About this course
Master structure, overlay and extension
Take your gel work further with builder‑in‑a‑bottle (BIAB) systems. You'll learn correct structure and overlay technique, extension work, and how to build strength and shape without compromising nail health, taught in a small group so you get real one‑to‑one feedback.
A live model is included on the day, so you leave with confidence applying the technique on a real client, not just a practice hand. This course suits technicians who already have core gel polish experience.
