Olaplex No. 3 Dupes: 6 Bond-Building Treatment Alternatives (2026)
Pre-shampoo and leave-in bond-building treatments often compared with Olaplex No. 3 Hair Perfector, with what each listing and publication says, plus the original.
Short answerNo treatment is a copy of Olaplex No. 3, but The New Knew calls epres Bond Repair Treatment a legitimate swap because it uses a maleate ingredient from the same category of bond-repair chemistry. It is a different bond-building ingredient from the one The New Knew says Olaplex uses, so treat it as an alternative, not a match.

How to compare an Olaplex No. 3 alternative
- Check the bond-building ingredient. The New Knew says Olaplex No. 3 uses bis-aminopropyl diglycol dimaleate, and that epres uses diethylhexyl maleate, a different maleate ingredient. Other picks below name peptides, amino acids or a protein complex instead, which is a different approach again.
- Match the format. No. 3 is a pre-shampoo treatment you leave on before washing. Some alternatives here are pre-shampoo treatments and some, like K18, are leave-ins, so the routine changes.
- Read the claim carefully. Publications that call something a dupe are usually comparing the job it does, not the formula. Bustle's expert advises looking for "plex" in the name or for products that call out bond building, which is a naming clue, not proof.
- Look at your hair. Goldwell's Bond Pro is described by BEAUTYcrew as made for colored hair, while NAK is described as aimed at over-processed hair. Pick the one whose listing matches your damage.
- Treat every pick as an alternative, not a copy. None of these brands says its formula matches Olaplex's, and the bond-building ingredient differs from product to product.
7 picks and who each one suits
-
epres Bond Repair Treatment Starter Kit
Best for: Someone who wants the alternative with the closest published ingredient reasoning.
The New Knew says epres uses maleate-based chemistry and names diethylhexyl maleate as the key ingredient, describing it as part of the same category of bond-repair chemistry used by Olaplex. It is a different bond-building ingredient from Olaplex's, and the same article notes it is more about strength than softness. It also says the formula has only four ingredients and no fragrance.

Revolution Haircare Plex 3 Bond Restore Treatment
Best for: Someone who wants a plex-style treatment with a similar name and step number.
BEAUTYcrew lists it among three Olaplex No. 3 dupes and says it features the Revolution Plex triple molecular weight protein cascade system. That is a protein-based complex, so it is a different bond-building approach from Olaplex's ingredient.

L'Oreal Paris EverPure Bond Repair+ Pre-Shampoo Concentrate
Best for: Someone who wants a drugstore pre-shampoo treatment in the same step as No. 3.
A mass-market pre-shampoo concentrate from L'Oreal Paris, sold for bond repair, that goes in the same step as No. 3. No published comparison with Olaplex turned up in our research, so read its ingredient list before you choose it over the picks above.

NAK Structure Complex No.3 Bond Enhancer
Best for: Someone with over-processed or keratin-treated hair who likes a name that echoes No. 3.
BEAUTYcrew lists it among its Olaplex No. 3 dupes and says it addresses damage caused by over-processing, as a vegan, plant oil-rich formula that replaces your conditioner. Product names can vary by retailer, so check the version before you buy; the button is a search.

Goldwell Dualsenses Bond Pro 60sec Treatment
Best for: Someone with color-treated hair who wants a salon-brand bond treatment.
BEAUTYcrew lists it among its Olaplex No. 3 dupes and describes a peptide and amino acid-rich formula for colored hair that also hydrates and detangles. Peptides and amino acids are a different bond-building approach from Olaplex's ingredient. BEAUTYcrew names it the Bond Pro 60s Treatment, so check that you pick that one.

K18 Leave-In Molecular Repair Hair Mask
Best for: Someone open to a different kind of product: a peptide leave-in rather than a pre-shampoo treatment.
Bustle includes K18 in its Olaplex dupes roundup and says it uses peptides. It is a leave-in you apply after shampooing, so it works in a different step from No. 3 and uses a different bond-building ingredient.

The original: Olaplex No. 3 Hair Perfector
Best for: Anyone who wants to compare side by side, or who prefers to buy the original.
Bustle calls Olaplex's No. 3 Hair Perfector a cult-status treatment for repairing damaged strands. Olaplex's own site describes N°.3 as a 3-minute pre-shampoo treatment that is protein-free and lists bis-aminopropyl diglycol dimaleate in its ingredients. The button is a search, so check the current version and size.

Frequently asked questions
What is the best dupe for Olaplex No. 3?
No product is a copy, but The New Knew calls epres Bond Repair Treatment a legitimate swap because it uses a maleate ingredient from the same category of bond-repair chemistry. It is a different ingredient from Olaplex's, so expect a similar job rather than a matching formula.
Is there a drugstore dupe for Olaplex No. 3?
L'Oreal Paris EverPure Bond Repair+ Pre-Shampoo Concentrate is a mass-market pre-shampoo concentrate, so it sits in the same step as No. 3. No published comparison of it with Olaplex turned up in our research, so treat it as an option to compare rather than a proven match.
Do Olaplex alternatives use the same bond-building ingredient?
Not as far as the sources say. The New Knew names bis-aminopropyl diglycol dimaleate for Olaplex and diethylhexyl maleate for epres, while other alternatives use peptides, amino acids or a protein complex. Each is a different bond-building ingredient, so results may differ.
How we chose
This guide is desk research. We read published roundups from Bustle, BEAUTYcrew and The New Knew, plus Olaplex's own product page for the original, and chose treatments that are named as close in job or ingredient category to No. 3. We did not test any of these products; the notes come from those sources, and they describe what a publication or brand page says rather than how a treatment feels. A dupe is an alternative, never an identical formula.
Listings, sellers and sizes change quickly. At time of writing (October 22, 2026), every "Check price on Amazon" button on this page went to an exact Amazon listing for the product named, new and in stock; the three "Search Amazon for" buttons are searches because no exact listing could be confirmed. These products are not made or endorsed by Olaplex. Confirm the size, version and seller on the listing before you buy.
