the prompt

A realistic 15-second vertical beauty advertisement video of a young East Asian woman with long dark brown hair in a bright modern bathroom with wooden walls, large window with blinds, and natural sunlight streaming in. She wears a simple beige ribbed tank top and has natural glowing makeup with soft pink lips. Start with her holding a frosted glass spray bottle with a gold pump and white label, smiling brightly at the camera while looking slightly to the side. On-screen text appears: “My Hair Refresh ✨”. She speaks enthusiastically: “If your hair looks dry and messy in the morning, try this: just a little serum makes such a difference!” She pumps a small amount of white serum onto her palm, then runs her fingers through her hair, applying the product. Text changes to “Smooth & Frizz-Free ✨”. She flips and smooths her hair, showing the transformation. Next, she runs both hands through her now shiny, smooth, silky hair while smiling and speaking: “Look how smooth and shiny my hair looks now!” Text changes to “Fresh Hair Finish ✨”. She continues flipping and tossing her hair playfully, looking happy and confident. Final text appears: “Try It ✨”. She holds the bottle up again, smiling at the camera, and says: “This is definitely staying in my morning routine.” Soft natural lighting, warm golden hour sunlight, high-quality realistic skin texture, cinematic beauty commercial style, smooth camera movements, vertical 9:16 format, 15 seconds duration.
