Best shampoo in Australia, 2026.

Every GLOW ranking runs the same five-axis rubric. Weights are published.

GLOW Standard scores every shampoo against five axes, formula (30%), finish (25%), slip (15%), shine (15%), value (15%), with weights set by what daily panellists actually optimise for. Formula carries the most weight because a shampoo touches the scalp and the cortex; a wrong surfactant pulls colour faster than the colourist meant.

Finish is the second axis: how the hair reads at the towel-off, the air-dry and the blowdry stages. Slip and shine are tracked separately, the patent oils that win on shine sometimes lose on grip for fine roots. Value pulls the salon-only formula and the MECCA receipt onto the same chart by modelling per-millilitre cost against the panel result at week three.

Every shampoo in this ranking ran a four-week daily-wear panel in-house with GLOW hair desk. Three hair types, bleached and coloured Type 2A, cotton-fine Type 1B, over-styled and heat-trained Type 2C, were measured at the towel-off, the air-dry and the blowdry stage. The towel-off axis is where most shampoos lose, the wrong surfactant load reads as squeak.

Each formula was paired with its matched conditioner where possible and a neutral conditioner control on the alternate wash. Colour fade was measured against a Day 0 swatch under daylight and salon-warm light. Style hold was tracked from the blowdry through to Day 3.

Olaplex at $49 was judged on the same five-axis rubric as Kérastase at $62. A salon-only formula does not get a category-winning seat unless it earns a stockist that an Australian buyer can actually walk into, Adore Beauty, MECCA, the major salon counters.

On formula.

Olaplex No.4 wins the formula axis on its patented bond chemistry, not a slogan, a registered molecule that re-bridges disulphide bonds broken by lift. Kérastase Elixir Ultime takes second on a five-oil cocktail dialled for shine over repair. Briogeo Don't Despair, Repair! holds the cleanest ingredient list. Living Proof carries the Healthy Hair Molecule moat for fine hair; Olaplex No.4C rotates in weekly as the chelating reset.

On finish.

Olaplex No.4 reads as clean strength, the cortex feels rebuilt at week two. Kérastase reads as polish; the shine premium at blowdry is the highest in the test. Briogeo reads as softness; Living Proof reads as lift. The No.4C Clarifying reads as squeak, the right finish for the weekly reset, not the daily wash.

On slip and shine.

Kérastase leads on shine; Olaplex leads on slip during the conditioner pass. The two are the standard pairing for coloured hair at salon counters, bond chemistry plus oil polish, and the desk's hair colourist uses both in rotation.

On value.

Living Proof at $44 is the price floor in this field; Briogeo at $48 and Olaplex at $49 sit a step above. Kérastase at $62 buys the shine premium and the salon scent profile, the only premium price the Standard cleared this cycle. The stripped-list brands, Pureology, Davines, Aveda, sit between $40 and $58 and earned honest mentions without earning a photograph.

For a decade the shampoo top seat belonged to the salon-luxury brands, Kérastase, Pureology, Davines. Five oils, recyclable packaging, the back-of-bottle ingredient lists nobody could read but everybody respected. Then Olaplex showed up with a patent.

The patent matters because shampoo is the one product in a hair routine that has to be both functional and chemically forgiving. The cortex is exposed during the surfactant pass. A wash that strips lipids faster than the cuticle can recover is a wash that asks the conditioner to do twice the work. Olaplex No.4 is the first shampoo where the wash itself is part of the repair, the bond-bridging happens on the way down the drain. That is the moat. Kérastase Elixir Ultime is the closest competitor on shine but not on chemistry, which is why it sits second at $62 and not first at any price.

The three brands stripped to the list, Pureology, Davines, Aveda, all cleared the rubric. They lost on photographic ranking because none of them carry the patented chemistry that Olaplex earned its 9.0 with, and none of them carry the sensorial premium Kérastase earned its 8.9 with. They are honest competent shampoos, the right buy if Olaplex is sold out or if a clean ingredient list ranks above patent chemistry in your house. Five winners, three honourable mentions, average GLOW Score 8.74, the strongest the shampoo index has run since we built it.
