Olaplex No.5 Bond Maintenance Conditioner - 250 mL Formula

Olaplex No.5 Bond Maintenance Conditioner is a concentrated rinse-out conditioner for medium to coarse hair. The US full-size bottle contains 8.5 fl oz/250 ml, and the formula is positioned for hair affected by dryness, damage, split ends, and breakage.

Concentrated Conditioner Formula

Olaplex describes the conditioner as highly concentrated and designed to strengthen, nourish, ease detangling, and smooth hair in one wash. Its highlighted ingredients include bis-aminopropyl diglycol dimaleate, panthenol, and glycerin, while the ingredient list also includes cetearyl alcohol, cetyl alcohol, and conditioning agents.

The formula is listed as vegan and cruelty-free, with no parabens, formaldehyde, phthalates, mineral oil, sulfates SLS and SLES, or coal tar. Sephora also identifies it as suitable for straight, wavy, curly, and coily hair textures, while the stated hair-type focus is medium and thick hair.

Application And Documented Results

Olaplex recommends applying No.5 after shampooing, working it through the mid-lengths and ends, leaving it on for 1-3 minutes, and rinsing well. The manufacturer specifies up to 50 applications for the 250 mL size, based on an average application size of 5 mL.

Olaplex reports a 91% increase in hydration, 91% easier detangling, and 66% less breakage instantly in testing with No.4 Bond Maintenance Shampoo and No.5 Conditioner used as a system. Those figures describe the tested routine, which also included No.9 Bond Protector Nourishing Hair Serum before styling.

Price And Category Context

The US full-size price is $34.00 as of 09/23/2026. Sephora lists the same 8.5 fl oz/250 ml size at $34.00, while smaller and jumbo sizes are sold separately.

Compared with a basic rinse-out conditioner, No.5 places more emphasis on bond-building technology, concentrated application, and damage-related hair concerns. Its practical fit is strongest for medium or thick hair that needs conditioning and detangling; the one-to-three-minute contact time also separates it from leave-in treatments and masks.

Best Fit For Damaged Hair

Olaplex No.5 Bond Maintenance Conditioner is a personal-care conditioner with a 250 mL US package, a concentrated formula, and documented use for medium to coarse hair. The product's limits are equally specific: the reported clinical figures come from a multi-product system, and No.5 is a rinse-out conditioner rather than a standalone styling product.
