Luxury Shampoo Campaign Poster Prompt

Create a hyper-realistic luxury product campaign poster, square 1:1, for a shampoo bottle carrying only a generic [BRAND] placeholder label. Stage the bottle as the undisputed hero: centered, tall, and gleaming, with fine water droplets on the glass, soft silk-like waves of hair flowing around it, and a backdrop of refined, muted luxury tones. Use premium studio lighting with gentle reflections and a high-gloss finish. The composition must feel like a flagship beauty campaign — expensive, clean, and instantly desirable — with no real brand name anywhere on the label.
