Accredited course | Case studies required | E-file qualification included
Take your extension skills to the next level with our Advanced Sculpted Extensions Course, designed to build your confidence in creating strong, beautifully structured extensions using ACRYGEL and SCULPT & BOOST Hard Gel.
During this practical, hands-on course, you’ll work with both paper forms and sandwich forms, learning how to achieve the correct fit, build strength and structure, and refine your extensions for a clean, professional finish.

You’ll also work with bottled and potted Hard Gel, as well as learning when and how to incorporate Builder Gel or Hard Gel over a sculpted extension.
Ideal for qualified nail techs who already have a foundation in gel services and want to develop their skills in more advanced sculpting and extension techniques.

Why We Teach E-File
E-file techniques are essential for modern nail professionals. At TWENTY, we believe in working smarter, not harder.
The E-file allows for:
-
More efficient and thorough nail prep
-
Smoother product application
-
Reduced strain on your hands and wrists
-
Quicker, safer removals
-
Better retention through precise refinement
Learning how to use the E-file properly means you can cut down on appointment times, increase bookings, and ultimately boost your income—without sacrificing quality.

This is an accredited course, and upon completion you’ll be required to submit two case studies demonstrating your understanding and execution of SCULPT & BOOST builder gel services. Once approved by your educator, you’ll receive your official Hard Gel Certificate, allowing you to offer these services professionally and confidently.

What Makes This Course Different?
We believe that confidence and competence come from real experience. That’s why your learning journey doesn’t end in the classroom.
To complete the course, you’ll be required to submit two case studies—real-life client sets that demonstrate your understanding, technique, and professionalism.
Your educator will review your work in detail, offering personalised feedback to fine-tune your application process and ensure your results are safe, consistent, and salon-ready.
Why Case Studies?
Because confidence comes from doing—not just watching.
Working on real clients (friends or family) without an educator over your shoulder is your opportunity to prove to yourself that you’re ready. And with your educator's guidance, you’ll have the expert support to perfect your skills before you ever open your appointment book.
Once your case studies are approved, you’ll receive your fully accredited certificate, qualifying you as a professional nail technician.
Why In-Person Training Matters
While online courses offer flexibility and convenience, nothing compares to the quality, depth, and hands-on confidence you gain from in-person training—especially when you're learning a technical, practical skill like nail application.
Here’s why our in-person training makes all the difference:
1. Learn By Doing — Not Just Watching
Watching videos can teach theory, but real confidence comes from physically practising the techniques under expert guidance. You’ll be working with real products, on real hands, in real time—so you can refine your skills through action, not guesswork.
2. Instant, Personalised Feedback
With in-person training, your educator is right there to correct, adjust, and guide you every step of the way. This level of live, tailored feedback is something you simply can’t get from pre-recorded content.
3. Spot & Correct Bad Habits Early
Without supervision, it’s easy to develop incorrect techniques that can lead to lifting, client complaints, or even damage to the natural nail. In-person training allows us to spot those mistakes early—and fix them on the spot—before they become bad habits.
4. Build Confidence in a Real-World Setting
Our classroom environment is designed to mimic salon scenarios, giving you the chance to practise services in realistic conditions. You’ll gain experience managing timing, product control, and client communication in a way that prepares you for real paying clients.
5. Human Support = More Motivation
Learning can feel lonely online. In-person, you're surrounded by fellow students, a supportive educator, and a buzz of encouragement. You can ask questions, get reassurance, and stay motivated from start to finish.
6. You're Not Just Learning—You're Being Assessed
We hold our students to professional industry standards. That means you’re not just ‘ticking boxes’—you’re being coached, assessed, and supported until your skills meet the standard required to succeed in real life.
The TWENTY Standard
At TWENTY, we believe that nail training should be more than just passable—it should be exceptional. That’s why our in-person courses are immersive, detailed, and backed by industry-leading educators who care about your success.
Because when you’re working with real clients, real products, and real responsibility…
