Suited to people with frizzy, unmanageable, color-treated hair who want a rinse-out conditioner focused on smoothing rather than pure moisture repair. It's a good fit for thicker or coarser textures that frizz easily in humidity, and for anyone already using Pureology's Smooth Perfection Shampoo, since the two are formulated as a paired system. It's less suited to fine, easily weighed-down hair, since smoothing conditioners built around shea butter and heavier conditioning agents can feel heavy on finer strands.

Smooth Perfection Conditioner is worth choosing over a general-purpose conditioner specifically because its conditioning agents are selected for frizz control and manageability rather than volume or moisture alone — behentrimonium chloride in particular is a heavier-duty smoothing agent than what's used in lighter conditioners. Combined with AntiFade Complex, it addresses two things at once for colored hair that also frizzes: color retention and cuticle smoothing, instead of requiring a separate anti-frizz serum layered on top of a basic color-safe conditioner.

After shampooing with Smooth Perfection Shampoo, apply a quarter-sized amount of conditioner to the mid-lengths and ends of towel-blotted hair, avoiding the scalp. Massage through, leave on for one to two minutes, then rinse thoroughly.

For extra frizz control, follow with a Pureology leave-in or styling product from the Smooth Perfection line before blow-drying or heat styling.

What works: the behentrimonium chloride and cetearyl alcohol combination is a proven approach to taming frizz and easing wet-and-dry combing on coarse or curly textures, so the smoothing effect isn't just a marketing claim — it's the core mechanism of the formula. Pairing it with the matching Smooth Perfection Shampoo reinforces both the AntiFade and anti-frizz benefits across both wash steps instead of diluting them.

Where it falls short: richer conditioning agents and shea butter can leave fine or low-density hair feeling coated or flat if overapplied, since the formula isn't built to be lightweight. It's also a targeted anti-frizz product rather than a deep-moisture treatment, so hair that's dry but not especially frizzy may do better with Pureology's Hydrate line instead.
