Photorealistic vertical 9:16, UGC phone look at a round makeup mirror in a bright generic cosmetics store (no brand logos). A white European woman in her late 20s with brown hair runs the small rose-gold portable mini hair-styler brush from the reference image down a section of her hair — clearly showing the transformation: the brushed section is now smooth, sleek and straight and shiny, while the rest of her hair is still frizzy and wavy. Impressed, happy expression. Natural store lighting, shallow depth of field. Keep the device exactly like the reference. No brand logos, no on-screen text, no watermark.
