What You'll Learn
Smoking
The degree of staining may vary depending on the depth of puffs taken, which can result in higher tar deposition on the skin. Smoking fingertips and nails, also known as "smoker's hands", are not a direct health concern. However, they may indicate long-term smoking or the use of unfiltered tobacco, both of which elevate the risk of various smoking-related side effects and diseases.
In addition to cosmetic concerns, smoking can lead to several health complications in the hands and fingers. These include premature ageing, delayed wound healing, increased susceptibility to infections and inflammatory skin conditions, and vascular changes that reduce blood flow. In severe cases, the reduced blood flow may even necessitate finger amputations.
The yellow staining caused by smoking can be removed using household remedies such as lemon juice, baking soda, or nail polish remover. However, it is important to note that nail polish remover can be harsh on the skin and nails, so frequent use should be avoided. Completely quitting smoking or switching to tobacco products without tar, such as snus, can also prevent and resolve discolouration issues.

Nail polish
Yellow nails can be caused by a variety of factors, including nail polish. While nail polish is often a cosmetic choice, it can contribute to nail discolouration, especially if used frequently or in darker shades. The dye in nail polish interacts with the keratin in the nail, causing yellowing and potential brittleness. This effect can be exacerbated by the use of acetone-based nail polish removers, which can dry out and damage nails, making them more susceptible to staining.
To prevent nail discolouration from nail polish, it is recommended to reduce the frequency of polish application and opt for lighter shades. Additionally, using a protective base coat can create a barrier between the nail and the coloured polish, reducing the likelihood of staining. Taking breaks from nail polish and allowing nails to breathe can also help prevent discolouration.
If your nails have already turned yellow due to nail polish, there are several remedies you can try. Soaking your nails in diluted vinegar (one part vinegar to four parts water) can help reduce the yellowing. Another option is to soak your nails in lemon juice for 10–15 minutes, followed by gentle scrubbing with a soft nail brush. Alternatively, you can create a mixture of hydrogen peroxide and baking soda and apply it to your nails with a cotton swab until the stain disappears.
While nail polish can be a contributing factor to yellow nails, it is important to consider other potential causes as well. Yellow nails can sometimes indicate an underlying health condition, such as a fungal infection, yeast or bacterial infection, or a more serious ailment. If you are concerned about the colour of your nails, it is always best to consult a healthcare professional or a dermatologist, especially if the discolouration persists or is accompanied by other symptoms.

Fungal infections
Yellow nails are often caused by staining from nail polish, self-tanner, or smoking. However, they can also be a sign of a fungal infection or a more serious underlying health condition.
Fungal nail infections are a common cause of yellow nails. They can be treated with topical medications or prescription medications. Over-the-counter antifungal nail treatments containing tea tree oil or oregano oil are a popular first option. Tea tree oil has been shown to effectively stop common strains of nail fungus from growing. However, it is important to consult a healthcare provider if home remedies are not effective in eliminating nail discoloration. Oral antifungals such as terbinafine (Lamisil) or itraconazole (Sporanox) can be prescribed, but they may have side effects and are not recommended for long-term use. Ciclopirox (Penlac Nail Lacquer) is another alternative prescription treatment that is applied directly to the nail.
It is important to note that no oral or topical antifungal treatment is 100% effective, and recurrence of nail fungus is common. Therefore, maintaining good nail hygiene is crucial to preventing nail discoloration.
If you suspect a fungal infection, it is advisable to see a dermatologist for proper diagnosis and treatment. While yellow nails can sometimes be resolved with home remedies, they can also indicate a more serious underlying health issue.

Health conditions
Yellow nails can be a sign of various health conditions. One of the most common causes of yellow nails is a fungal infection. This can be treated with antifungal medications, laser therapy, or nail removal. Other symptoms of a fungal infection include flaking of the nail, an unpleasant odour, and thickening and deformity of the nail plate. If left untreated, the nail bed could retract, thicken, and crumble.
Another possible cause of yellow nails is yeast or bacterial infections. This can be treated with oral prescriptions such as terbinafine (Lamisil) or itraconazole (Sporanox). Ciclopirox (Penlac Nail Lacquer) is an alternative prescription treatment that is applied to the nail like nail polish.
Yellow nails can also be a symptom of more serious health conditions, including chronic lung conditions, internal malignancies, lymphatic obstructions, and rheumatoid arthritis. Additionally, yellow nails can be a sign of thyroid disease, liver disease, lung disease, or diabetes. In the case of diabetes, around 40% of people with the condition experience a yellow tint to their nails, although the reasons for this are unclear.
If you are concerned about yellow nails, it is best to consult a board-certified dermatologist, as nail changes can sometimes indicate underlying health problems.

Self-tanner
If you suspect that your self-tanner is causing your nails to turn yellow, you can take some preventative measures. One way to prevent staining is to wear gloves when applying self-tanner. You should also wash your hands thoroughly after applying self-tanner to remove any excess product. Additionally, you can apply a small amount of Vaseline to your nails before applying self-tanner to create a barrier and protect your nails from staining.
If your nails are already stained, there are some home remedies you can try to remove the self-tanner. One method is to use a cloth to rub vinegar onto your nails, which should remove the staining. You can also try soaking your nails in a bowl of water with a denture tablet for about 10 minutes. Alternatively, you can use a cloth or cotton ball soaked in lemon juice or nail polish remover to wipe away the discolouration.
While self-tanner can be a cause of yellow nails, it is important to consider other possible causes, such as nail polish, fungal infections, or underlying health conditions. If you are concerned about the discolouration of your nails, it is recommended to consult a healthcare professional.
