Looking for a cheaper alternative to the OLAPLEX No.4 Bond Maintenance Shampoo (250 mL)? It usually sells for about $34. Here are 4 cheaper swaps from $11: the Matrix Instacure Build-A-Bond Mighty Bonds Shampoo (10.1 oz) is the closest match from another brand, the OLAPLEX No.4 Bond Maintenance Shampoo (100 mL) is a cheaper option from OLAPLEX and the L'Oreal Paris EverPure Sulfate-Free Bond Repair Shampoo (6.8 oz) is the cheapest at about $11.

The OLAPLEX No.4 Bond Maintenance Shampoo (250 mL) ($34) is worth it if you have medium to coarse hair that is colored, bleached or otherwise chemically treated and you want Olaplex's patented bond builder (bis-aminopropyl diglycol dimaleate) in a daily shampoo. Olaplex says it is free of SLS/SLES sulfates, vegan and color-safe, and that it is concentrated enough to start with a dime-size amount. Its “3X stronger” result is for No.4 used as a system with the No.5 conditioner.

Each swap links to amazon.com. Prices are typical US prices checked October 2026 and change often, so check the listing before you buy.
Every swap is a product sold in the US that does the main job of the original. Close match is another brand with similar features, Same brand, cheaper is an older, smaller or renewed model from the same maker, and Budget pick is the cheapest thing that still does the job. On each page, Closest match is the close match nearest the original in price, and Lowest price is the cheapest swap. We compare published specs, retailer listings and reviews; we don't test products ourselves.
A cheaper product is cheaper for a reason. Each swap says what you give up, like weaker noise cancelling, a smaller screen or a shorter warranty, so you can decide if the savings are worth it.
Prices are typical US prices from retailer listings and price trackers, last checked October 2026. They are not live Amazon prices, which change often. When a price couldn't be confirmed, the page says “Check price on Amazon” instead of showing a number.
