What Is It?

KEVIN MURPHY Curl Definition and Frizz Control Set is a complete three-step routine designed to cleanse, condition and define naturally textured hair.

KEVIN MURPHY specifically recommends KILLER.CURLS WASH and RINSE across curl types from waves to coils, describing the combination as designed to refine and enhance texture, combat breakage and prepare hair for air-drying.

KEVIN MURPHY KILLER.CURLS WASH 250ml

A nourishing Oat Milk-inspired curl shampoo that gently cleanses while protecting the cuticle.

The formula helps preserve strength and retain moisture, supporting healthier, shinier and more manageable curls.

Hero ingredients include Oat Kernel Extract, Castor Seed Oil and Soybean Oil, selected to hydrate, nourish and improve softness, strength and shine.

Important: Sulfate Free Shampoo

KILLER.CURLS WASH does not contain SLS or SLES in the current official ingredient list. Its primary cleanser is Sodium C14-16 Olefin Sulfonate, which is chemically a sulfonate rather than a sulfate.

So for accurate product-page wording, I would describe it as:

SLS and SLES free

rather than making a broader “sulfate-free” claim unless that exact claim appears on your local product packaging.

KEVIN MURPHY KILLER.CURLS RINSE 250ml

A nourishing conditioner designed to deeply hydrate and strengthen curls.

It helps reduce the likelihood of breakage while protecting against colour fading and refining texture for soft, shiny, bouncy and defined curls.

Hero ingredients include Oat Kernel Extract, Avocado Oil and complementary conditioning ingredients that help improve moisture, softness and manageability.

KEVIN MURPHY KILLER.CURLS 200ml

An antioxidant-rich anti-frizz curl-defining crème designed to activate and enhance natural curls.

It helps hydrate and strengthen while providing weightless, long-lasting smoothness, natural movement and curl definition.

It also provides heat protection up to 216°C / 420°F and is particularly recommended by KEVIN MURPHY for medium to coarse curly or wavy hair.

Together, the three products create:

Cleanse → Hydrate → Define

for softer, smoother and more controlled curls.
