Smoothing is getting smarter, and clients can feel the difference. Clients are looking for results that feel as good as they look: smoother hair, reduced frizz, and easier styling that lasts up to 3 months, with a finish that keeps natural movement and fades without visible regrowth. They also want the service experience to feel streamlined and comfortable, with modern details like carefully chosen ingredients, a low-fume experience, and no post-service restrictions.
That’s exactly where Wella Professionals SmoothFiller comes in—an under-2-hour in-salon service that fits seamlessly into schedules, including same-day color services, so clients can wash their hair, work out, swim, or tie it up the same day. That flexibility matters just as much as the result. Because SmoothFiller can be performed alongside same-day color services, it becomes an easy, high-impact add-on that doesn’t require clients to book a separate appointment or come back another day—this helps you maximize appointment times, increase your average ticket value, and streamline the entire salon experience.
Meet Wella Professionals SmoothFiller
Wella Professionals SmoothFiller is a salon-exclusive service that delivers smoother hair, reduced frizz, and easier & faster styling that lasts up to 3 months—without the usual compromises clients associate with smoothing treatments. It’s designed to work with the hair, and with a single-product approach, it fits into your salon and your schedule. That simplicity also makes SmoothFiller an easy add-on during color appointments, allowing you to introduce smoothing as a value-added service without disrupting your existing workflow.
All of the Upsides, None of the Downsides
SmoothFiller stands out because it modernizes smoothing—delivering all the upsides of a smoothing service, with none of the downsides. This on-trend service is under two hours, fits easily into a busy salon day, and pairs seamlessly with same-day color. Clients can wash their hair immediately, work out, swim, or tie it up the same day—with results that fade naturally without visible regrowth. For salons, this modern approach translates directly into opportunity. SmoothFiller is a powerful add-on service that requires little extra time, making it easy to integrate into a busy day without extending appointments or creating scheduling issues.
Behind the chair, it’s simple too. It’s one product with no complicated steps, and low odor with minimal fumes during heat activation. The formula features just 8 carefully chosen ingredients and is vegan, fragrance-free, silicone-free, and doesn’t require a sulfate-free shampoo—making aftercare effortless and restriction-free.
Why SmoothFiller Works as a Same-Day Add-On
SmoothFiller is designed to pair seamlessly with color services, making it an easy upsell to your existing color clients. It takes just 30 minutes total during a color appointment—approximately 10 minutes to apply and 20 minutes to process—so it fits naturally into the timing of a standard color service.
Because SmoothFiller can be performed on the same day as color, clients don’t need to return for a separate visit, which increases convenience for them while helping the salon maximize productivity and profitability behind the chair. Whether added during a root retouch, highlight service, or gloss appointment, SmoothFiller allows you to deliver noticeable results while increasing service value with a few simple add-ons.
Who SmoothFiller Is For
SmoothFiller is made for the client who wants hair that feels easier to live with—especially the ones who tell you their blowdries don’t last, their hair takes forever to smooth, frizz shows up fast, or there’s one area they can’t control. It’s ideal for hair that’s naturally frizzy, difficult to manage, or prone to humidity-induced frizz, where porosity can make hair more vulnerable to moisture in the air and harder to style consistently.
How It Works Without the “Coating” Effect
SmoothFiller is designed to work from within, not by creating an artificial coating on the hair’s surface. With its Smart Delivery System, the active ingredient penetrates deep inside the hair, and through thermal activation, the organic acid fills the hair protein structure by creating new, stable, longer-lasting bonds that help restructure the hair internally. This is what supports up to 3 months of incredible smoothness, effortless styling, less frizz, and natural movement.
Made to Pair with Color Services
*with a few considerations
The ability of SmoothFiller to work alongside color services makes it an essential business decision—allowing salons to enhance finished results while increasing service revenue during a single appointment. That same day compatabilty is also one of the biggest reasons SmoothFiller stands out in the salon–it’s built to integrate seamlessly into your existing schedule.
SmoothFiller can work alongside color and lightener services in these ways:
- Root retouch with permanent color can be done before SmoothFiller
- Highlights should be done before SmoothFiller
- Hair can be glossed immediately after SmoothFiller, though the color result may be less intense than usual
- SmoothFiller may shift colored hair’s tone to lighter and/or warmer; do not overlap SmoothFiller and flat iron over freshly colored roots
- With permanent color on mid-lengths and ends, wait for 5 washes
1 Shinefinity and BlondorPlex Cream Toners are not recommended right after Smoothfiller They are safe to use; however, the tone will not be as rich/not true-to-tone as expected.
2 When using BlondorPlex, do not use WellaPlex No. 2. Up to 97% less breakage results are not guaranteed.
What the Service Experience Looks Like In-Salon
SmoothFiller is designed to feel simple, polished, and easy to build into a busy salon day—and it’s streamlined by design with a single product, so there’s nothing complicated to mix or layer.
- It starts with prepping the hair so it’s clean and ready for even absorption, then the product is applied with controlled sectioning and allowed to develop for 20 minutes—no heat, no covering, and no unnecessary steps.
- After rinsing, the service moves into thermal activation, which is where the result is set. Hair is blow-dried smooth and then flat-ironed in small sections with heat. The heat settings and the number of passes are determined based on your client’s hair structure and the finish you’re aiming for, so you can tailor the outcome while keeping natural movement.
- The full service is completed in under two hours and is designed to feel comfortable for the client from start to finish.
Keeping Results Looking Fresh Between Visits
For best results, schedule check-in appointments every 6–8 weeks in case touch-ups are needed. During these visits, incorporate ULTIMATE SMOOTH as part of the in-salon service to enhance softness, manageability, and frizz control, then set clients up with the ULTIMATE SMOOTH care regimen as their at-home maintenance plan to preserve and enhance SmoothFiller results between appointments.
This in-salon to at-home routine is designed to keep hair looking polished by maintaining softness, manageability, and frizz control between salon visits. The regimen provides nourishment in 30 seconds, smoothness that lasts up to 3 days¹, and up to 85% smoother hair²—helping clients keep that SmoothFiller look and feel until their next visit.
The Steps:
- Start with ULTIMATE SMOOTH Shampoo, a color-safe nourishing cleanser that lathers into a luxe foam to remove impurities and prep dry, dull hair for deep nourishment. It’s also formulated with Metal Purifier technology to help detox hair from metals.
- Follow with ULTIMATE SMOOTH Conditioner, applied through lengths and ends for 30 seconds to 3 minutes, to nourish inside and outside the hair for visibly smoother, shinier results while reducing frizz.
- For clients who need an extra boost (or who are feeling the season’s dryness and humidity), recommend the ULTIMATE SMOOTH Mask once a week. Apply to clean, damp hair for 5–10 minutes, then rinse thoroughly to deeply nourish and keep hair looking sleek and reflective.
- To protect their smooth, finish with ULTIMATE SMOOTH Miracle Oil Serum through mid-lengths and ends. This delicate oil serum deeply nourishes inside and out, delivers 96 hours of frizz control³, and helps protect from UV and heat (230°C/450°F)—making it ideal before styling and for a final smooth, silky finish.
- For best results, have your clients apply 1–3 pumps on damp lengths and ends, comb through, and wait 30 seconds before styling. They can also add a small amount to finish (or anytime they want added smoothness and shine).
