01
What is it?
BIAB — Builder In A Bottle — is a thicker, stronger version of gel polish that adds a protective layer of structure directly onto your natural nails. Unlike regular gel, it's formulated to strengthen and support your nails as they grow, creating a tough yet flexible finish that moves naturally with your nail.
02
How long does it last?
BIAB typically lasts up to 3 weeks — longer than standard gel polish — making it one of our most low-maintenance nail treatments. Results will vary depending on nail growth rate, aftercare, and lifestyle.
03
Who is it for?
Ideal for anyone with weak, thin, or brittle nails, as well as nail biters or those who struggle to grow their natural nails. BIAB forms a strong, supportive shell that protects against breakage and splitting, helping your nails grow longer and healthier over time.
04
Maintenance
BIAB can be infilled as your natural nails grow, or soaked off with acetone and reapplied. When done correctly by a professional, it leaves your natural nails undamaged. We always recommend professional removal to protect your nail health.
05
Colours & extras
Available in a wide range of shades — from sheers and nudes to deeper tones — and can be used as a strengthening base with gel polish applied on top. Custom nail art and French finishes are available on request.
BIAB vs
Gel Polish
BIAB is thicker and more durable than standard gel polish, lasts significantly longer, and actively strengthens the nail rather than simply coating it with colour.
BIAB vs
Acrylics
Similar in strength but far gentler — no harsh chemicals, soaks off cleanly with acetone, and won't damage the natural nail bed. A great middle ground between gel and full extensions.
BIAB vs
Extensions
BIAB works with your natural nail rather than adding artificial length. It can add a small amount of natural-looking extension, but is primarily about protection and strength.
BIAB is particularly popular with clients who want the look of a professional manicure without the commitment of extensions — and whose nails need a little extra love.
