Gel Extensions- Refilling
A gel extensions refill, also known as a gel fill, is a nail treatment that involves applying new gel to the grown-out portion of gel nail extensions:
As your natural nails grow, the gel extensions move away from your cuticles. A gel fill involves removing the grown-out portion of the gel, prepping your nails, and applying a new coat of gel.
Gel fills help keep your nails strong and allow them to grow longer. They also prevent you from over-prepping your natural nails, which can weaken them.
You should get a gel fill when your nails start to look unaesthetic or the gel extensions show signs of yielding. This is usually after about 3–4 weeks, but it can vary depending on how fast your nails grow and how well you care for them at home.
