Nail fungus, or onychomycosis, is a common condition that can affect both the fingernails and toenails, although it is more commonly found on the toes. It usually starts with mild nail discolouration or lifting and can progress to thickening, brittleness, and even nail loss if left untreated. While nail fungus can be effectively treated with medical interventions and home remedies, it often takes a long time for the infection to clear and for healthy nail growth to replace the damaged nail. So, how long does it take for nail fungus to grow and resolve?

Nail fungus symptoms
Nail fungus is a common condition that can affect both the fingernails and toenails, although it's more commonly found on the toes. It is caused by a fungus that thrives in warm, dark, and moist environments, such as the feet. The infection often starts at the edge of the nail and spreads slowly to the rest of the nail. While nail fungus is not usually a serious condition, it can cause discomfort and affect daily activities.
The symptoms of nail fungus can include mild nail discolouration, with the nail appearing slightly yellow, white, or brown. As the infection progresses, the nail may thicken, become brittle, and crumble or break easily. In more severe cases, the nail may start to detach from the nail bed and cause pain, especially when wearing shoes. The skin around the nail may also become swollen and painful if the nail breaks off.
It is important to seek treatment for nail fungus as soon as possible to prevent it from worsening and destroying the nail. A pharmacist may suggest antifungal nail medicine that is brushed onto the nail regularly for several months. If the infection is severe or does not respond to treatment, a dermatologist may recommend removing the nail to get rid of the infection. This is typically done under local anaesthesia and the nail can grow back.
The timeline for treating nail fungus can be lengthy. It may take a few months for nail fungus treatment to start working and up to 12 to 18 months for a fingernail or toenail to fully replace the damaged nail with healthy new growth. During this time, it is important to maintain good foot hygiene and follow the treatment plan provided by a healthcare professional.

Treatment options
Over-the-counter antifungal drugs
Antifungal creams, gels, sprays, and patches are available without a prescription. These include clotrimazole (Lotrimin) and terbinafine cream (Lamisil). Over-the-counter products are best for mild toenail fungus and may take months to work. It's important to note that most over-the-counter products are not strong enough to cure moderate or severe cases of toenail fungus.
Prescription antifungal drugs
For moderate to severe cases of nail fungus, prescription antifungal drugs may be necessary. These include antifungal pills like itraconazole (Sporanox) and terbinafine pills (Lamisil), which are more effective than creams and gels. Prescription drugs can have side effects, such as nausea, vomiting, and headaches, and may require monitoring by a doctor.
Nail removal
If you have a severe infection or other treatments are ineffective, a dermatologist may recommend removing the nail to get rid of the infection. This can be done surgically or nonsurgically. For nonsurgical treatment, a doctor will apply urea ointment to the infected nail surface, wrap the nail in plastic and tape, and wait for about 10 days until the nail can be removed from the nail bed.
Laser treatment
Laser treatments may also be used to get rid of nail fungus, although they are less effective than medicines.
General health and hygiene
Good general health and hygiene can help prevent fungal infections. This includes keeping your skin clean and dry, taking proper care of your nails, and washing your hands thoroughly after touching any kind of fungal infection.

Prevention methods
Nail fungus is a common condition that affects both toenails and fingernails, causing the nail to thicken, discolour and become brittle. While it is not usually a serious condition, nail fungus can be hard to treat and may lead to more severe health concerns if left untreated. Therefore, it is important to take preventative measures to lower the risk of developing nail fungus. Here are some methods to prevent nail fungus:
Keep Nails Trimmed and Clean
Trimming your nails can help prevent the spread of infection. Nails should be cut straight across and kept short, but be careful not to cut them too short that they dig into the sides of your toes. It is also important to clean your nails regularly with soap and water, especially the nails on your feet, as toenail fungus is more common. The skin around the base of the nail acts as a barrier to infection, so be sure to keep it clean as well.
Sanitize Tools and Choose Clean Nail Salons
It is important to sanitize your nail clippers, files, and scissors before each use. If you go to a nail salon, ask how often they disinfect their tools and choose a salon that sterilizes their equipment after each client.
Wear the Right Footwear
Fungus thrives in warm, moist environments, so it is important to choose breathable shoes and socks. Look for shoes made of materials like leather and socks made of synthetic fibres that pull moisture away from your feet. Avoid tight shoes and socks, and be sure to change your socks often, especially after exercising. Additionally, wear flip-flops or shower shoes in public places like pools, locker rooms, and gyms to prevent the spread of infection.
Keep Your Feet Clean and Dry
Wash your feet daily with soap and water, especially between your toes, and be sure to dry them thoroughly. Fungi multiply in warm, dark and moist places, so keeping your feet clean and dry can help prevent the growth of nail fungus.
Protect Against Injury
Be careful not to injure your nail bed or the skin around your nails, as this creates an opening for fungus to enter. Avoid biting your nails or ripping off hangnails.
By following these preventative measures, you can significantly reduce your risk of developing nail fungus.

Diagnosis process
If you suspect you have a nail fungus, it is important to seek medical advice. A doctor or dermatologist will be able to examine your nails and provide a proper diagnosis and treatment plan. The diagnosis process typically involves the following steps:
Initial Examination
Firstly, a dermatologist will visually examine your nails and the surrounding skin. They will look for signs of nail fungus, such as nail discolouration, lifting, thickening, or brittleness. It is important to check the skin because the fungus can spread and cause skin infections, such as athlete's foot.
Sample Collection
Before giving a diagnosis, the doctor may collect samples from the affected area. This can involve collecting debris from under the nail, trimming part of the nail, or scraping off a bit of skin. These samples are then sent to a laboratory for further analysis.
Microscopic Examination
In the laboratory, the samples are examined under a microscope to identify the specific type of fungus causing the infection. This information is crucial for determining the most effective treatment plan.
Additional Tests
In some cases, additional tests may be necessary. For example, a blood test may be required to check your liver function before starting certain antifungal treatments. These tests ensure that any prescribed medication will be safe and suitable for the patient.
Treatment Plan
Once a diagnosis is confirmed, the doctor or dermatologist will discuss the treatment options with you. Treatment for nail fungus can include topical medications, oral antifungal tablets or pills, or, in severe cases, nail removal. It is important to follow the treatment plan and maintain good nail hygiene to prevent the fungus from spreading or returning.
It is important to note that nail fungus can take a long time to treat, and even with successful treatment, it may take up to a year for a new, healthy nail to grow. Therefore, early detection and proactive treatment are essential to managing nail fungus effectively.

Recovery timeline
The recovery timeline for nail fungus depends on the severity of the infection and the treatment method used. Here is a detailed breakdown of the recovery process:
Initial Treatment
The first step in treating nail fungus is typically a visit to a healthcare professional, such as a pharmacist, GP, or dermatologist. They will examine the nails and nearby skin for signs of infection. This usually involves trimming and collecting samples from the nails for laboratory testing to determine the specific type of fungus.
Treatment Options
Treatment options for nail fungus vary and can include topical medications, oral antifungal drugs, or procedural interventions.
Topical Medications
Topical treatments, such as antifungal creams, gels, sprays, or patches, are commonly recommended for mild toenail fungus. These treatments are applied directly to the affected nails and may take several months to show improvement. It is important to continue using these treatments as directed, even if symptoms improve, to prevent the infection from returning.
Oral Antifungal Drugs
For more severe or persistent infections, oral antifungal pills may be prescribed. These drugs are taken orally and work systemically to clear the infection. Treatment duration can vary, but it is not uncommon to take these medications for up to six months. Side effects may include headaches, stomachaches, and potential liver damage, so regular blood tests to monitor liver function are often recommended.
Procedural Interventions
In cases of severe infection or when other treatments are ineffective, procedural interventions may be necessary. This can include nonsurgical or surgical nail removal, performed by a dermatologist or podiatrist. During this procedure, the infected nail is removed to eliminate the infection. The nail can regrow, but there is a possibility of the infection returning.
Nail Regrowth
Regardless of the treatment method, the recovery timeline for nail fungus is extended due to the slow growth rate of nails. It typically takes a fingernail four to six months to grow back completely, while a toenail can take 12 to 18 months. During this time, it is essential to maintain proper nail and foot hygiene and follow any post-treatment care instructions provided by your healthcare professional.
Full Recovery
The full recovery timeline for nail fungus can be lengthy. Even after successful treatment, it may take several months for the nail to grow back completely and for any discolouration or thickening to resolve. In some cases, it can take up to a year or more for the nail to regain its healthy, clear appearance.
It is important to note that nail fungus can be stubborn and persistent. Even with successful treatment, there is a possibility of recurrence. Therefore, it is advisable to follow preventative measures and maintain good nail hygiene to reduce the risk of reinfection.
