Unwritten Hey Genie! Define & Shine Styler 100ml

A multitasking leave-in styler that goes two ways depending on how you dry it: comb it through and blow-dry for a smooth, glossy finish, or scrunch and air-dry to bring out natural curl and wave. It's for people who would rather own one styler than four.

What's in it

• Sodium hyaluronate and hydrolysed hyaluronic acid — humectants that hold water in the strand, which is what keeps frizz down.
• Polyquaternium-69, polyquaternium-53 and polyimide-1 — styling polymers that give definition and a flexible, smoothing film.
• Caprylic/capric triglyceride and triolein — light emollients for slip and shine.
• PVP — a film-former that helps a style hold its shape.

How to use it

Work a small amount through damp hair, concentrating on the mid-lengths and ends. Blow-dry for smoothness, air-dry for texture. Comb it through evenly before straightening. A very small amount smoothed over dry hair will settle flyaways.

Worth knowing

It's a styler rather than a treatment — it changes how hair behaves on the day rather than its underlying condition. Safe on colour-treated hair. Use a light hand on fine hair, as the emollients build up if you over-apply.
