Black fingernails can be a sign of a fungal nail infection, also known as onychomycosis or mycotic nails. This occurs when a fungus attacks a fingernail, toenail, or the skin under the nail, called the nail bed. While fungal nail infections usually start mildly, they can become more serious over time, causing the nail to thicken, crumble, and loosen from the nail bed. In some cases, the nail may turn black, which can be a symptom of a rare Candida-associated fungal infection called melanonychia.

Black nail fungus is often a result of a fungal infection called onychomycosis
Dermatophytes are the cause of 90% of toenail fungal infections, with tinea unguium being the most common type of nail fungus. However, other types of fungi can also infect the nails. Nail fungi thrive in warm, moist, and dark environments, and they can spread through direct contact or by touching infected surfaces. Walking barefoot in public areas, such as swimming pools, locker rooms, or shower stalls, increases the risk of contracting nail fungus.
Mycotic nails, also known as onychomycosis, are characterised by nails that turn brown, white, or black, thicken, become fragile, and separate from the nail bed. Anyone can develop a mycotic nail, but certain factors increase the likelihood, such as having diabetes, psoriasis, or athlete's foot. The risk also increases with age, with individuals over 70 having a 50% chance of developing this condition.
Fungal melanonychia is a less common type of onychomycosis caused by fungi such as Scytalidium, Alternaria, and Exophiala, resulting in brownish or blackish discolouration of the nail. While anyone can develop this type of infection, those with weakened immune systems, athlete's foot, blood circulation problems, nail injuries, or nail surgeries are at a higher risk.
Distal (lateral) subungual onychomycosis is the most common type of onychomycosis, starting at the tip or sides of the nail and spreading from there. The nail may turn white, brown, or yellow, and the infection can spread to the nail bed. Proximal subungual onychomycosis originates from the proximal nail fold, and superficial onychomycosis begins in the superficial layers of the nail before progressing deeper.

It can be caused by Candida, a common pathogen, especially in immunocompromised individuals
A black finger nail fungus is a type of mycotic nail fungal infection. It causes the nail to turn black and can also make it thick, fragile, and separated from the nail bed. This type of infection can affect anyone, but individuals with diabetes, psoriasis, or athlete's foot are more likely to develop it. Additionally, older individuals, especially those over 70, are at a higher risk.
One particular cause of black finger nail fungus is Candida parapsilosis (C. parapsilosis), a common pathogen that often affects immunocompromised individuals. Candida parapsilosis can lead to greenish-black discolouration of the fingernail, along with recurrent onycholysis. Onycholysis refers to the separation of the nail from the nail bed, which is a common symptom of nail fungal infections.
Candida parapsilosis is a yeast-like organism that can cause paronychia, an inflammation that occurs at the base of the nail, leading to redness, swelling, and pain. It is often associated with injuries to the nail area, such as biting or picking at a hangnail, or from trimming or pushing back the cuticle. Paronychia can be treated by draining pus or fluid and sending it for laboratory analysis to determine the type of bacteria or fungus responsible. Warm water soaks, oral antibiotics, and, in severe cases, surgical intervention may be necessary.
To treat black finger nail fungus caused by Candida, oral antifungal medications are typically prescribed. For example, itraconazole has been used successfully to treat C. parapsilosis, with a regimen of 5 cycles of 200 mg twice daily for one week, followed by a 3-week interruption. It is important to consult a healthcare provider for proper diagnosis and treatment, as topical medications applied directly to the nail are usually ineffective for mycotic nail infections.
Preventing nail fungal infections involves proper nail care and hygiene practices. This includes washing hands and feet frequently with soap, ensuring you clean between the fingers and toes. It is important to avoid biting or picking at nails and to protect them from exposure to detergents and chemicals by using gloves. Trimming nails regularly after bathing, when they are softer, is also recommended.

The nail may thicken, become hard to trim, and separate from the nail bed
A fungal nail infection, also known as mycotic nails or onychomycosis, can cause the nail to thicken, become difficult to trim, and separate from the nail bed. This occurs when a fungus attacks a fingernail, toenail, or the skin under the nail, known as the nail bed. While anyone can get a fungal nail infection, certain factors increase the likelihood, such as having diabetes, psoriasis, or athlete's foot. Additionally, older adults, particularly those over 70, are more susceptible, with a 50% chance of developing a mycotic nail.
The nail thickening and separation from the nail bed are characteristic symptoms of mycotic nails. This condition is caused by a fungal infection, resulting in the nail becoming thick, fragile, and separated from the underlying nail bed. The nail may also exhibit colour changes, turning brown, white, or black.
The process of nail thickening in mycotic nails is associated with the overproduction of a protein-rich tissue called keratin. In the advanced stages of distal or proximal onychomycosis, a type of fungal nail infection, the nail can become extra thick and tall due to the excessive accumulation of keratin. This thickening can make trimming the nails challenging.
The separation of the nail from the nail bed is a notable feature of onychomycosis, specifically the type known as edonyx onychomycosis. In this condition, the interior of the nail plate is infected, while the nail bed itself remains unaffected. The nail may lift and separate from the nail bed, creating a space that can trap dirt and debris. Water ingress under the nail can further facilitate bacterial or yeast infections in this space.
It is important to note that fungal nail infections can progress and worsen without treatment. Therefore, seeking medical attention and receiving appropriate treatment are crucial to addressing mycotic nails and preventing potential complications.

Toenails are more susceptible to nail fungus than fingernails due to reduced blood flow
A fungal nail infection, or mycotic nail, occurs when a fungus attacks a fingernail, toenail, or the skin under the nail, known as the nail bed. The nail may turn brown, white, yellow, green, or black. It may thicken and become difficult to trim, and it may start to curl up or down or loosen from the nail bed. The nail could become brittle and crumble when touched.
Mycotic nails are caused by a variety of organisms, including dermatophytes, nondermatophyte molds, yeast, and various species of Epidermophyton, Microsporum, and Trichophyton. Fungi enter through small cracks in the keratin or the nearby skin and cause an infection. While anyone can get a mycotic nail, certain conditions increase the likelihood, including diabetes, psoriasis, and athlete's foot, a weakened immune system, blood circulation problems, nail injuries, and nail surgeries.
Treating a mycotic nail can be challenging. Topical medications applied directly to the nail are often ineffective in penetrating deep enough into the nail to cure the infection. Oral antifungal medications taken by mouth are more likely to be successful. Common oral antifungals include Griseofulvin (Fulvicin), Terbinafine (Lamisil), and Itraconazole (Sporanox). Treatment typically lasts six to twelve weeks for fingernails and twelve to thirteen weeks for toenails. In severe cases, the nail may need to be surgically removed to allow a healthy new one to grow in its place. Doctors can also use lasers or photodynamic therapy to treat nail fungus.

Treatment options include oral antifungals, topical medications, surgery, and laser therapy
A black fingernail could be a sign of a fungal nail infection, also known as onychomycosis. The infection causes the nail to become discoloured, thickened, and distorted. Toenails are more frequently affected than fingernails, and the nail may become thick, yellow, and brittle.
Treatment Options
Treatment options for severe or troublesome fungal nail infections include oral antifungals, topical medications, surgery, and laser therapy. For oral antifungals, medications such as terbinafine and itraconazole are commonly prescribed and are typically taken once or twice a day for several months. Antifungal tablets have many listed side effects and must be taken for extended periods, so they are not available over the counter. Topical treatments, such as antifungal nail paint, can also be applied directly to the nail. While this option doesn't usually cause side effects, it may be less effective than oral medication because it can struggle to reach the deeper layers of the nail.
In more severe cases, surgery may be an option, although the specific procedures that may be used are unclear. Laser therapy is another option for stubborn infections. This treatment uses high doses of light energy to destroy the fungus. However, it is not currently recommended as a routine treatment due to a lack of evidence, and it may need to be repeated for up to a year, making it an expensive choice.
