Soak nails in diluted hydrogen peroxide
Soaking your nails in diluted hydrogen peroxide is a common method for treating nail discolouration and restoring whiteness. It is also used to treat toenail fungus, which can cause yellowing and discolouration of the nails.
To prepare the solution, pour the desired amount of hydrogen peroxide into a clean container. Typically, a 3% concentration of hydrogen peroxide is recommended, as higher concentrations can cause skin irritation. Then, add water to the solution. A common dilution ratio is one part hydrogen peroxide to one part water, but you can use less water for a more potent solution. It is important to consider your skin sensitivity and the severity of the discolouration or infection when determining the ratio.
Before applying the solution to your nails, it is recommended to perform a patch test on a small area of skin to ensure you do not experience any adverse reactions. Wait a few minutes to check for any redness, itching, or irritation.
Once you have confirmed that the solution is safe for your skin, you can proceed with the soaking process. Fill a small basin or container with the diluted hydrogen peroxide solution, ensuring that there is enough to cover the affected nails completely. Soak your nails in the solution for the recommended duration, which can range from 2 minutes to up to 30 minutes.
After soaking your nails, gently buff or scrub the surface of your nails with a soft toothbrush. Finally, rinse your nails with water. This process can be repeated 2-3 times per week as needed until you achieve the desired level of whiteness.

Apply a whitening toothpaste to nails
If your nails have turned yellow due to nail polish, you can use whitening toothpaste to restore them to their former brightness. Whitening toothpaste that contains hydrogen peroxide and baking soda is the most effective.
First, remove any nail polish you may have on your nails with nail polish remover. Then, apply a thick layer of whitening toothpaste to each of your nails. You can use a toothbrush to scrub the toothpaste onto your nails. Leave the toothpaste on for 10 to 15 minutes.
Once the timer goes off, grab a toothbrush and scrub your nails under warm water. Rinse off the toothpaste with warm water to reveal brighter, whiter nails. If you did not achieve your desired results, you can repeat the process. You can also apply hand cream after this treatment to add moisture back to your skin.

Create a paste with lemon juice and baking soda
Lemon and baking soda are two common household ingredients that can help whiten your nails. This mixture is a great cleanser and can give your nails a clean, healthy appearance.
To create a paste with lemon juice and baking soda, start by mixing one tablespoon (15 mL) of lemon juice with two tablespoons (30 mL) of baking soda in a small bowl. Stir the mixture until it forms a thick paste. If the paste looks too runny or doesn't stay on your nails, add more baking soda until you achieve the desired consistency.
Once you have your paste, use a cotton swab or a soft toothbrush to apply it to your nails. Make sure to cover the top of your nails and the area underneath the tips. Let the paste sit on your nails for about 10 minutes.
After the waiting period, rinse your hands with warm water and mild soap to remove the paste. Be sure to gently scrub your nails to ensure all the paste is removed.
Finally, apply a hand cream or cuticle oil to your nails and cuticles to add moisture back to your skin. Lemon and baking soda can be drying, so it's important to moisturize after this treatment.
You can repeat this treatment once or twice a week until your nails are white.

Soak nails in white vinegar
Soaking your nails in white vinegar is an effective way to make them white again. It is a simple, natural treatment that can be done at home. White vinegar is a great option for those seeking to regain shiny and strong nails, as it disinfects and adds shine, especially to brittle nails.
To perform this treatment, prepare a soaking bath with pure white vinegar. You can also use cider vinegar if you want to disinfect your nails at the same time. The process is simple: just soak your nails in the vinegar for about 5 minutes.
If you want to enhance the effects of the vinegar, you can create a more complex solution by adding other household products. One option is to combine equal parts of white vinegar and water, along with a few tablespoons of lemon juice, in a bowl. Soak your nails in this mixture for up to 15 minutes to effectively bleach them.
Another powerful mixture involves creating a homemade salt soak. Combine half a cup of baking soda, half a cup of Epsom salt, a quarter cup of hydrogen peroxide, a quarter cup of white vinegar, and four cups of hot water in a glass bowl. Soak your nails in this solution for 10 minutes, then rinse them with clean water and apply hand cream.
In addition to its whitening properties, white vinegar is also beneficial for those prone to infections or fungal infections. The acidity of cider vinegar helps rebalance the skin's pH while eliminating fungi and bacteria. It is also a great ingredient to stimulate nail growth.

Consult a doctor for underlying conditions
While nail discolouration is usually not a serious condition, it is important to consult a doctor to rule out any underlying issues. Nails are a window into your overall health, and changes in colour, such as black stripes, can indicate severe underlying medical conditions.
If you are unsure about the cause of your black nails, it is recommended to seek medical advice. Your doctor may perform a nail biopsy to examine for any signs of infection or disease. This is especially important if you suspect you have melanoma, a type of skin cancer, as early detection makes it much easier to treat effectively. Melanoma can present as brown or black streaks under the nail that may grow over time.
Additionally, black stripes on the nails could be a sign of linear melanonychia, which is common among African Americans. This condition occurs when melanocytes, the pigments in the nail, produce excess pigment, causing the nail beds to darken. Less common but more serious causes of black stripes include certain medications, chemotherapy drugs, or underlying diseases such as lupus, scleroderma, or HIV.
If your black nails are accompanied by other symptoms such as thickening, accumulation of debris under the nail, or pain, it could indicate a fungal infection. Onychomycosis is the most common nail infection, affecting approximately 2% to 14% of people in the United States. Consult your doctor for proper diagnosis and treatment. They may recommend antifungal medications or other interventions to address the infection and improve the appearance of your nails.
In summary, while there are many at-home treatments for whitening nails, it is important to consult a doctor if these methods do not work, as discoloured nails may indicate underlying health issues.
