Acrylics can be something of a lifesaver for those who have a bad habit of biting their nails or who just can't seem to keep their own nails naturally long. But staying on top of them and ensuring that they always look their best is a priority if you want to take advantage of them. wearing acrylic nails also requires some commitment on your part - a bi-weekly commitment, to be exact. Every two weeks, you'll need to go back to the salon and have your nails refilled to enjoy those acrylics in their best possible state.
