Ridges in your nails are usually harmless, but they can sometimes indicate a more serious health problem. Vertical ridges are often a sign of ageing, while horizontal ridges can point to malnutrition, nail injury, or Beau's lines. Beau's lines are deep grooves that run the width of your nail, indicating that something slowed or stopped your nails from growing for a while. Other causes of nail ridges include improper nail care, nail trauma, vitamin deficiencies, and certain medical conditions.

Vertical ridges are often a sign of ageing
Vertical ridges are usually harmless, but they can also be a sign of improper nail care, nail trauma, vitamin deficiencies, or a more pressing medical condition. For example, iron deficiency may cause vertical ridges in your nails. Other vitamins that can contribute to nail health 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 needed to understand the full extent of its benefits.
Horizontal ridges, on the other hand, can point to issues like malnutrition, serious nail injury, or Beau's lines. Beau's lines are deep grooves that run the width of your nail, indicating that something slowed or stopped your nails from growing for a while. If your nails completely stop growing, you may see a gap or a place on your nail that is missing. This condition is called onychomadesis.
Other nail abnormalities can include changes in colour, texture, and shape, which may be caused by a bacterial or fungal infection. Chronic picking or rubbing of the skin behind the nail can cause median nail dystrophy, resulting in a lengthwise split or ridged appearance of the thumbnails. Long-term exposure to moisture or nail polish can also cause nails to peel and become brittle.

Horizontal ridges can point to malnutrition, nail injury or Beau's lines
Bumpy nail beds can be harmless, but they can also indicate a variety of 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 grooves that run the width of your nail, indicating that something has slowed or stopped your nails from growing for a while. This could be caused by malnutrition, as certain nutritional deficiencies can affect your nails. For example, iron deficiency may cause vertical ridges in your nails, while zinc and vitamins A, C, and D can also contribute to nail health.
Horizontal ridges can also be caused by nail trauma or injury. Crushing the base of the nail or the nail bed may cause a permanent deformity, while chronic picking or rubbing of the skin behind the nail can cause median nail dystrophy, resulting in a lengthwise split or ridged appearance of the thumbnails. Long-term exposure to moisture or nail polish can also cause nails to become brittle and peel, which may contribute to horizontal ridges.
In some cases, horizontal ridges on the nails may be a sign of a more pressing medical condition. Problems in the liver, lungs, and heart can show up in your nails. For example, white nails, also known as leukonychia, can indicate trauma, anemia, dietary deficiencies, heart or kidney disease, or even poisoning. If the nails are mostly white with darker rims, this can be a sign of liver problems, such as hepatitis. Therefore, it is important to pay attention to any changes in your nail health and consult a healthcare professional if you have any concerns.

Ridges can be caused by improper nail care, nail trauma, vitamin deficiencies or a medical condition
Ridges in your nails are usually harmless, but they can be caused by a variety of factors. Vertical ridges are often a sign of ageing, possibly due to a slowing of cell turnover, while horizontal ridges can point to issues like malnutrition, serious nail injury, or Beau's lines. Beau's lines are deep grooves that run the width of your nail, indicating that something slowed or stopped your nails from growing for a while.
Ridges can also be caused by improper nail care, such as chronic picking or rubbing of the skin behind the nail, which can cause median nail dystrophy and give your thumbnails a lengthwise split or ridged appearance. Long-term exposure to moisture or nail polish can also cause nails to peel and become brittle.
Certain nutritional deficiencies can also affect your nails. For example, iron deficiency may cause vertical ridges in your nails. Other vitamins that can contribute to nail health 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 needed to understand the full extent of its benefits.

Long-term exposure to moisture or nail polish can cause nails to peel and become brittle
Bumpy nail beds, or ridges, are usually harmless but can sometimes indicate a 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 deep grooves that run the width of the nail, indicating that something has slowed or stopped your nails from growing for a while. This could be due to a nutritional deficiency, such as an iron, zinc, or vitamin A, C, or D deficiency.
To prevent this, it is important to give your nails a break from nail polish every now and then and to avoid prolonged exposure to water. When wearing nail polish, use a base coat to create a protective barrier between the nail and the polish. Also, make sure to moisturise your nails and cuticles regularly with a cuticle oil or hand cream to help keep them strong and healthy.
If your nails are already peeling and brittle, there are a few things you can do to help repair them. Try using a nail strengthener or hardener to help reinforce the nail and prevent further peeling. You can also gently buff the surface of the nail to smooth out any ridges or peeling. Finally, make sure to keep your nails trimmed and filed to a smooth edge to prevent them from catching and tearing.

Fungus or yeast can cause changes in nail colour, texture and shape
Bumpy nail beds can be caused by a variety of factors, including aging, malnutrition, nail injury, and vitamin deficiencies. Fungus or yeast can also cause changes in nail colour, texture and shape. For example, long-term exposure to moisture or nail polish can cause nails to peel and become brittle. In addition, bacterial infections may cause a change in nail colour or painful areas of infection under the nail or in the surrounding skin.
Fungal infections of the nail, also known as onychomycosis, are a common problem that can affect people of all ages. Fungi thrive in warm, moist environments, so they often occur in people who frequently wear tight-fitting shoes or who have sweaty feet. Fungal infections can also be caused by walking barefoot in damp areas, such as public showers or swimming pools.
The most common symptom of a fungal nail infection is a change in nail colour, which can range from white or yellow to brown or black. The nail may also become thickened, distorted, or brittle, and it may separate from the nail bed. In some cases, there may be a foul odour.
Yeast infections of the nail, also known as candida paronychia, are less common than fungal infections. Yeast thrives in warm, moist environments, so they often occur in people who have their hands or feet constantly in water, such as dishwashers or swimmers. Yeast infections can also be caused by frequent exposure to chemicals or detergents, which can disrupt the natural balance of bacteria and yeast on the skin.
The most common symptom of a yeast nail infection is redness, swelling, and pain around the nail. The nail may also become thickened, distorted, or brittle, and it may separate from the nail bed. In some cases, there may be a discharge of pus.
