KEVIN.MURPHY Killer.Waves Wave Enhancer for Fine Wavy & Curly Hair — Weightless Frizz Reduction, 150 mL

KEVIN.MURPHY KILLER.WAVES is a lightweight wave enhancer that defines and revives fine wavy or curly hair while reducing frizz and adding shine.

Designed specifically for fine textures that struggle to hold shape, KILLER.WAVES sculpts natural waves and curls without weighing strands down. The formula layers easily under styling products, enhances elasticity, and helps hair look polished and resilient for day-to-day wear. Sulfate- and paraben-free, it aligns with KEVIN.MURPHY’s salon-quality approach that respects both hair and the environment.

How does KILLER.WAVES improve natural waves and curls?

This product boosts definition by coating strands with a light, flexible formula that supports curl pattern without stiffness. It enhances movement and separation so waves appear more pronounced and curls keep spring and bounce through the day.

• Lightweight film that defines without heavy residue
• Improves curl elasticity for better spring-back
• Leaves hair soft to touch, not crunchy

Can it control frizz on fine hair without flattening volume?

KILLER.WAVES targets surface frizz and humidity-driven flyaways while preserving lift at the roots. Because the formula is weightless, it tames frizz without compressing the natural volume that fine textured hair needs.

• Humidity-resistant feel for smoother strands
• Non-greasy finish keeps hair airy and light
• Works well layered under volumizing or texturizing products

How do I use it for best results on damp or dry hair?

Apply a small amount to damp hair, scrunching from mid-lengths to ends to encourage wave formation; diffuse or air-dry. On dry hair, use sparingly to refresh and reactivate definition without causing buildup.

• Use a pea-sized amount for short hair, more for longer lengths
• Scrunch and let hair dry naturally or diffuse on low heat
• Reapply lightly to dry hair to revive second-day texture

Is KILLER.WAVES suitable for color-treated or damaged fine hair?

The sulfate- and paraben-free formulation is gentle enough for color-treated and chemically processed fine hair. It supports manageability and shine while avoiding harsh surfactants that can strip treated hair.

• Safe for color-treated and chemically styled hair
• Helps reduce the appearance of dryness and roughness
• Fits into a restorative routine without interfering with treatments

Who is this for: KILLER.WAVES is ideal for anyone with fine, wavy, or curly hair who wants defined texture, frizz control, and weightless hold. It suits people seeking an everyday enhancer that enhances natural shape without stiffness, as well as stylists looking for a reliable product to layer with other KEVIN.MURPHY styling treatments. If you prefer formulas free of sulfates and parabens and want a salon-quality finish at home, this 150 mL wave enhancer is formulated for your routine.
