Scrub toothpaste onto nails for 3-5 minutes
While there is no scientific evidence to support the claim that toothpaste promotes nail growth, some people believe that scrubbing toothpaste onto nails for 3-5 minutes can help achieve brighter, stronger, and breakage-proof nails.
To do this, simply squeeze out some toothpaste and use your fingers or a toothbrush to scrub it onto your nails for 3 to 5 minutes. You can use whitening toothpaste, which contains hydrogen peroxide, to eliminate stains and whiten your nails. If you use a toothbrush, you can add a small amount of fine pumice or baking soda to create a mild abrasive that will smooth out your nails.
After scrubbing, leave the toothpaste on your nails overnight for the best results. In the morning, wash it off and apply a moisturiser.
While this method may not actually promote nail growth, it may help improve the overall appearance of your nails.

Wash off toothpaste and apply moisturiser
After you've scrubbed toothpaste onto your nails for 3-5 minutes, it's important to let it sit overnight for the best results. In the morning, wash off the toothpaste with warm water. You can use a toothbrush or a nail brush to help eliminate any stains. Make sure to read the label of the toothpaste to ensure that the ingredients won't cause skin inflammation or irritation, especially if you have sensitive skin or allergies.
After washing off the toothpaste, it's essential to apply a moisturiser to your nails and cuticles. This can be in the form of a hydrating hand cream or cuticle oil. Keeping your nails and the surrounding skin hydrated will help to improve their strength and overall appearance.
You can also try massaging your nails and cuticles with an electric toothbrush and a small amount of Vaseline. This will help to improve the health of your cuticles and encourage blood flow to the area. Additionally, you can add a mild abrasive like fine pumice or baking soda to the toothbrush to speed up the process and smooth out your nails.
While there is limited scientific evidence to support the claim that toothpaste promotes nail growth, it may help improve the overall appearance of your nails. Toothpaste, especially whitening toothpaste, can help to eliminate surface stains and whiten nails. The hydrogen peroxide found in whitening toothpaste has a recognised bleaching effect.

Read toothpaste labels to avoid skin irritation
While there is no scientific evidence to support the claim that toothpaste helps nails grow or become stronger, some people believe that it may help improve their overall appearance. For instance, whitening toothpaste may help to eliminate surface stains and remove stubborn nail polish residue.
However, it is important to carefully read the labels on toothpaste tubes to avoid skin irritation. Some people, especially those with underlying skin sensitivity or allergies, may experience skin inflammation or irritation from certain ingredients commonly found in toothpaste.
One such ingredient is sodium lauryl sulphate (SLS), a common detergent and surfactant present in toothpaste. SLS promotes the formation of lather and may have some antimicrobial effects. However, as a detergent, it can cause irritant contact dermatitis, especially on the perioral skin. SLS may also increase the frequency of aphthous ulcers, also known as canker sores, and exacerbate their occurrence or severity due to its potential to disrupt the delicate oral mucosa, leading to tissue irritation and inflammation.
Individuals with sensitive skin or a history of allergic reactions may benefit from choosing SLS-free toothpaste to reduce the risk of irritation and other side effects. These side effects may include oral irritation, dry mouth, a burning sensation in the mouth, and allergic reactions.
Therefore, when considering using toothpaste on your nails, it is crucial to read the labels and choose a product that is unlikely to cause skin irritation, especially if you have sensitive skin or allergies.

Use whitening toothpaste to remove nail stains
While there is no scientific evidence that toothpaste promotes nail growth, it can certainly improve their overall appearance.
Whitening toothpaste can be used to remove nail stains and eliminate surface discolouration. First, remove any nail polish with a nail polish remover. Then, apply a thick layer of whitening toothpaste to your nails, ensuring that you cover the entire nail. Allow the toothpaste to sit for 10 to 15 minutes. Once the time is up, grab a nail brush or toothbrush and gently scrub your nails under warm water for 1-2 minutes. Rinse your hands with warm water until all the toothpaste is removed. Repeat this process for several days if you are dealing with a severe case of staining.
Toothpaste can be an effective and inexpensive option to brighten your nails and make them look beautiful. It is thought that the natural whitening properties of baking soda in toothpaste can help to remove stains from nails, just like it does for teeth.
It is important to note that you should always read the ingredients of the toothpaste carefully to ensure that they will not trigger any skin inflammation or irritation. If you have sensitive skin or allergies, it may be best to opt for a friendlier alternative, such as topical vitamin E, which has many benefits for overall nail health.
