Olaplex No.6 Bond Smoother Leave-in - 3.3 Oz and 450°F Protection

Olaplex No.6 Bond Smoother Leave-in is a 3.3-oz styling cream for damp or dry hair, with heat protection up to 450°F and frizz control for up to 72 hours. The formula is designed to smooth, soften, and lightly hydrate hair while helping define air-dried styles.

Formula and Size

The US retail listing identifies the product as a 3.3-oz leave-in styling cream and lists a regular price of $32.00 as of 09/22/2026. The 3.3-oz size and $32.00 price place it in the premium leave-in styling category.

Its highlighted bond-building ingredient is Bis-Aminopropyl Diglycol Dimaleate. The ingredient list also includes dimethicone, cetearyl alcohol, panthenol, sunflower seed oil, grape seed oil, aloe leaf juice, and coconut oil. Sephora lists the 3.3-oz formula and highlighted ingredients as vegan, gluten-free, and cruelty-free.

How No.6 Is Used

Olaplex describes No.6 as an out-of-shower styler that can be used on all hair types and textures. The brand's product information says it can be applied to damp hair before styling or used with other stylers.

The formula is positioned for blow-dried and air-dried looks rather than as a rinse-out conditioner. Olaplex lists 450°F heat protection and up to 72 hours of frizz control for the product.

Position Among Leave-ins

Compared with a conventional rinse-out conditioner, No.6 stays in the hair and combines conditioning ingredients with styling claims. Its 3.3-oz package is smaller than many larger salon-size treatments, while its airless-pump format is intended to dispense a concentrated cream.

The formula suits people seeking smoothing, frizz control, light hydration, and heat protection in one leave-in step. The presence of silicones, fragrance, and multiple conditioning agents gives the product a richer styling profile than a lightweight water-based detangler.

Best Fit for Hair Routines

No.6 is most closely placed in the premium leave-in styling cream segment. The clearest use case is hair that needs smoothing before blow-drying or additional control during air-drying, especially when a user wants a styling product rather than a rinse-out treatment.

The product's documented strengths are its 3.3-oz size, 450°F heat-protection claim, and up to 72 hours of frizz control. Its concentrated cream texture and silicone-containing formula make it less aligned with routines seeking a weightless, silicone-free leave-in.
