CHOOSE YOUR SIDE OF THE CHAIR

— FOR CLIENTS

Want hair that just
works?

Hair extensions, cuts and colour on the Gold Coast, in a private home salon. One client at a time. No rushing, no chaos. Just hair you love, done by someone with over a decade behind the chair.

— FOR STYLISTS

Ready to go solo,
or upskill?

Online hair extension courses, a go-solo eBook, and in-person training across Australia. Built for stylists ready to specialise, charge properly, and work hours that actually fit their life.

WHY SPECIALISE IN EXTENSIONS

Most hairdressers end up fully booked, with capped earning potential. Most stylists know it. Most just accept it.

There’s another version of this career, and it’s the one I’ve spent the last decade building. Specialising in hair extensions and running my own business means working fewer days and earning more.

It’s not magic. It’s pricing, positioning, and a skill set most generalist stylists never learn. The courses below are how I teach it.

And how specialising in extensions changes the maths

OUR FOUNDER

Hi, I’m Maddy

I’m a Gold Coast hair extension specialist and the educator behind beauty lab gc. Over a decade in, I’ve worked the salon floor, run the chair, and learned — the hard way — what actually works and when you go out on your own.

These days I split my time between the chair and the classroom. Real clients, every week. Real students, learning the actual job. Both make me better at what I do.
