15-second 4-shot short video, no text/subtitles, 4K ultra-realistic, seamless shot transitions, clean clutter-free frames, extreme before-after hair contrast. Shot 1: Extreme close-up of Caucasian female scalp (no face), greasy shiny roots, flat limp strands clinging to scalp, visible large dandruff flakes on scalp/hair parting, cool soft bathroom glow, hyper-realistic texture, highlight oily-dandruff distress. Shot 2: First-person POV, hands gently rub triangular soap under showerhead, instant thick dense light green foam, fluffy non-collapsing bubbles, water droplets on hands, bright shower lighting, natural rubbing motion, realistic foam dynamics. Shot 3: Medium back shot, female under shower, hands evenly lather foam through full hair, hair fully wrapped in foam, warm water streaming down hair/back, smooth scalp massage movements, warm bathroom lighting, transparent delicate foam-water texture. Shot 4: Medium shot, bright natural bedroom light, female facing camera, freshly dried hair—fluffy voluminous shiny, oil/dandruff-free scalp, light non-frizzy texture; one hand holds triangular soap clearly to camera, other hand casually runs through hair, fresh healing high-end visual style, emphasize oil-control dandruff-removal smoothing effects.
