BIAB Nails in Putney.

BIAB stands for Builder in a Bottle. It’s a premium, high-strength builder gel. We use it to reinforce, protect, and overlay your natural nails. Unlike traditional, thin gel polishes, BIAB possesses a unique flexibility and structural density. This allows it to absorb daily impact, preventing your natural nails from bending, snapping, or chipping.

It is the gold standard for individuals looking to cultivate long, healthy natural nails, and serves as an exceptional structural support system for nail biters looking to break the cycle.

BIAB is much thicker and more durable than regular gel. Think of gel as paint, while BIAB is like a reinforcing layer that adds structural strength. That’s why it prevents breakage and lasts 2-3 weeks without chipping.

Yes, BIAB is widely considered the healthiest nail option at a premium salon for long-term care. Because it is highly durable, it eliminates the need for frequent, aggressive removal processes. At Le Lotus, our technicians often perform “BIAB infills” rather than complete removals, protecting your natural nail plate from the constant scraping and acetone exposure associated with standard gel or acrylics.

Yes! BIAB is perfect for both. For weak nails, it acts as a protective shield letting them grow. For nail-biters, the finish is so hard you physically can’t bite through it, helping you break the habit while your natural nails recover underneath.

BIAB typically lasts beautifully for up to 3 weeks without lifting or chipping. Hard gel can technically last slightly longer because it is completely rigid and non-porous (it cannot be soaked off with acetone). However, BIAB’s unique flexibility actually makes it more comfortable for daily wear on natural nails, as it moves with your nail rather than fighting against it.

No! When applied and removed properly by a trained technician, BIAB actually improves nail health. It protects your nails and prevents breaks, allowing them to grow strong. It’s much gentler than acrylics.

BIAB is a dense, high-performance gel. As a result, it can sometimes create a brief ‘heat spike’ under the LED lamp. However, this only happens if your natural nail is severely damaged or thin. Our artisan technicians mitigate this entirely by using low-heat settings and precise, thin layering. Additionally, BIAB requires professional removal or maintenance every 3 to 4 weeks; attempting to peel it off at home will damage the natural nail.
