A commercial haircare product advertisement poster set against a deep blue aquatic studio background with floating water bubbles and rich foam. 

In the center, two hands covered in rich white lather and soap suds hold a sleek white-and-blue nourishing shampoo bottle vertically. The bottle features a clean label reading "DEEP NOURISH • INTENSE REPAIR SHAMPOO" with a golden moisture droplet icon and water drop condensation. 

The right side features:

1. Bold white typography reading "100% DEEP NOURISHMENT & SHINE" above subtext "ADVANCED HYDRATION FORMULA".

2. Four circular feature icons labeled: "Repairs Damaged Hair", "Deep Moisture Lock", "24-Hour Smoothness", and "Dermatologically Tested".

Studio product lighting, crisp water refractions, rich soap bubble textures, 8k commercial render. [Reference Image Rule: If I upload a product bottle photo, replace the shampoo bottle with my uploaded product while preserving the soapy hands, water splash effects, feature icons, and commercial ad layout. If no photo is uploaded, generate the full scene directly.] --ar 4:5
