Imagine being able to offer clients smoother, more manageable hair that feels effortless—no matter the forecast. Now it’s possible with Wella Professionals SmoothFiller.
Hair texture has always been—and continues to be—a top concern for most clients. Everyone wants smooth, polished hair without the extra effort. They’re looking for solutions that help them style faster, enjoy sleekness longer, and keep finished looks touchable even when the humidity hits. That’s where NEW Wella Professionals SmoothFiller steps in.
SmoothFiller is a new, demi-permanent approach to smoothing. Designed to work with the hair, it delivers smoother texture, reduced frizz, and easier styling that lasts up to 3 months, all in a pleasant and fast* salon experience.
New SmoothFiller: Effortless hair, every day.
SmoothFiller was created to deliver effortless hair, every day. This salon-exclusive service adds just one product to your menu, yet delivers noticeable results. With use, you’ll notice hair that feels smoother, looks more polished, and is easier to style, all without sacrificing natural movement. Meaning you get smooth results without the usual trade-offs.
Speaking with Wella Professionals Global Color Ambassador Nikki Lee, it’s clear why SmoothFiller feels like such a revolutionary step forward. It delivers that smoother, frizz-free, more manageable finish clients want—without the heaviness or long-term commitment that can come with traditional smoothing. As Lee puts it, “SmoothFiller is redefining what a smoothing service can be a true breakthrough that delivers smoother, frizz-free more manageable hair. My clients and I are obsessed with it.”
What Is SmoothFiller?
SmoothFiller is a demi-permanent smoothing service created specifically for clients who want better hair texture without committing to traditional straightening treatments.
It’s an ideal treatment for naturally frizzy hair, those with strands that are difficult to manage, or anyone who’s style is usually impacted by humidity. It is perfect for clients who blow-dry often as this helps them achieve a smooth finish in less time.
What You’ll Love About SmoothFiller:
- Smoother hair
- Reduced frizz
- Easier and faster styling
- Results that last up to 3 months
And because the smoothing effect gradually fades over time, hair naturally returns to its original texture without any visible regrowth.
What Causes Hair to Frizz?
Frizz can show up for different reasons—your natural hair texture and porosity, daily habits, or the environment—but it often comes down to the hair’s outer layer becoming less smooth. When the cuticle lifts, hair can take on moisture unevenly in humid air, swell in some areas more than others, and lose that sleek, polished finish. Dryness, heat or chemical stress, friction from rough towel-drying, and even hot water or overwashing can all contribute to frizzy hair.
How SmoothFiller Works
SmoothFiller helps combat frizz from the inside out. Using a Smart Delivery System, the active ingredient penetrates deep into the hair cortex rather than forming an artificial coating on the surface. Then, through thermal activation, it fills the hair’s protein structure and creates new, stable, longer-lasting bonds that help restructure the hair internally. The result is hair that feels smoother, is easier to style, and keeps natural movement with reduced frizz for up to 3 months.
A Pleasant and Fast¹ In-Salon Experience
SmoothFiller was designed with both the stylist and the client in mind. It’s a salon-exclusive service that takes under two hours, with a streamlined process that fits easily into any schedule. It’s a one-step formula with only 8 carefully chosen ingredients, and offers a low-fume experience throughout the service. There are also no post-service restrictions. Meaning clients can wash their hair, work out, swim, or put their hair up the very same day.
How SmoothFiller Stands Out
SmoothFiller fills a clear gap in the smoothing category. While many clients are seeking smoother texture and frizz reduction, there are a lot of concerns around chemical ingredients, long procedures, and restrictive aftercare.
But with SmoothFiller, there’s no waiting period, no sweating restrictions, no requirement for sulfate-free shampoo, and no unpleasant odors during the service. It doesn’t contain keratin or protein—instead, it creates a new kind of bond inside the hair that lasts up to 3 months.
Even better, SmoothFiller can be performed on the same day as color services, whether you’re covering greys, glossing, lightening, or doing it all.
All of the Upsides. None of the Downsides.
Only one product is needed, with no additional rinsing required after heat activation. And because the hair gradually reverts back to its natural texture over time, it’s an approachable, flexible option for a wide range of clients.
The Upsides:
This on-trend service is easy to apply, can be done on the same day as hair color, is done in under 2-hours and allows your client to wash the hair immediately.
None of the Downsides:
With only one product, this uncomplicated service with low odor/fumes makes it easy to add to your service menu and even easier to take care of at home with simple aftercare.

The Perfect Pair: SmoothFiller + ULTIMATE SMOOTH
SmoothFiller is designed to deliver a smooth, restructured feel in-salon, and incorporating the right care both during the service and at home helps keep hair looking and feeling its best between appointments. That’s why pairing a SmoothFiller service with ULTIMATE SMOOTH matters. Wella Professionals' most luxurious hair care line for smoother, shinier hair with less frizz features a nourishing formula with Squalane & Omega-9 that deeply nourishes hair inside and out, leaving it visibly smoother and shinier.
To treat and style after a SmoothFiller service and maintain the look and feel of the results at home, utilize the ULTIMATE SMOOTH regimen both in-salon and for home care.
