Ragged and brittle nails are the reality for many who suffer from an all-too-common habit: nail-biting. The truth is, bitten nails are a common problem and one we'd all like to rectify if we had some expert advice.

One way to make bitten nails stronger? Fake nails, which act as something of a shield while your real nails grow and strengthen. Even better for those of us with a habit of constantly biting our nails, fake nails offer a way to avoid and, well, break the practice entirely.

For more about how to combat the dreaded after-effects of nail-biting (and to learn why we all bite our nails in the first place), we turned to a few experts.

Read on to learn if fake nails can help stop your nail-biting habit once and for all.

Why Do We Bite Our Nails?

More often than not, nail-biting is a symptom of stress or anxiety and a habit that affects nearly everyone at some point in their lives. But for some, it can be more severe than others.

"It’s a type of body-focused repetitive behavior," says Dr. Sanam Hafeez. "There’s a range of nail-biting. It can span from an occasional behavior to a self-mutilative behavior."

While it can become a lifelong habit for some, for most, it's a habit that's easy to outgrow.

"For most, it's a way to release tension and provide soothing, similar to how children are soothed by sucking their thumbs. Hand to mouth behavior an outgrowth of the desire for oral satisfaction, with nursing being the earliest form. Some women play with their hair for similar soothing results," says Vivian Diller, PhD.

Can Fake Nails Help Prevent Nail Biting?

Fake nails not only hide your own bitten nails, but they make it increasingly difficult to bite, acting as something of a (literal) mask over the problem.

"If there’s an artificial nail on top of your natural nail, this makes it more difficult to bite your natural nail," says Grant.

"Like with any habit, substituting it with another activity or changing the behavior can help break the cycle. When women wear fake nails, it creates a temporary interference with nail-biting behavior," says Diller.

Despite the temptation to have long, luxurious digits, it is best to start off having very short nails—probably just to the ends of your fingertips. A long nail extension adds weight and could tear the underlying and especially weak nail away from the bed and cause long-term damage.

How Long to Wear Fake Nails to Stop Nail Biting

Generally speaking, it's best not to wear any particular set of nails for longer than three or four weeks. "I think getting a new set repeatedly can help with biting, and one can see an improvement on their natural nail within a month if they’re taking care of the nails underneath the fake nails," Grant says.

It takes the natural nail anywhere from three to six months to grow from the cuticle (the bit nearest your hand) to the tip of your finger. During that time, you will have to have what are known as "fill-ins" to cover the gap at the base of your nail when the growth begins. Initially, it will be quite rapid, so expect to have your first fill in within about two weeks of the set of nails being put on. After that, it will slow down a little bit. When the nails come off, use a strengthener like OPI Natural Nail Strengthener ($11) and make sure to file them regularly to maintain shape.

As Diller explains, waiting for the natural nail to grow beneath the fake nails is the best way to ensure you break your nail-biting habit. "It usually takes about 90 days to change most habits (and keep the new one), but it depends on how long-standing the habit is," adds Diller.

Choose fake nails in a bright color, like red or orange, as an added alert to not bite your nails.

When and How to Remove Fake Nails

If you decide that nail tips are not for you, or if you are ready to have them removed to reveal your natural nails, make sure that the job is done professionally. If you try to do it yourself, all of your hard work will likely be undone because the nail underneath will be particularly soft and could tear off. This will take some time to heal, as nails need to grow out to become longer and healthier.

According to Grant, how you remove a fake nail depends on what type of nail it is. Here's the down-low on removing the most frequently-used types of nails.

  • Press-on nails applied with sticky tabs: "Saturate the cuticle in oil. Then take an orangewood stick and carefully place it between your natural nail and press on nail. Gently push until the press-on nail is off," explains Grant.
  • Press-on nails applied with nail glue: "Soak your nails in an acetone-based remover until some of the glue breaks down and the nails become loose. Then take an orangewood stick and gently push until the nail is removed," Grant says.
  • Acrylic nails: Cut down the length of the nail, then file down the top of the nail—this helps the acetone. Then soak your nails in pure acetone for a few minutes until the acrylic begins to dissolve. Then use a metal pusher to push some of the product back. Repeat this process until your nails are bare. Then, grab a buffer to get any of the excess bits off," Grant says.
  • Gel extensions: "The process is very similar to acrylic. Cut down the length of the nail, then file the polish down a bit as this helps the acetone to remove it faster. Then soak your nails in pure acetone for a few minutes, grab a metal pusher and push some of the product down. Repeat until nails are bare," advises Grant.

How to Care For Your Natural Nails 

Keeping your nails healthy will help to manage a nail-biting habit. "If you trim your nails or get a manicure and keep the cuticles moisturized, it might be less tempting to pick/bite, and you might even begin to take pride in their appearance as opposed to trying to hide them," says Hafeez.

Also key to healthy nails: moisture. "Cuticle oil is key here. Moisturized cuticles are destined to grow," says Grant. "If it’s hard for you to keep up with them during the day, always put cuticle oil or balm on them before you go to sleep," Grant says. She also suggests pushing back your cuticles. "Regularly pushing back (no cutting!) your cuticles back also helps make room for new nail growth."

The Takeaway

Hopefully, by the time your natural nails are a reasonable length, you will have been cured of the nail-biting habit. The nail will not be strong, though, possibly not for some years, depending on how long you were a biter.

Be patient and be prepared to use lots of nail strengthening products to assist your nails in the process, even after your fake nails are off.

"I do think a couple of good gel manicures or whatever your preference of fake nail is can make an improvement on the urge to bite," says Grant.
