Ridged Nails: Causes and Natural Solutions

Have you noticed parallel lines appearing along the length of your nails, giving them a rough and uneven appearance? You likely have ridged nails. For both men and women, it’s common to see this change on the fingertips, regardless of age. The nails are then less smooth and neat, which can be unpleasant if you like to show off beautiful hands with uniform nails. Ridged nails aren’t limited to the hands; those on the feet are also affected. There are two main types of ridges: 

• Longitudinal ridges: These form from the cuticle to the tip of the nail and are the most common. They can vary in number, affecting a single nail or several at once.

• Transverse ridges: These marks appear as horizontal indentations or depressions and can occur in isolated spots or more widely. They are generally associated with a slowing or interruption of normal nail growth.

Longitudinal ridges are often harmless, while transverse ridges may be linked to medical conditions. If you have concerns about ridged nails, it is recommended that you consult a healthcare professional for appropriate medical advice.

Several factors can cause ridges on the nails. 

What causes ridged nails?

1. Ageing of the nail: Longitudinal ridges are considered the "wrinkles of the nails" and are due to the natural ageing process. With age and after menopause in women, these ridges may become more pronounced. Normal nail aging results from the body producing less keratin, the essential component of the nail. As a result, the nail has difficulty retaining water, a phenomenon similar to the appearance of wrinkles on the skin.

2. Micro-trauma: Repeated minor impacts on the nails can cause longitudinal ridges to appear. For example, aggressive manicures, such as frequent use of semi-permanent nail polish with a buffer, can accentuate them.

3. Nutrient deficiency: Ridges on the nails are generally not linked to a calcium deficiency, but may indicate an iron deficiency. When this occurs, the nails may be deformed more significantly than just having ridges.

4. Exposure to water and cleaning products: Frequent exposure to water or cleaning products can contribute to the appearance of longitudinal ridges. It is essential to protect your nails during these activities to prevent the ridges from worsening.

Deficiencies and ridged nails

Ridges on the nails can be a sign of various nutritional deficiencies: 

• Zinc deficiency: Zinc is a mineral essential for nail growth and health, and a deficiency can manifest as ridges and deformities.

• Iron deficiency (anemia): Severe anaemia, a condition characterised by low iron levels in the blood, can cause deep ridges on the nails. Nails may become thin, brittle, and develop horizontal ridges.

• Folic acid (vitamin B9) or protein deficiency: A lack of folic acid (vitamin B9) or protein in the diet can also affect nail health and contribute to the formation of ridges.

What vitamins should you take for ridged nails?

• Biotin (Vitamin B8): Biotin plays an essential role in immune system function and the renewal of skin, nail, and hair cells. It helps increase the strength of your nails. You can find biotin in foods such as eggs, nuts, avocados, carrots, mushrooms, spinach, fish, limes, oranges, and apples.

• Vitamin B12: It helps strengthen nails and maintain their beauty. A deficiency in Vitamin B12 can weaken the body, leading to reduced keratin production and soft, brittle nails.

• Vitamin C: It is essential for promoting iron absorption, which is vital for strong nails. 

• Vitamin E: It is known for its antioxidant properties, helps slow ageing, and moisturises the nails. You can find it in various oils, including hazelnut, rapeseed, sunflower, and olive oil.

To maintain healthy nails, it is recommended to follow a balanced and varied diet that includes fruits and green vegetables rich in vitamins A, C, and B vitamins, as well as sources of protein and calcium. Also, be sure to drink enough water to keep your nails well-hydrated.

Make sure to nourish your nails regularly using suitable products, such as butters and creams specifically designed for nails. You can also opt for nourishing oils, such as borage, evening primrose, or avocado oil, gently massaging them into your nails and cuticles.

If you frequently wear nail polish, consider taking breaks to let your nails breathe. When applying polish, opt for hardeners sold in pharmacies to strengthen them. You can also make your own nail polish, to enjoy a product that’s gentle on your nails. It’s recommended to keep them short to prevent them from breaking.

In winter, when the air is dry and cold, protect your hands by wearing gloves; this will help prevent your nails from drying out. In general, be careful when handling chemicals and harsh cleaners. Finally, limiting tobacco use can also be beneficial, as smoking causes a spasm in the microcirculation of blood in the extremities, which worsens the problem of ridges on the nails.

Natural remedies to get rid of ridges on your nails

To combat ridged nails naturally, you can opt for various treatments based on oils known for their beneficial properties for nails:

• Castor oil: This oil is known for deeply nourishing nails and promoting healthier regrowth. To use it, simply apply a few drops of castor oil to your nails and leave it on overnight. When you wake up, your nails will be revitalised and stronger.

• Sweet almond oil : It has nourishing properties that deeply revitalise your nails. Apply sweet almond oil by massaging it into your nails in circular motions every day to make them stronger and smoother.

Remedy for Ridged Nails Using Lemon and Olive Oil

Olive oil nourishes and moisturises the nails, while lemon helps strengthen keratin and brighten the nails. To make this soak, mix two tablespoons of olive oil and lemon juice. Soak your nails in this mixture for 10 to 15 minutes, then rinse them with warm water. This treatment will help strengthen your nails.

Herbal Tea for Brittle Nails

As this study notes, nettle contains vitamins B2 and B5, as well as zinc, which help combat brittle nails. It promotes their growth and strengthens them. Prepare an infusion by steeping two tablespoons of dried nettle leaves in 500 ml of boiling water for 10 minutes. Let it cool, then soak your nails in the infusion for 15 minutes. Repeat this treatment twice a week for stronger, more resilient nails.
