Hard BIAB™ - The Collection

Bold strength. Beautiful length. Bottled.

The new generation of BIAB™ has arrived with The Hard BIAB™ Collection — Brought to you from the brand that started it all.

Designed for longer nails and heavy-handed clients, this advanced formula combines the strength of a hard gel with the effortless application of our best-selling BIAB™ formulas. Whether you're sculpting extensions or reinforcing long natural nails, Hard BIAB™ delivers exceptional durability, flawless control, and a self-levelling finish — all in one bottle.

With a thicker viscosity for precision shaping and file-off formula built to last 4+ weeks, it's the ultimate solution for nail overlays, infills, nail fixes and extensions. Proudly made in the UK and HEMA & TPO-free, this hard builder gel collection includes 10 colour-matched BIAB™ icons plus two must-have shades - Bonnie and Skye.

For the most consistent, long-lasting results across all clients, we recommend pairing Hard BIAB™ with Rubber Base or Bond Base as standard practice. 

File-off system. Compatible with all TGB Base Coats for optimised adhesion and easier removals.
