Discover the Surprising Reason Behind Your Yellowing Nails
When you look at your hands and notice your nails have taken on a yellow hue, it can be quite alarming. However, there are several reasons this might happen, and understanding them can help you address the issue effectively.
Dr. Shereene Idriss, a board-certified dermatologist based in New York City, explains that nails are more porous than many people realize. This characteristic allows pigments from nail polish, especially darker shades, to be absorbed, leading to a yellowish tint. “The iron oxides in those polishes become oxidized and result in the temporary yellow-rust like color that will eventually resolve,” she notes.
To prevent this type of staining, Dr. Idriss advises using a clear base coat before applying deeply pigmented polishes. Additionally, she suggests removing nail polish after about a week and occasionally allowing your nails to go polish-free.
Another potential cause of yellow nails is fungal infections, particularly if you frequently use public showers without wearing protective footwear. “There’s definitely a fungus among us, especially when walking barefoot in the locker room,” Dr. Idriss warns. Fungal infections can turn nails yellow-green and make them brittle. If you suspect a fungal infection, consulting a dermatologist is crucial, as treatment varies based on the infection’s source.
Beyond cosmetic reasons, yellow nails can also indicate more serious health issues. Dr. Idriss mentions that chronic lung disease, poor liver function, and smoking can lead to nail discoloration. “Certain vitamin deficiencies such as B-12 and zinc can also lead to nail discoloration over time,” she adds.
In rare cases, yellow nails may be a sign of “yellow-nail syndrome,” a hereditary condition associated with middle age. This syndrome not only affects nails but also causes leg swelling and respiratory issues. “Treating the underlying lung issues and leg swelling is of crucial importance to your health,” Dr. Idriss advises, though she notes that nail color may not revert due to genetic factors.
Dr. Marisa Garshick, another board-certified dermatologist, emphasizes the importance of identifying the cause of yellow nails to determine the appropriate treatment. For polish-induced discoloration, she recommends avoiding dark colors and allowing nails to breathe. Nail brighteners containing ingredients like vitamin E and lemon extract can also help.
For fungal infections, antifungal treatments are essential. In contrast, managing yellow nail syndrome involves addressing associated symptoms rather than the nail discoloration itself.
Diet can play a role in maintaining nail health. Dr. Garshick suggests incorporating foods rich in vitamin E, such as avocado and almonds, into your diet. Regular moisturization and minimizing nail trauma can also prevent yellowing.
While home remedies like vinegar soaks may help with mild infections, persistent issues should be evaluated by a healthcare professional. If home treatments are ineffective, it’s important to consult a doctor promptly.
