Have you ever wondered why your toe nails sometimes turn green or yellow?

You’re not alone. The human toenail is a tough beast and can take quite a beating. It’s also not uncommon for toenails to look discolored, thick or deformed.

Greenish toenails are most often the result of a bacterial infection, but they can also be caused by an underlying medical condition. Sometimes, if your body lacks nutrients, your nails may turn yellow.

A greenish discoloration of the nails is usually caused by an infection with Pseudomonas bacteria. This type of bacteria is found in damp places like showers and swimming pools, and is often transmitted inside shoes.

Have you ever noticed a discoloration in your toenails? Maybe you saw a green nail or yellow nail, and wondered what was going on.

The discoloration of your nails could mean nothing—or it could mean that you have an infection.

But if your nails are turning green or yellow, you’re not alone. A lot of people have this problem, and there are things you can do to fix it.

Why Do Toenails Turn Green or Yellow?

Toenails turn green or yellow when they are infected with fungus. This is the same fungus that causes athlete’s foot. The fungus is all around us—it’s everywhere in the environment—but it flourishes most in warm, moist places like locker rooms and other public places where people go barefoot. If you get the fungus on your feet, it can be spread to your toenails by scratching them with dirty hands.

The problem with toenails turning green or yellow is a common one. If you’ve worn nail polish for a long time, have worn your shoes and socks too tight, or have sweat a lot in your shoes, you may have developed this issue. The good news is that there are many ways to get rid of the discoloration.

How Do Nails Turn Green?

Toenails can turn green for different reasons. Sometimes it’s because you’re wearing tight-fitting shoes or socks, but it can also be due to the type of nail polish you use. Sweating profusely in your shoes can also cause your nails to turn green.

The most common reason that toenails turn green is because of something called keratin granulation. Keratin is the protein that makes up your nails and hair, and it builds up as dead skin cells underneath your nails or on top of them. This buildup looks like tiny dots and can make your toes look dirty and green, even if they’re not. Keratosis pilaris is another condition that causes thickening of the nails and can make them appear yellowish or greenish.

It is not unusual for toenails to turn a yellowish, greenish, or brown color. This discoloration is caused by the pigment melanin and can be the result of a number of different factors. Rather than something that indicates a serious health problem, it usually points to an issue with hygiene or nail care. A variety of problems can cause this discoloration, but luckily there are also a number of treatment options that can help restore your nails to their natural color.


If you have noticed that your nails have turned yellow or green in color, your parents might be to blame. In most cases it is the result of genetics and is harmless. The only thing you can do about it is paint over them with polish or remove them completely. If you are going to polish your nails you should consider using a base coat before applying polish.


Melanoma is one possible cause for green and yellow fingernails. Melanoma occurs when pigmented cells grow out of control, causing dark growths on the skin and nails. Although rare, it should always be checked out by a doctor because if left untreated melanoma can spread to other organs within the body and become cancerous. If you notice any dark spots or

Many people have experienced it: You’re chilling in your favorite sandals, your toes painted with a fresh coat of vibrant polish. But after a few days, one or more of your toenails transform from a pretty pink color to a grotesque shade of green.

What gives? Why do toenails turn green? The short answer is that fungi and bacteria love the dark, warm, moist environment that sweaty socks and closed-toe shoes provide. These microorganisms can latch onto your nails and slowly cause them to change colors.

But getting rid of the fungus is another story. Treating green toenails isn’t always easy — especially when topical medications fail to work after weeks or even months of use.

In this post, we will explore why you may have developed green toenails. We will also discuss how you can treat the problem using natural remedies and home care tips.

Did you know that your toenail color can tell you a lot about your health? For example, if your toenails or fingernails are yellow, they are probably healthy. If they are green or blue, then there is probably a problem. Green and blue nails may be caused by too much nail polish. Sometimes too much of the same polish, such as white or yellow, can cause your nails to turn green or blue. The best way to avoid this is to use different shades of nail polish each time.

If you have green or blue toenails, you should see a doctor right away. These colors mean that you have an infection. Your doctor can help you get better.

A common infection in the toenail is called onychomycosis (on-ee-ko-my-ko-sis). This is when a fungus (an organism that causes disease) grows in the skin and nails. The fungus usually grows under the nail and makes it thick and hard for air to get into it. Sometimes it makes the nail turn brown, yellow, white, or black. When this happens, it’s called “onycholysis” (on-ee-ko-ly-sis). The best

Toenail fungus may not be the most pressing health issue you’ve ever dealt with, but it can be downright embarrassing. No one wants to wear sandals or walk around barefoot with toenails that are yellow or green.

Toenail fungus is a common condition that begins as a white or yellow spot under the tip of your toenail. As the fungal infection goes deeper, nail fungus may cause your nail to discolor, thicken and crumble at the edge. It can affect several nails but usually not all of them.

If your condition is mild and not bothering you, you may not need treatment. If your nail fungus is painful and has caused thickened nails, self-care steps and medications may help. But even if treatment is successful, nail fungus often comes back.

The tendency for nails to become thicker and prone to infection increases with age, so older adults are at greater risk for nail fungus than younger people are. Men are more likely than women to have nail fungus, but toenails are more likely than fingernails to be infected because they’re often confined in dark, warm places where fungi grow well (such as shoes), and they’re exposed to trauma (such as stubbing) that breaks down their
