Your mani may not be the most pressing thing on your mind these days. But if you haven’t been to a nail salon in a few weeks (or months), you will likely come to a point where your gel nails require maintenance that only a pro can offer. Aside from visible regrowth not looking quite as fresh or polished as you’d like, letting gel polish grow too far can strain the health of your nails, leaving them frail and damaged (due to weight imbalance and lifted, jagged edges).
