Why You’ll love it

Style with heat and keep your hair feeling like you didn’t.

Helps reduce the look of breakage and split ends.

Leaves hair soft, flexible, and easy to brush through.

Lightweight foam absorbs quickly with no sticky or crunchy feel.

Description

KEVIN.MURPHY HEATED.DEFENCE is a lightweight leave-in foam that shields hair from heat styling damage.

This thermal protector wraps each strand in an invisible, weightless barrier to help reduce breakage and split ends. The airy, whipped texture melts into damp or dry hair, leaving it feeling soft, smooth, and easier to brush through.

There’s no sticky residue or crunch, just a natural-looking finish with flexible movement and light shine. Use it before blow-drying, straightening, or curling whenever you want to style without the stress.

Ideal for anyone who uses hot tools regularly, especially those with fragile, colour-treated, or damaged hair, it helps hair feel stronger, more manageable, and less frazzled after styling.

Directions

How To Use KEVIN.MURPHY HEATED.DEFENCE

Shake well before use.
Apply 1–3 pumps of foam to clean, damp or dry hair.
Distribute evenly from mid-lengths to ends, avoiding the roots.
Comb through to ensure even coverage.
Style with hairdryer, straighteners, or curling tools as desired.
