How Does SmoothFiller Work?

If you’re dealing with frizzy hair, it’s often due to gaps and weakened areas within the hair shaft, which make strands more susceptible to humidity. SmoothFiller uses a Smart Delivery System to target these areas, allowing the active smoothing ingredient to penetrate the hair cuticle and reach the cortex. Once inside, it helps refill and restructure the hair fibre from within by supporting the formation of new internal bonds. The result is smoother, more controlled hair with reduced frizz, enhanced shine, and easier, more effortless styling.

What Can I Expect When I Go to the Salon?

Ready to book your first SmoothFiller™ service? Just head to our Hair Plus salon in New Brighton or contact us here to make a booking. The smoothing treatment is completed in three steps, putting you on the fast-track to beautiful hair. Here's what to expect:

Step 1: Preparation

First, one of our stylists will wash your hair to ensure it’s clean and prepared to absorb the treatment.

Then, they’ll blow-dry your hair until it’s around 80% dry. Hair needs to be slightly damp in order for the smoothing treatment to penetrate.

Step 2: Application

Next, SmoothFiller™ is applied. Your stylist will apply the solution evenly on your hair (avoiding the scalp) and then allow it to develop for 20 minutes.

Once developed, your hair is thoroughly rinsed. During the development time, the product penetrates inside the hair, and any residue is removed by rinsing.

Step 3: Activation


After the treatment has been rinsed out entirely, your stylist will blow-dry your hair until it’s completely dry. They’ll then flat iron your hair in small sections with multiple passes until every strand has been smoothed out. The heat activates SmoothFiller™’s ingredient to unlock the smoothing results. And just like that, your SmoothFiller™ service is complete.

Hair can be toned with Color Touch, our demi-permanent color, right after, even during the same service appointment, but it’s not necessary. SmoothFiller will give you shinier hair* (*versus untreated hair)

Your Day-to-Day Smoothing Regimen


After you leave the salon, you can wash your hair as soon as you want to, and with any shampoo formula you choose. This is one of our favorite things about SmoothFiller™: there are no restrictions on your daily regimen. But if you want to follow a ritual that’s all about smoothness, why not try ULTIMATE SMOOTH?
