I’ve rounded up the best Olaplex dupes to elevate your hair repair routine without sacrificing money or quality. 

You’ve probably seen Olaplex gracing your Instagram and Tiktok feeds—their products have become super popular over the last year.

Olaplex is a luxury haircare brand that’s taken the industry by storm. They’re known for their magical multi-step hair treatment products that target damaged hair but come with a price tag of $30 per product. 

I collected all of the best Olaplex dupes and kept them all under $20. To make it easier to find the dupe you’re looking for, I’ve divided them up by Olaplex system steps.

Top 8 Olaplex Dupes

Olaplex No. 0 Dupe: Elizavecca cer-100 collagen coating hair protein treatment

Olaplex No. 0 is the intensive bond-building hair treatment known as the bond multiplier. 

Elizavecca cer-100 collagen coating hair protein treatment is a hair mask that includes collagen and Ceramide 3. The product description says this mask is great for treating damaged or over-processed hair and is suitable for all hair types, similar to the Olaplex No. 0. 

Retailing at only $8, this No. 0 dupe is the perfect first step in your hair care routine. With over 24,000 5-star amazon reviews, you can rest assured that this product is just as magical as Olaplex.

Olaplex No. 3 Dupe: Hair Plex 3 Bond Restore Treatment

Olaplex No. 3 is the second step in the haircare system, the acidic bonding concentrate. It’s a reparative, pre-shampoo treatment that helps to reduce breakage and split ends. It claims to repair broken bonds for smoother, softer, and healthier hair. 

I found the perfect Olaplex No. 3 Dupe, the Hair Plex 3 Bond Restore Treatment from Revolution haircare that also includes a bonding concentrate. With similar goals, the Hair Bonding Plex 3 is to be used before your shampoo and conditioner. 

This product retails for $14 and uses the signature Revolution hair plex system to restore and strengthen hair damage. This dupe is a great alternative to the No. 3 and doesn’t break the bank.  

Olaplex No. 4 and No. 5 Dupe: L’Oreal Ever Pure Shampoo and Conditioner

Olaplex No. 4 is their signature bond maintenance shampoo that repairs damage while cleansing the hair. Olaplex recommends using it along with Olaplex No. 5. 

Olaplex No. 5 is their signature bond maintenance conditioner that still works to bond repair hair damage while also untangling hair. 

There are a lot of shampoo and conditioner systems that target different hair care needs. But, the most similar to Olaplex is the L’Oreal Paris Ever Pure Bond Strengthening shampoo and conditioner. 

The L’Oreal system targets damaged hair and strengthen hair by reinforcing weak hair bonds. These products have changed the hair game for many Amazon, Target, and Ulta reviewers. 

A perfect dupe for the Olaplex No. 4 and No. 5, the L’Oreal Paris system totals around $20 instead of the $60 you’d spend if you bought both Olaplex No. 4 and No. 5. 

Rest assured that these products also qualify as clean haircare. This is a vegan dye-free formula that is free of parabens and sulfates. And don’t worry—they’re also color safe.

Olaplex No. 6 Dupe: The Inkey List PCA Bond Repair Treatment

Olaplex No. 6 is the leave-in reparative styling cream that protects hair from future damage. A key component to the repair hair treatment is the bond repair that works from the inside out.

The Inkey List PCA Bond Repair Treatment is the perfect dupe, as it does all of the same things. The Bond Repair treatment is a spray that repairs, protects, and strengthens hair from color, bleach, or heat damage. 

This product retails for only $14, making it half the cost of No. 6—what a deal! The bond repair treatment is also free of any sulfates or parabens, making it a clean hair-care product, just like No. 6. 

Olaplex No. 7 Dupe: Reparative Styling Hair Oil

Olaplex No. 7 is a bonding hair oil that increases shine and prevents heat damage while taming flyaways. 

The Reparative Styling Hair Oil from Derma-E strengthens hair and adds shine while also decreasing frizz. 

Jojoba oil is used to moisturize hair while preventing split ends. Similar to Olaplex No. 7, this is a clean hair care product free from parabens or sulfates. 

This hair oil packs a hydrating punch and only costs $13, which is less than half of the cost of No. 7—talk about a good dupe! 

Olaplex No. 8 Dupe: Twist Bond Hair Restoring Mask

Olaplex No. 8 is a deep conditioner, restore bonding mask that helps to repair hair damage and replenish hydration. It’s recommended that this product is used in place of the conditioner at least once a week. 

Twist Bond Hair Restoring Mask is a great dupe option for No. 8. It can be used as a deep conditioner or repair hair mask and an overnight treatment mask. 

For $13.99, this mask uses bond-repairing technology to fight against breakage and adds intense moisture. It costs less than half of No. 8 and targets the same hair care concerns. 

Olaplex No. 9 Dupe: Eva NYC Mane Magic End Mender  

Olaplex No. 9 is the last step in their haircare line, a leave-in reparative styling serum that helps to add shine, smooth the hair, and protect against heat damage while helping to detangle and smooth frizz. 

The Mane Magic 10-in-1 End Mender from Eva NYC is a clean hair care serum that retails for $14. It targets split ends while also mending stronger hair for less future breakage. 

With Argan Oil and other plant proteins, this serum’s hydration is marketed as Eva NYC’s magical potion. This 10-in-1 serum is a notable alternative for the No. 9.
