The use of Vaseline for nail growth is actually unfounded, and even for those who struggle to grow their nails, using Vaseline is not a solution. What petroleum jelly does to your fingernails and cuticles is to lock in moisture (via Fabbon) and to make them stronger and less likely to break, per My Glamm.
Method: Step 1: Wash your hands and apply vaseline over your entire nails. Step 2: Rub it for at least 3-5 minutes and let it absorb completely. For best results, keep it on overnight and wash it off the next morning.
Make sure to avoid getting any Vaseline on your actual nails, however, because it will inhibit the polish from sticking and drying. In the case you have any rogue petroleum jelly on your nails, grab another cotton swab dipped in either nail polish remover, water, or vinegar and clean up the edges before polishing.
Rub a small amount of petroleum jelly into your cuticle and the skin surrounding your nails every evening before you go to bed or whenever your nails feel dry.
"Trimming your nails does not promote nail growth but it is important to keep them at a comfortable length if you are prone to ingrown nails since they could cause trauma and lead to slower nail growth," Bank said. Regular trims can also keep your nails nice and healthy.
Before you start painting, line your cuticles with a Q-tip dipped in Vaseline to prevent polish from sticking, as beauty guru Michelle Phan demonstrates on her blog. The Vaseline creates a barrier between your nail and skin so you can wipe away mistakes when you're finished.
'Preliminary studies suggest that consuming gelatin can improve the hair,' they report. The same study shows that eating gelatine also makes nails stronger and less brittle.
What is petroleum jelly made of? Petroleum jelly (also called petrolatum) is a mixture of mineral oils and waxes, which form a semisolid jelly-like substance. This product hasn't changed much since Robert Augustus Chesebrough discovered it in 1859.
It might protect your hair against breakage and dryness, but it won't encourage your hair to grow at a faster rate. Some people also warn against applying Vaseline to your scalp or face, claiming that it can create a breeding ground for bacteria or even block hair follicles.

Take biotin
Biotin is an important type of B vitamin that allows the body to turn food into energy. It's also highly recommended as a supplement to help boost the strength of hair and nails. Several human studies suggest that taking a biotin supplement daily can help strengthen nails.
Why Won't My Toenails Grow? For leg hair and toenails to grow, you need proper circulation in your legs and feet. Unfortunately, arterial blockages can cause numerous symptoms including poor toenail growth. The lack of oxygen and nutrients to the nails can cause them to grow very slowly, or stop growing entirely.
Your fingernails grow slowly — in fact, they grow about one tenth of an inch (2.5 millimeters) each month. At that rate it can take about 3 to 6 months to completely replace a nail. Where your nail meets your skin is your cuticle. Cuticles help to protect the new nail as it grows out from the nail root.
