Introducing the SmoothFiller™ Service: For Up to 3 Months of Silkier Hair
At last – an answer to the question, “how do I tame my frizzy, unruly hair?” Introducing SmoothFiller™, the solution to quick, easy styling for clients struggling with an unmanageable mane. The salon service, carried out by you, delivers long-lasting results that stay flawless for up to three months, so even when humidity hits, the SmoothFiller™’s restructuring benefits ensure silky, smooth hair that resists damp air.
But, what makes SmoothFiller™ so effective? And how can you bring the demi-permanent smoothing treatment to your clients? Keep scrolling for your everything guide to the smoothing treatment that’s like nothing you’ve ever tried…
What is SmoothFiller™?
SmoothFiller™ is a salon-exclusive, demi-permanent hair smoothing treatment, designed to reduce frizz, speed up styling time, and give your clients more manageable hair that lasts up to three months.
We formulated it for clients who:
- would like their daily styling to be quicker and easier;
- hope to reduce frizz;
- love a silky-smooth blow-dry;
- dread the frizz-inducing effects of humidity;
- are searching for a long-lasting solution to smoother hair.
How Does SmoothFiller™ Work?
Hair that’s prone to frizz usually has gaps and tears along the cuticle. These gaps make the hair highly porous and absorbent, causing it to seek out and soak up moisture from the air – cue frizz. SmoothFiller™ works to refill these gaps with a Smart Delivery System, which ensures the active smoothing ingredient penetrates the hair cuticle, and goes straight into the cortex.
Once there, the ingredient refills and restructures the hair fiber, creating more bonds inside the cortex for a silkier result. This not only reduces the appearance of frizz, but it also makes the hair more resistant to humidity. And, best of all, the results last for up to three months – so your client enjoys smoother hair for longer.
Your Clients Will Love SmoothFiller™ If…
they regularly complain about frizz and have been asking for your advice;
- they find their hair tricky to tame (and they’re always asking, “how did you do that?!” after you’ve blow-dried their hair);
- they often enter your salon with their hair in a bun because styling takes too long;
- they want a smoothing solution that lasts – SmoothFiller™ results stay in place for up to three months;
- they don’t like the harsh regrowth they see with other smoothing treatments. SmoothFiller™ fades softly over time, preventing demarcation lines;
- they find other smoothing treatments too fume-y. SmoothFiller™ is a low-fume treatment that makes for a more comfortable salon experience.
Step-by-Step: How to Apply SmoothFiller™
Ready to carry out a SmoothFiller™ service? All you need is the SmootherFiller solution, a flat iron, and these steps…
Step 1: Preparation
First, wash your client’s hair to ensure it’s clean and ready to absorb the solution. You can use any shampoo for this step, but a clarifying shampoo may be your best option to remove any product build-up. Then, blow-dry the hair until it’s around 80% dry. It needs to be slightly damp in order for the SmoothFiller™ treatment to penetrate the hair shaft.
Step 2: Application
Next, apply SmoothFiller™ evenly through your client’s hair, working layer by layer while avoiding the scalp. Allow it to develop for 20 minutes, so the treatment can penetrate the hair, before rinsing thoroughly – no shampoo needed.
Step 3: Activation
After the treatment has been fully rinsed out, blow-dry your client’s hair until it’s 100% dry. Then, use a flat iron to straighten the hair and activate the SmoothFiller™™ active ingredient. Pro tip: Try flat ironing the hair in small sections, with multiple passes, until every strand is smooth. Just like that, the SmoothFiller™ service is complete.
Does Your Client Want Color Next?
No problem. While many smoothing treatments aren’t color-compatible, SmoothFiller™ lets you color your client’s hair in the very same appointment. For this, use Color Touch, Wella Professionals’ demi-permanent formula. With more than 90 shades available, it veils hair in true-to-tone vibrancy and shine for stunningly glossy results.
How Should Clients Care for Hair Post-Treatment?
SmoothFiller™ comes with no post-service restrictions. Your client can wash their hair as soon as they like, with any shampoo formula they choose – even if it has sulfates. We love following it up with the ULTIMATE SMOOTH regimen for inside-out nourishment. So, instead of sharing a long list of ‘dos and don’ts’ after their treatment, why not recommend these products to your client?
This shine-boosting shampoo kicks off their regimen with a deep yet gentle cleanse, removing dulling impurities to prep strands for their next nourishing steps. With a luxurious lather, it enhances your client’s experience from backwash to shower, leaving their hair feeling clean and cared for in seconds.
If your client’s hair is frizz-prone, they should always follow shampoo with conditioner. ULTIMATE SMOOTH Conditioner is a creamy, dreamy formula that boosts hair health without weight strands down. Advise your client to apply it to the mid-lengths and ends only, then let it absorb for up to three minutes. That silky, swishy sensation will be theirs from the first wash.
On days when your client craves more intense nourishment, this sumptuous mask delivers. Its smoothing blend of Squalane and Omega-9 cares for strands from the inside out, giving them up to 85% smoother hair*. Remind your client to squeeze excess water out of their hair before they apply it, so the rich formula is able to penetrate deep and truly transform frizz-prone lengths.
We don’t call it a miracle for nothing. This luxurious oil has a visible and lasting impact on the texture of the hair, ensuring nourishment in 30 seconds and smoothness that lasts up to 3 days**. Plus, it’s a major multitasker. Tell your client they can use it as:
- a pre-shampoo treatment to protect dry, dull lengths while they wash their hair;
- a mask booster. Mix a drop of oil with ULTIMATE SMOOTH Mask in the palms of hands to supercharge the smoothing results;
- a heat protectant and UV shield. The indulgent oil shields while adding shine;
- an everyday styler. On damp or dry hair, it tames flyaways to leave hair with a mirror-like finish.
