What is a 'fill' at a nail salon?

At Iris Avenue nail salon in Central London, a “fill” (what we call an infill) is a maintenance appointment designed to refresh and extend your existing builder gel, BIAB, hard gelm or acrylic nails without removing the entire set.
When your natural nails grow, a small gap appears between your cuticle and the product applied during your original manicure. During a fill appointment, your nail technician carefully prepares the regrowth area, rebalances the structure, and applies new gel or builder product to blend seamlessly with your existing manicure — restoring strength, shape, and shine.
Why You Need a Fill
To maintain nail health: Fills prevent lifting or breakage as your nails grow.
To keep nails looking perfect: Your colour, shape, and finish stay flawless between full sets.
To save time and money: Instead of a full removal and reapplication, you refresh only what’s grown out.
Most clients book their nail salon fill every 2–3 weeks, depending on how quickly their nails grow and how well they care for them at home.
🩰 The Fill Process at Iris Avenue
Gentle preparation: We file and buff the existing gel or BIAB layer to smooth the transition between old and new growth.
Cuticle care: Any excess skin or lifting is gently removed for a clean, polished base.
Rebalancing: Fresh builder gel or product is applied to restore the nail’s shape and strength.
Finishing touches: Choose a new colour, nail art, or classic top coat — it’s the perfect opportunity for a seasonal refresh.
How to Know When You Need a Fill
If you notice visible growth near the cuticle, slight lifting, or uneven balance, it’s time to schedule a nail fill appointment.Keeping a consistent maintenance schedule helps your nails stay strong and prevents premature chipping.
