Yellow Nails: Cause, cure and prevention
By Brid McNulty, August 8 2022
Just as it sounds, yellow nails syndrome is a condition whereby your nails become a pale yellow colour. This can signify many underlying issues – from something as simple as nail polish staining to more serious health conditions. We’ll outline some of the main causes and cures of yellow nails syndrome in this article. Of course, it’d be best if we never got yellow nails in the first place, so we’ll go through some prevention tips too.
Bacterial infection or fungus
Yellowing nails is commonly due to a nail infection or fungus. Nasty, we know, but it happens! Other symptoms of a fungal infection can include flaking of the nail and an unpleasant odour. If left untreated, the nail bed could retract, causing it to thicken and crumble.
Curing Yellow Nails of Infection or Fungus
The best idea is to get yourself to a dermatologist – not urgently but if after 10-14 days of at-home remedies, you haven’t seen any improvement then make an appointment. Not only will they properly diagnose you and treat your needs better, but prescriptions are far more effective than OTC treatments for yellow nails. Be aware that prescriptions will take weeks to months to fully bring your nails back to full health. Your healthy nail needs time to grow and replace the old yellowed nails.
Before you run to the dermatologist, try some of these at-home remedies:
- Oregano Oil: It’s been found to have antimicrobial properties. If you’re unsure as to whether the yellowing is from bacteria or fungi, oregano oil is ideal as it treats both. Apply it to affected nails by mixing it with a carrier oil such as olive, coconut or jojoba oil. We highly recommend Zane Hellas Oregano Oil Softgels as an easy way to get the oil into your diet.
- Tea Tree Oil: Another easy treatment you can try, and effective too – studies show that tea tree oil can stop common strains of nail fungus from growing. Just mix 1-2 drops of tea tree oil with a carrier oil and swab on the discoloured nail. Try MAYJAM tea tree essential oil to help clear up fungal nail infections.
- Baking Soda: Another common household product and an anti-fungal treatment. As fungus only grows in acidic environments, baking soda’s alkaline pH prevents the fungus from spreading. Soak your feet or toes in hot water mixed with baking soda will do the trick. After a few soaks, you should see your nails clearing up.
Preventing Bacterial or Fungal Infections on Nails
There are nail hygiene steps you can take to prevent nail infections.
- Make sure to trim your nails often and keep dirt out from underneath the nails.
- Wear fresh socks, and let your feet free to avoid toenail infections like athlete’s foot.
- Don’t use nail polish remover more than once a week on your nails.
- Nail salons can spread infections too through the use of unsanitized tools. Make sure your nail technician uses a clean or new kit.
Stained from Nail Polish
Removing weeks or months worth of polish can often result in an unsightly yellowish stain on your nails. Darker polishes tend to do the most harm, leaving nails stained with leftover dyes. Not the end of the world though!
Curing Stained Nails
Probably the best home remedy in the book: lemon juice. Soak your nails for 10-15 minutes daily in lemon juice until the stains have disappeared. Or, if you think your polish stains are just immediate, e.g. you’ve just removed yellow polish and see superficial stains, try whitening toothpaste. Scrub your nails with toothpaste using a nail brush. This should do the trick.
Another at-home hack is baking soda and peroxide. Simply mix 2.5 tablespoons of baking soda and 1 tablespoon of hydrogen peroxide in a bowl. It’ll come to a pasty consistency. Using a cotton ball, cover your entire fingernail with the paste. Rinse after it’s been on for about 3 minutes. Repeat this treatment every 6-8 weeks. And do make sure to rinse thoroughly and rehydrate your hands and nails with lotion and cuticle oil afterwards.
In most cases from staining, the discolouration is only on the top layer of the nail bed. The solution can be as simple as a few rounds of buffing. Sometimes, the yellowing can make its way to your cuticles too. At this point, it’s probably best just to get a professional manicure – they’ll know how to get your nails back in tip-top shape.
Prevent Stained Nails
Prevent stained nails by investing in a clear base coat. It will protect your nails from staining, plus it extends the lifespan of your pretty mani/pedi. Nailberry’s Strengthen and Breathe Base Coat is a firm favourite of ours. A dual-action, vegan and non-toxic base coat that doesn’t break the bank!
Another anti-yellowing tip – apply a high-quality nail oil containing jojoba or squalene on a daily basis. For a cruelty-free, high quality oil, try Cliganic Jojoba Oil. It may be that your nail beds are very porous, and easily absorb the dyes from nail polishes – unlucky! In this case, we’d recommend not leaving your polish on for too long (no more than a week), and opting for lighter colours. Or, stick with acrylics – they don’t stain your nails.
Smoking Yellows Your Nails
As if smoking doesn’t come with a large enough list of negative health effects, well, here’s another: yellow nails. The tar and nicotine from cigarettes is the culprit. The cure? Stop smoking. Prevention? Don’t start smoking. We know it’s harsh, but it’s just the truth on this one.
More Serious Health Issues
A change in the colour of your nails can also be a sign of something more serious. Thyroid, liver and lung diseases, amongst other conditions like diabetes, can all lead to yellowing nails. If after 10-14 days of at-home treatments, you don’t see any improvement go see your doctor. They will be able to test whether the yellow nails are due to fungus, yeast, bacteria, or something more serious.
Vitamin E to cure AND prevent yellow nails
Taking a healthy dose of Vitamin E will help cells retain moisture and look healthier. This affects not just your nails but your skin and hair too. More importantly, Vitamin E is clinically proven to be an effective treatment for yellow nails. One more tip – Vitamin E stimulates nail growth. Speed up healthy nail growth with either a topical or oral application of Vitamin E – so you can grow out your yellowed nails with healthy, vital nails.
If you are in the market for a great, affordable vitamin E cuticle oil, we recommend Sally Hansen Vitamin E Nail & Cuticle Oil.
