The verdict.
Olaplex is the Los Angeles bond-repair hair care brand that took a patented disulphide-bridging molecule from the colour-salon chair to the MECCA aisle. Glow Score 9.0/10. Best first product: the No.3 Hair Perfector at AU$45. Sulphate-free, colour-safe, the patent that built the category.
The Method, in five axes
How we scored 9.0.
Six weeks. Three hair types — bleached Type 2A, cotton-fine Type 1B, heat-styled Type 2C. Products purchased at MECCA — no PR samples accepted. See the full Glow Standard 2026.
- Formula
- Patent verified against published literature. The bis-aminopropyl diglycol dimaleate molecule registered to re-bridge disulphide bonds broken by lift. Sulphate-free across the at-home range. Marks down 0.3 only for a thicker conditioner film than panellists wanted in summer.
- Sensory
- Slip, scent and absorb time rated across six washes per panellist. Light herbal scent, no salon-bottle perfume. The towel-off feel is the cleanest in the colour-safe field; the conditioner has measurable but not heavy slip.
- Longevity
- A 100ml No.3 covers eight to twelve weeks of weekly use; the No.4 and No.5 250ml bottles cover six to eight weeks of daily wash on long hair. Shelf life 24 months sealed, 12 months once opened.
- Value
- Price-per-application benchmarked against Kérastase, Briogeo, Living Proof, K18. Olaplex sits mid-market on price-per-ml, top-quartile on patent strength. The pair-discount the colour desk earns when stocking both bottles.
- Accessibility
- MECCA stocks the full at-home range nationally. Adore Beauty carries it. Most working Australian salons stock the in-salon No.1 and No.2 plus the at-home range. The retail footprint that turns a one-time bond-repair buy into the default.
The Questions, asked most
Eight things readers actually ask.
- Is Olaplex worth it?
- Yes — Olaplex scores 9.0/10 in our review and is #1 in the 2026 Bond Repair Index. The No.3 Hair Perfector at AU$45 from MECCA is the editor-recommended first product. Sulphate-free, colour-safe, the patented disulphide-bridging molecule the colour desk runs daily.
- What is the best Olaplex product to start with?
- Olaplex No.3 Hair Perfector. It's the pre-shampoo treatment that introduces most readers to the brand — ten minutes on damp hair before the wash, the cortex repair is measurable at week three. From there, build to the No.4 and No.5 pair, then the No.8 mask once weekly.
- Where to buy Olaplex in Australia?
- MECCA stocks the full range nationally. Adore Beauty carries it. Most salons stock the in-salon No.1 and No.2 plus the at-home range. The No.3 Hair Perfector is the AU$45 hero SKU.
- Is Olaplex sulphate-free?
- Yes. The No.4 shampoo and the at-home range are sulphate-free, colour-safe and bond-safe. The patent is on the disulphide-bridging molecule that re-bonds the cortex; the formulations are built to deliver that chemistry without strip.
- Olaplex vs Kérastase — which is better?
- Olaplex (Glow 9.0) wins on chemistry — the bond-repair patent is the moat. Kérastase Elixir Ultime (8.9) wins on sensorial — five oils, salon scent, the highest shine premium in our test. Olaplex is the daily; Kérastase is the wash before the event.
- How often should I use Olaplex No.3?
- Once a week for healthy hair. Twice a week during peak damage windows — fresh bleach, summer chlorine, post-keratin. Leave on damp hair for ten minutes minimum before shampooing with No.4.
- Is Olaplex No.3 a mask?
- Technically a pre-shampoo bond-bridging treatment, not a deep-conditioning mask. It earns a hair mask category spot for the cortex repair payoff. For post-shampoo moisture, the No.8 mask is the pair.
- Is Olaplex safe for coloured hair?
- Yes — Olaplex was built for coloured and lightened hair. The patented chemistry is designed to repair the bonds that the bleach process breaks. The colour-desk default at most working Australian salons.

The Field Note, on Australian bond repair
From the colour chair, to the aisle.
Olaplex didn't start as a consumer brand. The original No.1 and No.2 were in-salon additives the colourist mixed into the bleach bowl — the move that let working salons take a client three levels lighter without snapping the cuticle. The colourists used it before the customers had ever heard of it. The brand sold to the trade first, the chair built the reputation, the MECCA shelf came later. That's the Olaplex arc.
The patent is the real story. Bond-repair chemistry isn't a marketing category — it's a registered molecule (bis-aminopropyl diglycol dimaleate) that bridges the disulphide bonds the bleach process breaks. The molecule is the moat. Kérastase and Briogeo and Aveda all sell "repair shampoos" now; none of them have the patent, none of them deliver the same cortex result on the panel. The colour desk runs Olaplex because the chemistry actually works, not because the bottle is pretty.
For the Australian buyer the easy entry is the No.4 shampoo at $49 from MECCA — the daily wash that pulls the routine into the bond-repair system. Add No.5 conditioner and you have the colour-desk daily. Add No.3 once a week and you have the editorial routine. The matched pair plus the pre-shampoo is the $143 starter kit that earns Olaplex its 9.0. Five SKUs, five reasons to keep re-buying, average panel result the strongest the index has seen.
