It’s generally a good idea to keep your nails short for press-ons. Here are a few reasons why:
Better Adhesion: Shorter nails provide a larger, flat surface area for the press-on nails to adhere to, which can help them stay on longer.
Comfort: Short nails can make it easier to apply the press-ons and ensure they fit well without being uncomfortable.
Durability: Press-ons can be more prone to lifting or coming off if applied over long natural nails, especially if they experience any bending or impact.
Appearance: Short natural nails underneath the press-ons can give a more natural and seamless look.
That said, you don’t have to cut your nails extremely short—just ensure they’re trimmed and filed so the press-ons can adhere properly and feel comfortable.
