BIAB Infills: How Often to Book and Why Not to Soak Off Every Time

A BIAB infill refreshes your builder gel manicure by filing back the existing product and filling the regrowth gap at the cuticle, rather than removing everything. Most clients book an infill every three to four weeks. Because your natural nail is not soaked and filed bare each time, infills are one of the gentlest ways to keep nails strong and growing.

What happens at an infill appointment

• Your technician checks each nail for lifting or damage.
• The top layer and some of the old product are filed back, leaving a thin, well-bonded base.
• Cuticles are tidied and the regrowth area is prepared.
• Fresh builder gel is applied to rebalance the nail, then your colour and top coat.

How often should you book?

Every three to four weeks suits most people. Leave it much longer and the nail’s balance point moves forward as it grows, which makes breaks and lifting more likely. If your nails grow quickly, or you prefer a longer shape, three weeks is usually best.

Infill or full removal?

An infill is right while the existing BIAB is well bonded. A full soak-off is better if there is significant lifting, if you want a complete change of length or shape, or if you are taking a break from builder gel. Your technician will advise at each visit. Never peel product off yourself: our guide on why you should never peel off gel explains why.

Why infills help your natural nails

Repeated full removals mean more soaking and filing on the natural nail. Infills keep a protective layer in place while your own nails grow underneath, which is why so many of our clients use BIAB to grow out weak or bitten nails.

Frequently asked questions

How often should I get a BIAB infill?

Every three to four weeks for most people. Fast-growing or longer nails often benefit from three weeks.

Can I get an infill if my BIAB was done at another salon?

Usually yes, if the existing product is well bonded. Your technician will check and recommend a full removal if it is not.

Is an infill better for my nails than a removal?

Generally yes, because the natural nail is not soaked and filed bare at every appointment.

Can I change colour at an infill?

Yes. The colour layer is renewed at every infill, so you can switch shades each time.
