Ageing
Ridges in your nails are usually harmless but can be a sign of ageing. Vertical ridges, which run up and down your nail, are often a sign of ageing. However, horizontal ridges, which run across your nail, can point to issues like malnutrition, serious nail injury, or Beau's lines. Ridges 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, while 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.
If you have nail ridges, it is important to talk to a healthcare provider to determine the cause and how to treat it. Ridges in your nails can be a sign of a current or past illness or injury. They may also be due to a nutrient deficiency. Treating the underlying cause can help smooth out your nails over time. While many nail ridges are harmless, those that develop suddenly, affect many nails, or are persistent or worsening may warrant a visit to a healthcare provider or a dermatologist who specializes in skin and nail diseases.
As we age, our nails can become more brittle and prone to breakage. This is because our nails tend to lose moisture and natural oils as we get older, making them drier and more prone to splitting and cracking. Ageing can also cause our nails to become thinner and more fragile, making them more susceptible to damage and ridges. Additionally, the nail bed can become thinner with age, causing the nails to appear more translucent and less pink.
While ageing is a natural process that we cannot completely avoid, there are some things we can do to help maintain healthy nails as we get older. Proper nail care is essential, including keeping nails clean, trimmed, and moisturised. Using a nail hardener or nail strengthener can also help protect nails and prevent breakage. Additionally, maintaining a healthy diet and ensuring adequate nutrient intake can support nail health. Vitamins and supplements, such as biotin, can also be beneficial for nail health, as recommended by a healthcare professional.

Malnutrition
Ridges in your nails can be harmless, but they can also be a sign of a health condition or a previous injury to your nail. Vertical ridges are often a sign of ageing, while horizontal ridges can be a sign of malnutrition, serious nail injury, or Beau's lines. Ridges can also be caused by a current or past illness, prior trauma, an infection, a skin disorder like psoriasis, or a hormonal disorder like thyroid disease. Certain nutritional deficiencies can also cause ridges in your nails, such as an iron deficiency, or a lack of zinc, vitamin A, vitamin C, or vitamin D. If you have nail ridges, it is important to talk to your healthcare provider to determine the cause and how to treat it. With time and treatment, you may see new, smoother nails grow in.
There are several types of malnutrition, including protein-energy malnutrition, micronutrient deficiencies, and obesity. Protein-energy malnutrition occurs when the body does not get enough protein and energy (calories) from the diet. This can lead to muscle wasting, oedema (fluid retention), and a weakened immune system. Micronutrient deficiencies, also known as hidden hunger, refer to a lack of essential vitamins and minerals, such as iron, zinc, and vitamins A, C, and D. These deficiencies can cause a range of health problems, including anaemia, impaired growth, and weakened bones. Obesity is a form of malnutrition that occurs when the body consumes more calories than it needs, leading to excess weight gain and an increased risk of chronic diseases such as heart disease and diabetes.
The treatment for malnutrition depends on the underlying cause and the specific nutrients that are deficient. In general, improving dietary intake and nutritional status is the primary goal. This may involve making changes to the diet, such as increasing the consumption of nutrient-rich foods or taking dietary supplements. In some cases, medical intervention may be necessary, such as with tube feeding or intravenous nutrition for those who cannot eat or absorb nutrients properly.
Preventing malnutrition involves ensuring adequate intake of all essential nutrients through a balanced diet. This includes consuming a variety of foods from different food groups, such as fruits, vegetables, whole grains, lean proteins, and healthy fats. It is also important to address any underlying medical conditions or digestive issues that may be contributing to malnutrition. For those at risk of malnutrition, such as the elderly or individuals with certain medical conditions, regular monitoring and nutritional support may be necessary to maintain optimal health.

If you notice ridges in your nails, it is important to talk to a healthcare provider to determine the underlying cause. With proper treatment, you may see new, smoother nails grow in. In some cases, home nail care may be sufficient to improve the appearance of your nails. This can include using a nail hardener or a moisturising cuticle oil to help strengthen and protect your nails.
It is important to be gentle with your nails and avoid any activities that may cause further trauma. This includes avoiding picking at your nails, biting your nails, or using your nails as tools. It is also important to protect your nails from harsh chemicals and excessive water exposure, as this can further weaken them.
If you have experienced nail trauma, it is important to be patient and allow your nails to heal. With proper care and treatment, your nails should return to their smooth and healthy state.
