Vertical ridges are often a sign of ageing
Ridges in your nails are usually harmless but can sometimes be a sign of a health condition or nutrient deficiency. Vertical ridges are often a sign of ageing, while horizontal ridges can point to issues like malnutrition, serious nail injury, or Beau’s lines. According to 2022 research, ridges are usually due to ageing. But they can also be a sign of improper nail care, nail trauma, or vitamin deficiencies.
As you get older, circulation to your extremities can slow down, compromising the supply of oxygen-rich blood and nutrients to your nails. This can make your nails more brittle and prone to developing ridges. 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.
If you are concerned about ridges in your nails, it is best to consult a healthcare professional. They can help determine the underlying cause and advise on any necessary treatment. Treating the cause can help you grow smoother nails.

Horizontal ridges can point to malnutrition
Ridges in your nails are usually harmless but can sometimes be indicative of a health condition or nutrient deficiency. 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 nail ridges can be a sign of malnutrition, which 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 a weakened immune system. It can also affect the health of your nails, causing them to become brittle and ridged.
Certain nutritional deficiencies can also affect your nails. For example, iron deficiency may cause vertical ridges in your nails, while a lack of zinc, vitamins A, C, and D, or biotin can also contribute to nail health issues. Treating the underlying cause of malnutrition or nutrient deficiency can help improve the appearance of your nails and prevent further ridges from forming.
According to research, ridges in nails are usually due to ageing. However, they can also be a sign of improper nail care, nail trauma, or vitamin deficiencies. In some cases, they may be indicative of a more serious medical condition. If you are concerned about ridges in your nails, it is best to consult a healthcare professional who can help determine the underlying cause and recommend appropriate treatment options.
While horizontal ridges can sometimes indicate malnutrition, it is important to note that they can also be caused by other factors. For example, they may be the result of a previous injury to the nail or a current or past illness. Additionally, some people may be genetically predisposed to weak, brittle nails that are more susceptible to ridging.

Ridges can be caused by improper nail care
Ridges in your nails are usually harmless but can be caused by a number of factors. Vertical ridges are often a sign of aging, while horizontal ridges can point to issues like malnutrition, serious nail injury, or Beau’s lines. According to 2022 research, ridges are usually due to aging. But they can also be a sign of improper nail care, nail trauma, vitamin deficiencies, or even a more pressing medical condition.
Improper nail care can cause ridges in your nail bed. This includes practices such as over-trimming, aggressive manicures, and the use of harsh nail polishes and removers. Over-trimming your nails can lead to nail bed damage, causing ridges to form. Aggressive manicures, such as gel manicures, can weaken your nails and make them more susceptible to damage and ridging. Additionally, the frequent use of harsh nail polishes and removers can strip your nails of their natural oils and moisture, leading to dryness and brittleness, which can contribute to the formation of ridges.
To prevent ridges caused by improper nail care, it is important to adopt gentle and nourishing nail care practices. This includes trimming your nails regularly but not too short, avoiding aggressive manicures, and opting for natural and nourishing nail polishes and removers. It is also essential to moisturise your nails and cuticles regularly to maintain nail health and prevent dryness and brittleness.
Additionally, maintaining a healthy diet can contribute to overall nail health and help prevent ridges. Ensuring adequate intake of vitamins and minerals, such as zinc, vitamins A, C, and D, and biotin, can promote stronger and healthier nails. A well-balanced diet that includes nutrient-rich foods can help prevent nutrient deficiencies that may contribute to the formation of ridges.
While ridges in your nails are often harmless, they can be a sign of underlying health conditions or nutrient deficiencies. If you notice persistent or severe ridges, it is advisable to consult a healthcare professional or dermatologist who can help determine the cause and provide appropriate treatment or advice.
