What You'll Learn

Application method
While there is no scientific evidence to support the claim that toothpaste helps nails grow, it may help improve their overall appearance.
To apply toothpaste to your nails, start by ensuring that the product does not contain any ingredients that may trigger skin inflammation or irritation. Read the label carefully, especially if you have underlying skin sensitivity or allergies.
Once you have confirmed that the toothpaste is safe for topical use, apply a generous amount to your entire nail, making sure to cover the surface evenly. Leave the toothpaste on your nails for around 10 to 15 minutes. You may then rinse it off under warm water using a toothbrush or nail brush to help eliminate any stains.
It is worth noting that vitamin E, in comparison with toothpaste, has been found to have more benefits for overall nail health. Additionally, while toothpaste may help improve the appearance of your nails, it is not a substitute for proper nail care and maintenance.

Myths and facts
Myth: Applying toothpaste to your nails will help them grow longer.
Fact: There is no scientific evidence to support the claim that toothpaste helps nails grow longer. While some people claim that applying toothpaste to your nails and letting it sit for a few minutes before wiping it off will help nails grow stronger and faster, experts do not recommend this method as there is a lack of research to support these claims.
Myth: Toothpaste can improve nail health and appearance.
Fact: While toothpaste may not promote nail growth, it can improve the overall appearance of your nails. Whitening toothpaste, especially those containing baking soda, can help whiten nails and eliminate surface stains. After removing your nail polish, apply a layer of toothpaste to your nails and let it sit for 10 to 15 minutes. Then, gently scrub your nails under warm water using a nail brush or toothbrush. This process can help brighten and whiten your nails, removing any stubborn residue or stains.
Myth: There are no effective ways to promote nail growth.
Fact: While there is no scientifically proven method to make nails grow faster, there are several home remedies and grooming techniques that can help. Maintaining good overall health and proper nutrition is essential for nail growth. A healthy diet rich in protein, calcium, vitamin D, iron, B-complex vitamins (including biotin), and antioxidants can promote stronger and healthier nails. Regular nail grooming, such as keeping your nails clean and dry, trimming them properly, and moisturizing your hands and nails, can also boost nail strength and reduce breakage.
Myth: Toothpaste is the only way to whiten nails.
Fact: While toothpaste can be effective in whitening nails, there are alternative methods to achieve the same results. Applying a base coat before painting your nails can help minimize staining. Additionally, vitamin E has been reported to treat nail discolouration and promote overall nail health. It is always important to read the ingredients of any product you apply to your nails to ensure they are safe and suitable for your skin type.

Alternative treatments
While there is no scientifically proven method for making nails grow faster, certain alternative treatments can help improve nail health and appearance.
Diet
Good nail health starts with a healthy diet. Nails are made of a hard protein called keratin, so consuming adequate protein is essential. A diet rich in calcium, vitamin D, iron, B-complex vitamins, biotin, and antioxidants is also beneficial for nail health. Several studies suggest that taking a biotin supplement daily can help strengthen nails.
Nail Care
Regular nail grooming and maintenance can help boost nail strength and encourage growth. This includes keeping nails clean and dry, trimming them straight across, and moisturising hands and nails with lotion, paying special attention to the cuticles. Avoiding nail biting and cutting nails too short is also important.
Nail Treatments
Over-the-counter and prescription nail strengtheners can be effective in promoting nail growth and strength. Ingredients to look for include vitamin E, calcium, green tea extract, and keratin or wheat protein. For example, Olive & June's Nail Strengthener contains plant-based ingredients like celery seed extract, which helps heal and condition the nail surface, reducing white marks and ridges.
Avoiding Harmful Chemicals
Many nail polishes and treatments contain harsh chemicals that can weaken nails. It is advisable to avoid nail polish removers with acetone and opt for nontoxic nail polishes and soaks. Hand sanitizers, shampoos for oily hair, and cleaning products can also dry out nails, so it is important to wear rubber gloves when cleaning or using such products.
Protecting Nails
Nails need to breathe, so it is recommended to take breaks between nail polish applications and avoid constant use, even with non-toxic polishes. Exposure to ultraviolet (UV) light during gel polish treatments is a risk factor for skin ageing and cancer, so sunscreen application on the hands before UV light exposure is advised.

Removing nail stains
While there is no scientific evidence that toothpaste helps nails grow, it can help improve their overall appearance. Whitening toothpaste, in particular, can help eliminate surface stains and brighten nails.
Toothpaste can be used to remove nail stains caused by nail polish, food, or other pigments and chemicals. It is important to note that this method may not completely remove intense stains, and there is a risk of skin irritation.
- Apply a small amount of whitening toothpaste to your nails.
- Let the toothpaste sit for 10 to 15 minutes.
- Using a nail brush or clean toothbrush, gently scrub the surface of your nails.
- Rinse the toothpaste off under warm water.
- Repeat this process two to three times a week for a month to treat persistent staining.
In addition to toothpaste, there are other ways to prevent and remove nail stains:
- Apply a protective base coat before using nail polish.
- Use a non-wipe top coat to repel stains.
- Avoid highly pigmented nail polish shades.
- Regularly change or remove nail polish, especially darker colours.
- Keep your nails moisturized with nail oil to reduce porosity and minimize staining.
- Avoid harsh chemicals like formaldehyde in your nail products.
- Gently scrub your nails with baking soda once or twice a week to keep them clean and bright.
- Opt for latex gloves when handling colourful spices or ingredients to prevent staining.
By following these tips, you can effectively remove nail stains and maintain healthy and stain-free nails.

Overall nail health
While there is no scientifically proven method for making nails grow faster, certain practices can help improve overall nail health and keep them strong and long.
Healthy nails are typically smooth, hard, and consistent in colour. To achieve this, it is important to maintain a healthy diet rich in protein, calcium, vitamin D, iron, B-complex vitamins, biotin, and antioxidants. Biotin, for instance, is a type of B vitamin that allows the body to turn food into energy and is highly recommended as a supplement to boost nail strength. Over-the-counter and prescription nail strengtheners with vitamin E may also be beneficial.
Additionally, regular nail grooming can help boost nail strength and reduce breakage. This includes keeping nails dry and clean, using sharp manicure scissors or clippers to trim nails straight and round off the tips, and moisturising hands and nails with lotion, especially at the cuticle area. Avoiding nail biting and ensuring you do not cut your nails too short are also important for nail health.
Nail health can also be an indicator of overall health. Discolouration and changes in texture may signal underlying health issues. For instance, white nails, known as leukonychia, could indicate trauma, anemia, dietary deficiencies, heart or kidney disease, or poisoning. Nails with a bluish tint may suggest insufficient oxygen in the body due to lung or heart problems. Rippled or pitted nails can be an early sign of psoriasis or inflammatory arthritis, while dry, brittle nails that crack or split may be linked to thyroid disease or a fungal infection. Therefore, while maintaining nail health through proper nutrition and grooming is important, it is also crucial to pay attention to any changes in your nails that could indicate a more serious health concern.
