red spots under the nails can be indicative of serious conditions such as melanoma or endocarditis. Therefore, it is important to monitor any changes in your nails and consult a healthcare provider if you notice new ridges or lines.
Nail trauma can cause bruising to form underneath the nail, leading to reddish-brown spots that will gradually fade as the nail grows out. While nail injuries typically do not require treatment, it is important to seek medical attention if the damage is extensive or if the discolouration occurs without any apparent cause. A doctor will be able to examine the nail and determine if there is an underlying condition that requires treatment.
While horizontal lines on the fingernails can be a cause for concern, it is important to note that they may also be a result of aging or vitamin and mineral deficiencies. In some cases, treating the underlying cause can help promote smoother and healthier nail growth. This may include addressing nutrient deficiencies, managing health conditions such as diabetes or hypothyroidism, or simply practicing proper nail care and maintaining a balanced diet. Consulting with a dermatologist or healthcare provider can help determine the appropriate course of action for treating horizontal nail ridges.

They may be a sign of an underlying condition
Horizontal lines on your fingernails can be a sign of an underlying health condition and may require further investigation and management. These lines, known as Beau's lines, can indicate a previous episode of illness or injury. They are often associated with systemic or localised conditions that temporarily disrupt nail growth. Beau's lines are typically indentations that run across the nail, perpendicular to the growth direction, and can appear as one or multiple grooves.

Horizontal lines, or ridges, on your fingernails are known as Beau's lines. They are a sign that an illness, injury, or skin condition interrupted your nail growth. These lines can appear after a serious illness, such as a heart attack, high fever, mumps, pneumonia, measles, or syphilis. They can also be caused by nutrient deficiencies, such as a zinc or protein deficiency. In some cases, Beau's lines can indicate a chronic underlying condition, such as diabetes, peripheral artery disease, or hypothyroidism. Mental and emotional stress can also cause Beau's lines. If you notice Beau's lines and are unsure of the cause, it is important to see a healthcare provider to rule out any possible health conditions. Your healthcare provider will examine your nails and take a health history to determine the underlying cause. The thickness and number of Beau's lines can provide clues about the cause. For example, a single Beau's line on one nail may indicate an injury to that finger, while lines on all your nails can suggest an illness or stress caused them. Repeated Beau's lines could be a sign of a chronic condition that keeps interrupting your nail growth. Treating the underlying cause of Beau's lines will allow new, smooth nails to grow again. If the cause is a nutrient deficiency, addressing this deficiency will usually result in nail growth returning to normal. If the cause is a previous illness, the lines should gradually grow out. However, if new Beau's lines keep appearing, it is important to see a healthcare provider to rule out any underlying health conditions. While Beau's lines themselves are not harmful, they can be a sign of an underlying condition that requires medical attention. Therefore, it is important to monitor your nails for any changes and seek medical advice if you are concerned.
