• Anyone who regularly blow-dries or uses hot tools (flat iron, curling iron) and wants a heat-protectant step that also adds shine and light body.
• All hair types/lengths per the brand; not restricted to a specific texture.
• Consumer retail product, no professional mixing required — straightforward pre-styling spray.
• Best suited to people who want a multitasking prep spray rather than a separate heat protectant and separate shine serum.

Trilliant earns its "multitasking" label honestly: the same bottle works differently depending on when you use it — on damp hair before blow-drying it's about body and brilliant shine, and used sparingly on dry hair right before a flat iron or curling iron it becomes the heat-protection step. For anyone who currently uses a separate heat protectant and a separate shine spray, this collapses that into a single pre-styling product built around Sebastian's rock-crystal shimmer complex.

• Shake well before every use to blend and activate the Trilliant shimmer complex.
• For body and shine: spray on damp hair just before blow-drying.
• For heat protection: use sparingly on dry hair right before styling with flat irons or curling irons.

• Pros: genuinely dual-purpose — one spray covers pre-blow-dry body/shine and pre-hot-tool heat protection; lightweight, won't weigh hair down; adds noticeable shimmer/shine without an oily finish.
• Cons: needs a firm shake before every use since the shimmer complex separates; it's a prep/finishing spray, not a leave-in conditioning treatment, so it doesn't substitute for a deep conditioner on damaged hair; alcohol content means heavy, frequent use could be drying for very fine or already-dry hair.
