Fill-ins, and so much more

Reshaping, shape correction and speed, all in one course.

The e-file scares you or slows you down

It's actually a gentle tool that makes daily work easier, as long as you know how to use it and understand what each bit is for.

Not fast enough in your daily work

You'll learn to spot the steps that waste your time, and the ones you can skip. Some students have cut their fill-in time in half.

Hooked nails, or a client who wants a new shape

A few techniques are all it takes to straighten a nail or change its shape at the fill-in, without adding a form and without wasting time.

Certificate and follow-up

You receive your certificate of completion at the end of the program.

You get one free correction if you need it.

Good to know

The course is done entirely in gel. If you work with acrygel or acrylic, it can still help you a lot.

This isn't a course on the shapes themselves: building square, coffin and almond (form placement, filing) is taught in Full Set Mastery.

Learning online, with someone checking your work

  1. Watch at your own pace

    Rewatch any lesson as many times as you need, something no in-person class allows.

  2. Send me your work

    Do a fill-in on a model or a client, then send me photos of the nails.

  3. Get your correction

    I point out what works and what to adjust. One correction is included.

It's for you if

  • You're already a trained nail technician

Hi, I'm Alicia

When I started in 2009, I spent three years making mistakes I couldn't explain. In 2012, a new training finally showed me that every one of them had a reason, and I started training others.

That's why understanding is at the heart of everything I teach. I've been training nail technicians since 2012 and online since 2020, and more than 23,000 nail technicians have joined the Kittycia community.
