Collection: Smoothing Shampoo

Smoothing Shampoo

Smoothing shampoo hydrates the hair shaft and seals the cuticle using nourishing ingredients like argan oil, keratin, and shea butter, softening strands and protecting against humidity for sleek, glossy, more manageable hair.
Frizz is a symptom. Texture is the cause. A proper smoothing shampoo doesn't just fight humidity for a day; it gradually relaxes the wave pattern, reduces bulk, and leaves hair sitting visibly straighter on the brush, wash after wash. This is different from anti-frizz products, which target the cuticle. Smoothing targets the texture itself. Our AMR smoothing range includes everything from 12 Reasons (Argan, Marula, Keratin), Paul Mitchell, Limitless F1, Brasil Cacau, E18HTEEN Thirst Trap, and BackBar to other salon-favourite smoothing formulas, all shipped Australia-wide as part of our full shampoo range.

What to Look for in a Smoothing Shampoo

Three things separate a real hair-smoothing shampoo from a standard moisturising wash. 

First, the smoothing system has to deposit weight. Oils (argan, marula, coconut) and butters add mass to the strand, which pulls waves and curls straighter. Second, the formula needs keratin or amino acids if your hair is damaged as well. Smoothing damaged hair without protein just makes it smoother and weaker. Third, the shampoo should be sulphate-light or sulphate-free. Sulphates strip the very weight you're trying to build, especially on colour-treated or chemically smoothed hair.

Smoothing Shampoo vs Anti-Frizz Shampoo

People use these terms like they're the same. They're not. Anti frizz shampoo seals the cuticle to block humidity and stop the strands from swelling unevenly. Smoothing shampoo adds weight and bulk to the fibre itself, so the natural wave pattern relaxes over time. If your main problem is humidity making hair puff up, start with an anti-frizz product. If your main problem is that your hair has texture you don't want (waves, bulk, volume), smoothing is the right place to start. Many people use both on rotation, smoothing as the main wash, and anti-frizz on humid days.


Using Smoothing Shampoo Properly

Every smoothing shampoo in our AMR range follows the same logic, with frequency set by how much texture you're trying to calm.

  • Rinse hair with warm water for 30 seconds. Heat helps the smoothing agents penetrate.

  • Does a 20-cent piece for shoulder-length hair. Smoothing shampoos are often richer, so you don't need to use as much as you would for a daily wash.

  • Emulsify in palms, then focus the lather primarily on the scalp, letting the suds gently cleanse the ends as you work it down through the lengths.

  • Leave on for 2 minutes minimum. The smoothing agents need time to deposit.

  • Rinse with cool water to seal the cuticle flat.

  • Always pair with the matching smoothing conditioner from mid-lengths down. The conditioner locks in the moisture and seals what the shampoo just opened.

Frequency: wavy or curly hair you want to relax needs smoothing every wash for the first 2 weeks, then every 2–3 washes. Naturally straight but frizz-prone hair does best with smoothing 1–2 times a week, alternated with a lightweight everyday shampoo. Fine hair that flattens easily should not use smoothing daily, it will look limp by midday.

Smoothing Shampoo for Wavy, Thick, Coarse, and Chemically Smoothed Hair

Different textures need different smoothing formulas. wavy hair (type 2) responds best to oil-rich formulas that add just enough weight without killing movement. Thick, coarse hair needs heavier smoothing agents like keratin and shea butter. Chemically smoothed hair (keratin treatment, Brazilian blowout, nanoplasty) needs a sulphate-free formula that won't strip the treatment. See our wider keratin shampoo range for similar aftercare options. Colour-treated smoothing clients should pair their wash with a tone-safe formula from our colour shampoo range on alternate days. Hair that's both wavy and damaged should start with a bond-rebuilding formula from our repairing shampoo collection for structure, then layer smoothing in via the conditioner instead of the shampoo.

Why Buy Smoothing Shampoo From AMR

AMR carries the same smoothing shampoos salons use at the basin, in the same sizes, at trade-friendly prices. That means professional formulas with proper weight concentration and salon-grade ingredients, the kind that deposit enough oil or keratin in one wash to hold the smoother texture for 48 to 72 hours. Supermarket versions dilute the smoothing agents to keep costs down, so the wave pattern bounces back within a day. Our range covers salon back-bar 1L sizes next to smaller retail bottles, plus 5L BackBar options for high-volume salons.  Salons buying in bulk should also consider our Bulk Shampoo range.

Making The Smoothness Last

Smoothing shampoo is step one. Step two is a matching nourishing conditioner, applied from the mid-lengths down and left on for 2–3 minutes. Step three is a leave-in conditioner, smoothing cream, or serum, applied to damp hair before blow-drying. Step four is a weekly conditioning hair mask to lock in the texture change. For the fastest visible result, blow-dry hair straight with a paddle brush after washing, because heat sets the smoother texture into the strand.

Argan oil is the lightest, best for wavy or normal hair that just needs weight. Marula oil is richer and better for dry or thick hair that needs moisture and smoothing. Keratin is the heaviest and most repair-focused, best for damaged hair that needs both smoothing and structural rebuilding. All three are smooth. They just serve different starting points.

You can, but understand what it does. Smoothing shampoo will relax the curl pattern over time, making curls looser and less defined. If you want that, yes. If you want your curls to stay tight and bouncy, stick to a dedicated Curly Hair Shampoo instead. Smoothing and curly routines work against each other.

Two to three times a week for most people. Daily smoothing shampoo on fine or thin hair will drag it flat and make it look greasy faster. On thick or coarse hair, daily is fine because the extra weight is exactly what that texture needs.

Yes, but check the label for sulphates. 12 Reasons Argan and Marula are both sulphate-free. 12 Reasons Keratin is sulphate-light. Limitless F1 is sulphate-free. Avoid smoothing shampoos with sodium lauryl sulphate if you've had a recent colour service, because they'll strip the tone along with the texture.

Technically, yes, but you shouldn't. Smoothing shampoo deposits weight and oils, but it also lifts the cuticle to get those ingredients in. The conditioner is what seals the cuticle back down. Skip the conditioner, and the smoother texture won't hold past the first night's sleep. Always pair them.

Start with smoothing as your main wash (2-3 times a week), then keep a dedicated anti-frizz shampoo for humid days or travel. The smoothing shampoo reduces the underlying wave pattern. The anti-frizz shampoo blocks humidity from making the remaining waves puff up. They're a team, not competitors.
