I’ve had Cezanne smoothing treatments before, so I thought I knew exactly what to expect.
The deep cleanse. The blow-dry. The application. The waiting. And then the marathon flat-ironing session that seals everything into the hair and leaves it impossibly smooth for months.
But when I recently visited Brush Salon in Vancouver to see master stylist Roberto Sousa, he introduced me to a small—but surprisingly significant—twist on the traditional Cezanne process. And after seeing the results, I’m convinced it’s the way the treatment should be done.
Like any Cezanne appointment, the service began with an ultra-thorough cleansing. My hair was shampooed multiple times until it was completely free of product buildup, oils and residue, creating the perfect canvas for the treatment. After a meticulous blow-dry, Roberto carefully applied the Cezanne formula section by section before allowing it to process for about 30 minutes.
That’s where things took an unexpected turn.
Instead of leading me back to the sink to rinse out the solution—as most salons do—Roberto reached for a fine-tooth comb.
Working methodically through my hair, he “squeegeed” the excess product out, one tiny section at a time, gently removing only what wasn’t needed while intentionally leaving far more of the treatment inside the hair shaft.
It’s one of those techniques that makes immediate sense once it’s explained.
The true magic of Cezanne doesn’t happen while the treatment sits on your hair. It happens during the painstaking flat-ironing stage that follows. As each tiny section passes through the iron again and again, heat activates the treatment, creating the smoothing effect Cezanne has become famous for. The more treatment that remains in the hair before this step, the more product is available to participate in that chemical reaction.
In other words, why rinse away something you’re about to activate?
It’s a simple shift in technique, but one rooted in understanding the chemistry behind the service rather than simply following a standard protocol.
Then came the longest—and arguably most important—part of the appointment.
Roberto patiently flat-ironed impossibly small sections of hair with incredible precision. If you’ve ever had a smoothing treatment, you know this isn’t the glamorous part. It’s repetitive, meticulous work that requires both patience and experience. But it’s also where the transformation happens.
The payoff was immediate.
My hair looked noticeably smoother than previous Cezanne treatments I’ve had. Better still, it retained movement. Unlike some smoothing systems that can leave hair looking unnaturally flat, my hair still had body—it was simply free of the frizz and puffiness that humidity inevitably brings.
What impressed me most, though, wasn’t just the result. It was Roberto’s willingness to refine an already excellent service.
The best stylists don’t simply follow instructions—they understand why those instructions exist and look for thoughtful ways to elevate the experience. His decision to remove excess product by “squeegeeing” rather than rinsing wasn’t about reinventing Cezanne; it was about maximizing its performance.
It’s exactly the kind of detail most clients would never notice, but one that can make all the difference.
For anyone considering a smoothing treatment this summer—or anyone who’s been disappointed by inconsistent results in the past—it’s proof that the technician matters just as much as the treatment itself.
Sometimes, the biggest beauty breakthroughs come from the smallest changes. And in this case, one less trip to the shampoo bowl may have made all the difference. —Noa Nichol
