How to Know If My Nails Need A Fill?

Acrylic nails provide a long-lasting, well-shaped manicure that lasts at least two months. What about fills, though? You need to know the signs that indicates you need to get your nails filled.

One of the most frequent inquiries we get from new customers is whether they need their acrylic nails removed and replaced every time they come in.

No, that’s not the case. You can simply have an infill!

During infilling, it is normal to file off the current color and eliminate any lifting. This process also takes a brief check at the nail to ensure no germs or diseases are present. You have the option of changing the form of the nail or shortening it.

Now comes the matter of how you’ll know you got nails that need a fill. What are the telltale signs? How many times do you think you’ll be able to employ this technique? With these concerns in mind, I conducted some studies on the subject and would want to share my results with you today.


What Are Infills on Acrylic Nails?

Following the application of acrylics, you will observe spontaneous regrowth of your fingernails after 2 to 3 weeks. It’s hardly the prettiest look, but regular trips to the manicure salon aren’t the most cost-effective option.

Infills can save the day when it comes to maintaining your nails that need a fill since they conceal the visible natural nail and effectively “top up” the existing manicure. They operate by injecting additional acrylic into the gaps, allowing you to paint the entire nail again and extend the appearance.

Signs That Your Acrylic Nails Need a Fill

When should I come back for a nail infill? Is one of the most often requested questions? Is it really two weeks? Is it really three weeks? or even five weeks? If you return after two weeks, some individuals will charge you extra. This technique does not sit well with me.

For instance, some people require an infill every two weeks as their nails grow too quickly or they have “chronic lifting”. Personally, I believe that you should only enter when you believe it’s essential or when the indications are present.

If it’s been two, three, four, or even five weeks. They only need to take a peek. Examine for new growth, lifting, and if they’re growing too long. The nail grows about 3mm every month on average. Certain actions, as well as internal and external situations, have an impact on growth.

Nails grow faster:

  • during the day
  • on young age (between 30 to 50 years)
  • in the summer, UV rays have an impact
  • pregnant woman
  • genetic

In any case, you must determine when your nails require an infill. You need a refill:

  • If your new growing region is sufficiently large
  • If the stress point has shifted too much, the nail will become weak and imbalanced
  • If you bite nails and have lifting issues
  • If you have to do a lot of lifting because of an injury
  • If your fingernails are starting to “pain” or feel uncomfortable
  • when you’ve had enough of your current design and want to try something fresh

So, no one can accurately predict when someone will require an infill. In most cases, however, an infill is required between 2 to 5 weeks.


How to Fill Acrylic Nails

How to Fill Acrylic Nails

Filling acrylic nails isn’t as hard as it seems. You can do it at home too if you have the proper knowledge. So, why wait? Let’s see the process so that you can fill your nails anytime you want!

  • Smooth the extra acrylic using a nail buffer. Brush the rough end of the acrylic layer where it touches your natural nail with a buffer. Buff the upper surface of your nail until it’s completely smooth. Make sure you’re simply smoothing the acrylic, not the actual nail.
  • Apply one to three applications of nail primer to your nails. Apply 1 drop of nail primer to the natural portion of your nail with a brush. Allow for complete drying before applying one to two more layers, if needed. The preparation will protect your nail while also allowing the polish to glide on more easily.
  • On the head of a brush, mix the acrylic powder with liquid acrylic. Fill one tiny dish with acrylic liquid and the other with acrylic powder. Soak an acrylic nail applicator in the liquid and gently dab it into the powdered acrylic. Rep 4–5 times more until a bead of the mixture develops on the brush’s end. This combination may be used to fill your nails.
  • The acrylic mixture should be applied to the natural section of your fingernails. Dip the end of an acrylic soft bristle brush into the mixture, leaving 1 drop on the brush. Place a drop of the mixture in the center of your original nail and tap it equally across it with the brush. Fill in the edges and along the cuticle using the brush’s sides.
  • Allow your filled nails to dry naturally. It might take anywhere between 5 and 20 minutes for nails to dry completely. While your nails are curing, try not to smudge them.
  • Make sure your nails are smooth by buffing or filing them. Flatten and reshape the ends of your nails with a nail buffer. You may also buff the periphery of your nails to make them smooth if desired.
  • Paint the nails with 1 to 3 layers of paint. Before applying the nail paint, apply a base layer to the acrylic nails and let them dry fully.

How Many Infills Can You Get on Acrylic Nails?

Acrylic Nails can have infilled for an unlimited period of time. To put it another way, you can have as many nail refills as you like, and it’s generally done every two weeks.

If you want to retain your acrylic nails for three, four, or more months, keep a close eye on your original nail below them for any greenish traces or other signs of fungus. Hyperpigmentation of your original nail, inexplicable thickness, or extremely dry cuticles around your nails is all signs of nail fungus.

Acrylics, no matter how excellent they are, can induce fungus and then disguise it! Too much moisture accumulates between the fake nail and your real nail if acrylic nails are left on for too long. Bacteria may grow when they have nowhere to hide!



To summarize, you have the option of filling in your nails as many times as you like. A refill should be done every two weeks at the most, and you don’t need to see your nail technician more frequently than that. An acrylic set generally lasts 6 to 8 weeks before it needs to be replaced.

You can obtain an unlimited number of refills if you skip the new set. In the meanwhile, look after your nails and make absolutely sure there are no symptoms of cuticle infections, fungus, or inflammations. Take a careful look at your nails and check them thoroughly every now and again.
