It's highly unlikely that fungus will directly spread from nail to nail via nail polish application because a bottle of polish isn't the most conducive environment for fungal growth due to all the chemicals present. However, while the risk is low, it's not zero either, so we would not recommend sharing nail polish!
Can Toenail Fungus Spread Through Non-Medicated Nail Polish? Fungus will be able to grow and stay alive in a bottle of nail polish. If you paint infected nails with non-medicated nail polish you can spread the infection. This happens when you paint a healthy nail after painting an infected nail with the same brush.
Any brush or nail file coming in contact with an infected nail should be immediately discarded to prevent transmission of the infection to other clients. If contact with an active nail infection were to occur accidentally, the nail polish should be discarded. — Doug Schoon is CND's chief scientific advisor.
The danger with keeping your nail polish on too long is that the pigment in the nail polish can soak into the top few layers of the nail and dry it out, Dr. Rowland says. When that happens, fungus, yeast, bacteria, mold and mildew can develop underneath the nail plate, which can lead to long-term problems.
Our golden rule is one week on, one week off, at the absolute most. Any more, and you're basically preparing breeding grounds for nail fungi.
Without treatment, toenail fungus almost always worsens, and can lead to permanent nail damage. In severe cases, toenail fungus can progress and cause widespread infection of the foot. A serious infection of these unwanted microorganisms can even cause nerve damage in the affected area.
A pharmacist can help with fungal nail infections
nail-softening cream – it's used for 2 weeks to soften the nail so the infected part can be scraped off.
ClearZal Nail Care Solution is a topical solution for infected nails that kills bacteria and fungus on contact. Use twice daily for safe and effective treatment of your thick or discolored nails.
Your health care provider may prescribe an antifungal nail polish called ciclopirox (Penlac). You paint it on your infected nails and surrounding skin once a day. After seven days, you wipe the piled-on layers clean with alcohol and begin fresh applications.
Effective products include efinaconazole (Jublia), tavaborole (Kerydin) and ciclopirox (Penlac). All require daily applications, and it may take as long as a year to see noticeable improvement. These products may work for early, superficial fungal infections because they kill fungi on the surface of the nail.
Two independent scientific studies confirm that nail polish products do not harbour microbes, so it is not likely that any pathogen could be spread to cause infections. Water-based cosmetic products typically contain preservatives to prevent microbial contamination, when they are sold in multi-use packages.
Vicks Vaporub softens and lightens toenails. This makes it look like the fungus is being treated. Vicks may have some antifungal qualities, but it is unable to penetrate the toenail well enough to cure the infection. Many topical antifungal medications have this issue.
“Applying Vicks VapoRub to fungus-infected toenails can clear up the notoriously hard-to-treat condition. Michigan State University clinicians found that applying the product daily to the infected nail cleared the condition in 32 of 85 patients, though it took anywhere from 5 to 16 months…”
If you just finished treating nail fungus, throw away shoes, boots, skates, and other footwear that you wore before you started treatment. Fungus can live in footwear, giving you another infection. If your footwear is expensive or new, you can disinfect them using an ultraviolet (UV) shoe sanitizer or ozone cabinet.
The wound should heal within a few weeks. Fingernails may take 6 months to grow back. Toenails may take 12 to 18 months to grow back.
After nail removal, the wound can become infected. You can reduce the risk of infection by keeping the area clean. The fungal infection may not be killed and may infect the new nail that grows.
When used topically, tea tree oil is believed to be antibacterial. Tea tree oil is commonly used to treat acne, athlete's foot, lice, nail fungus and insect bites.
If toenail fungus is left untreated, it can spread to the surrounding skin on the foot, causing another condition known as athlete's foot. An athlete's foot is a condition resulting in itchy, red, and cracked skin, which can become very uncomfortable.
A severe case of nail fungus can be painful and may cause permanent damage to your nails. And it may lead to other serious infections that spread beyond your feet if you have a suppressed immune system due to medication, diabetes or other conditions.
There are several risk factors for developing nail fungus: tight shoes; damaged nails; walking barefoot in moist areas like swimming pools, saunas, and public showers; poor blood circulation in your legs; a weakened immune system; and other skin conditions, such as psoriasis.
If the treatment is working, you should see a new healthy nail start to grow from the base of nail over the course of a few months. The old infected nail should begin to grow out and can be gradually clipped away. Antifungal treatments are thought to be effective in treating about 60 to 80% of fungal nail infections.
Taking antifungal pills for two months can cure an infection under the fingernails. Usually three months of treatment cures a toenail fungal infection. Antifungal pills, however, can cause side effects. Your dermatologist will watch you closely.
