Thick toenails are usually harmless and are often caused by fungal infections, which can be treated with antifungal medication. Thick toenails can also be caused by injuries, ill-fitting shoes, and underlying conditions such as psoriasis, diabetes, and autoimmune disorders. While thick toenails can take a long time to grow out, typically growing at a rate of 1 millimeter per month, there are several ways to promote healthy toenail growth and reduce the appearance of thickness.

What You'll Learn
Thick toenails are often a result of fungal infections
Dermatophytes are responsible for 90% of toenail fungal infections. However, other types of fungi can also infect toenails, and these infections can be quite contagious. Walking barefoot in public areas, using public locker rooms or showers, or walking around swimming pools can expose you to toenail fungi. Additionally, wearing sweaty or ill-fitting shoes can promote the growth of the infection.
The appearance of infected toenails can vary. They may change colour, appearing white, yellow, or brown, and may look chalky or cloudy. The nails can thicken and become misshapen, with a rough texture that makes them challenging to care for. In some cases, the nail may separate from the nail bed.
Treating thick toenails caused by fungal infections can be challenging and time-consuming. Oral antifungal medications have traditionally been used, but due to potential side effects from prolonged use, topical medications are now often preferred. A combination of oral and topical treatments may also be effective. In severe cases, a doctor may need to remove part of the infected nail to stop the infection from spreading. While thick toenails are typically harmless, it is important to consult a healthcare provider to determine the best course of treatment.
There are also some home remedies that have been anecdotally shown to be effective. For example, a mixture of one part apple cider vinegar and two parts warm water can be used to reduce fungal growth and spread. However, it is important to consult a dermatologist before attempting any home remedies.

Thick toenails can be caused by injury or trauma
Thick toenails are typically harmless and are often caused by fungal infections. However, they can also be a sign of other health conditions or underlying causes, such as physical injury or trauma to the nail bed.
Causes of Thick Toenails
The main cause of thick toenails is onychomycosis, a type of nail fungus that affects more than 10% of the population. This fungus invades cracks in the toenails and grows under the nail bed, causing the nail to thicken and change in appearance. Other factors that can contribute to thick toenails include older age, psoriasis, and physical injury or trauma to the nail.
Treatment Options
If thick toenails are caused by a fungal infection, it is important to seek treatment to prevent further issues. Oral antifungal medications have traditionally been used to treat onychomycosis, but due to their potential side effects and long treatment durations, topical medications are often preferred. A combination of oral and topical treatments may also be effective in eradicating the fungus. Additionally, keeping your toenails clean, trimmed, and filed can help slow the growth of thick nails.
Underlying Conditions
In some cases, thick toenails may indicate an underlying condition such as yellow nail syndrome, a rare autoimmune disorder that causes nails to thicken and turn yellow. This syndrome is often associated with respiratory problems and swelling in the arms and legs. Other underlying conditions that can cause thick toenails include congenital disorders, chronic illnesses, or immune disorders.
Prevention
To prevent thick toenails caused by fungal infections, it is important to maintain proper nail care and foot hygiene. Keep your toenails clean, trimmed, and moisturized. Wear socks that wick away moisture and use foot powder to prevent excessive sweating. Avoid spending prolonged periods in sweaty or ill-fitting shoes, as this can create an ideal environment for fungal growth.

Thick toenails may be a sign of ageing
Thick toenails are a common issue, affecting over 10% of the population. While they are typically harmless, they can be a sign of ageing or an underlying health condition. Onychomycosis, or nail fungus, is the most common cause of thick toenails. This fungal infection invades cracks in the toenail and grows under the nail bed, causing the nail to thicken and change colour. It can also result in a rougher texture, making toenails more difficult to care for.
Fungal infections are difficult to cure and can take a long time to treat—up to 12 to 18 months, according to the American Academy of Dermatology. During this time, you may experience a recurrence of the infection. Treatment options include oral and topical antifungal medications, with a combination of both sometimes being used. In extreme cases, a doctor may need to remove part of the infected nail to stop the spread.
To prevent and treat fungal infections, it is recommended to wear sweat-absorbing socks and shoes in areas where you may come into contact with nail fungus, such as pool areas and locker rooms. Keeping toenails trimmed and filing them two to three times a week can also help to slow growth. Additionally, home remedies such as foot soaks with baking soda, Epsom salt, or vinegar can help to stop fungal growth and promote healthy nail growth.
While less common, thick toenails can also be a sign of other health conditions, such as psoriasis, autoimmune disorders, or chronic illnesses. In some cases, thick toenails may be caused by physical injury or pressure on the toe. If you are concerned about thick toenails or experience discomfort, it is important to speak with a healthcare provider to determine the underlying cause and appropriate treatment options.

Thick toenails can be treated with antifungal medication
Thick toenails are often caused by onychomycosis, a toenail fungus that affects more than 10% of the population. This fungus invades cracks in the toenails and grows under the nail bed, and it is more common in diabetics or those on immuno-suppressant drugs. Other causes of thick toenails include onychauxis (a form of nail overgrowth) and onycholysis (when the nail separates from the nail bed).
Topical antifungal medications can also be applied directly to the nail. These are most effective when paired with oral medications. Your healthcare provider may also use lasers and special lights to treat the fungus, although these are not typically used as first-line treatments.
In addition to medical treatments, there are home remedies that may be effective for some people. For example, research suggests that vinegar is an effective remedy for treating thick toenails. A ratio of one part apple white vinegar and two parts warm water is recommended to reduce fungal growth and spread. However, it is highly recommended to consult your dermatologist before trying home remedies.
While thick toenails are usually harmless, they can be frustrating and difficult to treat. It is important to be patient and persistent with treatment, as it can take a long time to see results, and the fungus may return. Practicing good hygiene and foot care can help reduce the chances of toenail fungus returning.

Thick toenails can be prevented by good foot hygiene
Thick toenails are often a symptom of a fungal infection, known as onychomycosis, which affects more than 10% of the population. Fungi can invade the toenails through small cracks and grow under the nail bed. This can be prevented by practising good foot hygiene.
Good foot hygiene involves keeping your feet clean and dry. Wash your feet regularly with soap and water, and dry them thoroughly with a towel. You can also use a foot powder, such as Zeasorb powder, to keep your feet dry throughout the day. It is important to change your socks a few times a day and opt for cotton socks that absorb moisture. Additionally, it is recommended to rotate your shoes so they can dry out completely between wears.
When visiting public places like locker rooms, spas, swimming pools, or nail salons, wear sandals or flip-flops to avoid direct contact with the floor. These places can harbour fungi that cause infections. It is also advisable to keep your toenails trimmed and filed. Use disinfected tools for trimming and consider filing your nails two to three times a week to slow down nail growth.
If you have a fungal infection, it is important to treat it promptly. While toenail fungus can be challenging to eradicate, various treatments can improve the appearance of your nails and prevent the spread of the infection. These include topical antifungal creams, oral antifungal medications, and home remedies like vinegar soaks or tea tree oil. In some cases, your doctor may recommend removing a portion of the infected nail to stop the fungus from spreading further.
