Nail Salon Near Me

Toenail fungus is a prevalent fungal infection that affects millions of people worldwide. This condition can be bothersome and unsightly, causing thick, discolored, and fragile nails. If left untreated, toenail fungus can spread to other nails, leading to more severe infections. In this article, we will delve into the origins, symptoms, home remedies, and medical treatments for toenail fungus.

Causes of Toenail Fungus

Toenail fungus stems from a group of fungi known as dermatophytes. These fungi thrive in moist and warm environments, making themselves at home on dead tissues like nails and skin. Here are some typical causes of toenail fungus:

Fungal Infections

Fungal infections are the primary culprits behind toenail fungus. These infections occur when fungi enter the nail bed through a minor cut or injury. People with a weakened immune system or poor blood circulation are particularly prone to fungal infections.

Poor Hygiene

Poor hygiene can also contribute to the development of toenail fungus. Fungi thrive in warm and damp environments, such as sweaty shoes and socks. Wearing soiled or moisture-laden socks creates the ideal breeding ground for fungi.

Ill-Fitting Shoes

Donning tight-fitting shoes can also trigger toenail fungus. The pressure exerted by tight shoes on the toenails can cause minor cracks or injuries. These injuries create an entryway for fungi to invade the nail bed and cause an infection.


Injuries to the toenail can lead to toenail fungus as well. When the toenail experiences trauma, it opens up an opportunity for fungi to infiltrate and incite an infection. People engaged in sports or those consistently wearing tight shoes face a higher risk of toenail injuries.

Symptoms of Toenail Fungus

Toenail fungus manifests in a variety of symptoms, including:

Thickened Nails

Toenail fungus causes thickened nails that are difficult to trim. The nails may become so thick that walking or standing becomes uncomfortable.


Toenail fungus discolors the affected nail. Nails may turn yellow, brown, or white due to the infection.

Brittle or Crumbly Nails

Toenail fungus renders nails brittle or crumbly. Nails can break or split easily, hampering everyday activities.

Unpleasant Odor

Toenail fungus can also give rise to a foul odor. The odor can be unpleasant and noticeable, especially when wearing shoes.

Home Remedies for Toenail Fungus

Although numerous medical treatments are available for toenail fungus, some people prefer to experiment with home remedies first. Here are some effective DIY solutions to combat toenail fungus:

Tea Tree Oil

Tea tree oil possesses antifungal properties that can eliminate the fungi responsible for toenail fungus. To use tea tree oil, mix a few drops with a carrier oil like coconut oil, and apply it to the affected nail.

Vinegar Soak

Vinegar, with its acidic properties, can help eradicate the fungi behind toenail fungus. Create a mixture of equal parts vinegar and water in a basin, and soak the affected foot for 15-20 minutes daily.


Garlic, containing antifungal properties, serves as an effective remedy for toenail fungus. Crush a few garlic cloves, apply the resulting paste to the affected nail, cover it with a bandage, and leave it on for 30 minutes before rinsing it off.

Coconut Oil

Coconut oil, known for its antifungal and moisturizing properties, can aid in treating toenail fungus. Apply coconut oil to the affected nail, leaving it on for at least 30 minutes before washing it off.

Baking Soda

Baking soda possesses antifungal properties that can help eliminate the fungi responsible for toenail fungus. By mixing baking soda with water, you can create a paste to be applied to the affected nail. Leave the paste on for 10-15 minutes before washing it off.

While home remedies can be effective against toenail fungus, it’s crucial to seek medical treatment if the infection persists or worsens. Medical treatments, such as oral antifungal medication or laser therapy, offer more potent and long-lasting results.
