Olaplex No.3 dupes, ranked by how you use them and what is in them

The closest Olaplex No.3 dupe is L'Oreal Paris EverPure Bond Repair+ Pre-Shampoo Treatment: $9.97 for 5.1 oz vs $34.00 for 3.3 oz of Olaplex N°.3PLUS, the formula now replacing No.3. You use it the same way, before shampoo, for about a fifth of the price per ounce. No cheaper product we checked has Olaplex's patented bond ingredient: same steps, different ingredients.

Quick answers

Is Olaplex No.3 discontinued?
Mostly. Olaplex says N°.3PLUS is replacing the original No.3. The old No.3 page on olaplex.com now opens N°.3PLUS, and some stores still have the old bottles. N°.3PLUS is a 3-minute pre-shampoo step; the old No.3 said 10 minutes or more.
Does any dupe have the same bond ingredient as Olaplex?
No. Olaplex's patented ingredient (bis-aminopropyl diglycol dimaleate) is 2nd on the classic No.3 list and 4th on N°.3PLUS. None of the cheaper products we checked lists it. They use citric acid, proteins, oils or a peptide instead.
Is Redken Acidic Bonding Concentrate the same as the L'Oreal one?
Nearly. Redken's Acidic Bonding Concentrate pre-shampoo treatment shares 15 of L'Oreal EverPure Bond Repair+'s 15 ingredients, and the first 9 are in the same order (both lists are printed below). Both brands belong to L'Oréal. The Redken one costs more.
Is K18 better than Olaplex?
It works differently: K18 uses its own peptide and you leave it in, while Olaplex rinses out. It is not a cheaper swap. At $75.00 for 1.7 oz it costs more per ounce than Olaplex.

01 / The ranking

The 4 Olaplex No.3 alternatives, ranked

How we rank: none of these has Olaplex's bond ingredient, so we rank by routine first. A rinse-out treatment you use before shampoo, like No.3, comes first. Then we count how many of N°.3PLUS's 56 ingredients each one shares, then price per ounce.

How Olaplex N°.3PLUS feels: A white conditioning cream you put on damp hair before shampoo, leave for a few minutes and rinse. It has a light fragrance and leaves hair softer before you wash.

  1. L'Oreal Paris EverPure Bond Repair+ Pre-Shampoo Treatment

    1. L'Oreal Paris EverPure Bond Repair+ Pre-Shampoo Treatment

    How you use it: pre-shampoo, 5 to 10 minutes, rinse · shares 10 N°.3PLUS ingredients · $9.97 for 5.1 oz ($1.95/oz)

    How it feels: A white conditioning cream with no silicones on the list. It goes on damp hair before shampoo and rinses out. Sulfate-free, with a light scent.

    Best for the same step for far less. It is used exactly like No.3: on damp hair before shampoo, then rinsed. Its bond care is citric acid, not Olaplex's patented ingredient. Redken's Acidic Bonding Concentrate pre-shampoo lists nearly the same ingredients (both brands belong to L'Oréal).

    Trade-off: No cheaper product has Olaplex's bond ingredient, so this is the same routine with a different chemistry, not a copy.

  2. Mielle Babassu & Mint Damage Repair Bond Treatment

    2. Mielle Babassu & Mint Damage Repair Bond Treatment

    How you use it: after shampoo, 10 minutes, rinse · shares 15 N°.3PLUS ingredients · $13.94 for 5.5 oz ($2.53/oz)

    How it feels: A rich cream with jojoba, castor and sunflower oils and a peppermint scent. You leave it on for 10 minutes after shampoo, then rinse.

    Best for very dry, textured or relaxed hair. A richer rinse-out treatment made for damage from relaxers, heat and color, with oils and wheat protein.

    Trade-off: It is used after shampoo, not before, and Mielle says every 4 to 6 weeks. It has peppermint and fragrance.

  3. Eva NYC Therapy Session Deep Conditioning Hair Mask

    3. Eva NYC Therapy Session Deep Conditioning Hair Mask

    How you use it: after shampoo, rinse · shares 11 N°.3PLUS ingredients · $15.97 for 13.5 oz ($1.18/oz)

    How it feels: A creamy mask with jojoba, argan and a silicone that softens and smooths. It is a conditioning mask, not a bond treatment.

    Best for softness for the lowest price per ounce. A big 13.5 oz tub, the lowest price per ounce here. It is built on the same kind of conditioning base as No.3 (water, fatty alcohols, conditioners).

    Trade-off: It makes no bond-repair claim at all. It smooths and softens; it does not do what Olaplex says No.3 does.

    Buy on Amazon $15.97
  4. K18 Leave-In Molecular Repair Hair Mask

    4. K18 Leave-In Molecular Repair Hair Mask

    How you use it: leave-in, 4 minutes, no rinse · shares 9 N°.3PLUS ingredients · $75.00 for 1.7 oz ($44.12/oz)

    How it feels: A light leave-in with alcohol in the base. It adds little moisture and is meant for hair that snaps from bleach, color and heat.

    Best for a different repair method. K18 uses its own peptide (sh-Oligopeptide-78) instead of Olaplex's ingredient, and you do not rinse it out.

    Trade-off: It is not cheaper: it costs more per ounce than Olaplex. Think of it as the other premium option, not a dupe.

06 / Questions

Frequently asked

What is the best dupe for Olaplex No.3?
L'Oreal Paris EverPure Bond Repair+ Pre-Shampoo Treatment. Like No.3, you put it on damp hair before shampoo and rinse it out. It costs $9.97 for 5.1 oz ($1.95/oz) vs $10.30/oz for Olaplex. It uses citric acid instead of Olaplex's bond ingredient.
What is the cheapest Olaplex No.3 alternative?
Per ounce, Eva NYC Therapy Session Hair Mask: $15.97 for 13.5 oz ($1.18/oz). It is a softening mask, not a bond treatment. Revolution Haircare Plex 3 is another cheap pre-shampoo pick; it is left out of the ranking because on Amazon it comes only from other sellers.
