This is especially beneficial for those who experience dry, brittle nails due to daily activities such as washing, detergent use, or dry climates. The application of petroleum jelly can result in stronger, healthier nails that are less likely to break or chip. Some individuals have also noticed accelerated nail growth and improved nail appearance after incorporating petroleum jelly into their nail care routine. The product is affordable, easily accessible, and can be used in combination with other products, such as cuticle oils, to enhance its nourishing effects.

What You'll Learn

Petroleum jelly is an occlusive moisturiser
Petroleum jelly is a byproduct of the petroleum (oil) industry. It is an occlusive moisturiser that does not get absorbed into the skin or nails but creates a protective barrier to seal in moisture.
When used on the nails, it can help protect and preserve nail growth by preventing moisture loss. This is because the jelly forms a barrier on the nails, preventing them from becoming dehydrated and brittle. This makes the nails less likely to break, chip, or split, allowing them to grow longer and stronger.
The process of using petroleum jelly on the nails is known as "nail slugging". It involves applying a thick layer of petroleum jelly or any occlusive ointment to the nails and cuticles for an extended period. This helps to combat damaged, over-processed, or dry, brittle nails.
To perform nail slugging, start by exfoliating the nails and cuticles. Then, apply a cuticle oil or moisturiser to your cuticles. Finally, seal in the product with a generous amount of petroleum jelly. This will lock in moisture and provide a protective barrier to prevent further moisture loss.
Some people have reported noticeable improvements in their nail growth and condition after using petroleum jelly. However, it is important to note that petroleum jelly does not directly make nails grow faster. Instead, it helps to protect and preserve the nail growth you already have by keeping the nails and cuticles hydrated and healthy.

It seals in moisture
Petroleum jelly, such as Vaseline, is an occlusive moisturiser that seals in moisture. It cannot soak into nails, but it can help protect and preserve the nail growth you already have by preventing moisture loss.
Daily activities can cause wear and tear on nails, dehydrating them. Repeated washing and drying of fingernails, dry climates, winter months, detergents, and soaps can strip nails of their moisture, making them dry and brittle. This makes nails more likely to break and chip.
Applying petroleum jelly to your nails can prevent this moisture loss by sealing in the cuticle oil so that it will penetrate deeper and provide a protective barrier. This is a process known as "nail slugging", which is the nail version of skin slugging.
To slug your nails, first exfoliate, then apply a product with real nail and cuticle-hydrating and strengthening benefits, such as a cuticle oil. Then, seal in the product with an occlusive like Vaseline. This can be done as often as you want, and you can even put Vaseline on your nails every night if they are exceptionally dry.

It can protect and preserve nail growth
While there is no scientific evidence that petroleum jelly can make nails grow faster, it can certainly help protect and preserve nail growth.
Daily activities can cause wear and tear on nails, making them dehydrated and brittle. This can lead to nails that are more prone to breaking and chipping. As an inexpensive and simple product, petroleum jelly can be an effective solution to keep nails and the skin on your hands healthy.
Petroleum jelly is an occlusive moisturiser that seals in moisture. It can be used to lock in the effects of a moisturiser or cuticle oil, creating a protective barrier to prevent moisture loss. This is often referred to as "nail slugging", which is a popular method to combat dry, brittle, and damaged nails.
By keeping your cuticles and nails hydrated, petroleum jelly helps to preserve nail growth by reducing the likelihood of breakage and chipping. This protective barrier helps to prevent external factors, such as water, moisture, and organisms, from entering the nail unit and causing issues such as redness, swelling, and infections.
Additionally, the application of petroleum jelly can improve the overall appearance of your nails, making them look stronger, healthier, and with a natural sheen.

It can be used in nail slugging
Petroleum jelly can be used in nail slugging, a process that has gained popularity on TikTok, to help heal, moisturise, and strengthen nails. Nail slugging is the "nail version of skin slugging", where petroleum jelly or any occlusive thick ointment is applied to the nail and cuticle for an extended period. This helps to combat damaged, over-processed, dry, and brittle nails.
To slug your nails, first exfoliate your nails and cuticles, just as you would with your skin. Then, apply a product with nail and cuticle-hydrating and strengthening benefits, such as a cuticle oil. You can use any cuticle oil, but LeChat Nails educator, Anastasia Totty, recommends one with vitamin E, as it is great for moisturising and softening the skin and treating inflammation. After applying the cuticle oil, seal in the product with an occlusive, such as Vaseline, to lock in and protect the hydrator. This occlusive layer will help to prevent moisture loss and provide a protective barrier.
Nail slugging can be done as often as you want, and it is a great way to give your cuticles some extra TLC. It is a simple and inexpensive way to help improve the health and appearance of your nails, making them stronger, healthier, and less likely to break and chip.
