Step 3 Choose Your Curl Styler

You do not necessarily need a heavy application of both styling products at the same time. Choose according to the finish and level of hold you want.

KILLER.TWIRLS – Choose for softer hold, hydration, natural texture and an easy air-dried finish. KEVIN MURPHY specifically describes it as a soft-hold, humidity-resistant leave-in styler.

KILLER.CURLS – Choose when you want stronger curl activation, definition and anti-frizz control with greater hold and elasticity.

For additional control, small amounts can be layered according to your curl type and styling needs.

Scrunch curls gently upwards to encourage their natural pattern.

Allow to air-dry or use a diffuser.
