Making this hair color spray product ugc ad with Seedance 2.5 via @Flovaai

English prompt

Create a 30-second ultra-photorealistic UGC-to-commercial hair color spray advertisement. The first 25 seconds should feel like authentic creator-shot UGC, while the final 5 seconds must transition into a premium professional product commercial hero shot. A young woman has naturally deep black hair at the beginning. After applying the hair color spray, the sprayed hair becomes clearly light brown. The black-to-light-brown difference must be obvious and visually satisfying. 0–4 SEC — UGC HOOK Real young woman filming herself with a modern smartphone in a realistic bedroom. Handheld front-camera feel, natural daylight, subtle camera shake and authentic facial expression. She touches her clearly black hair and says: “I wanted lighter hair…” She looks at herself in the mirror. 4–8 SEC — PRODUCT DISCOVERY She turns toward her bedroom dressing table. The hair color spray is clearly standing on the dressing table. She reaches for it and picks it up naturally. As soon as she lifts it, the smartphone camera briefly autofocuses sharply onto the spray, making the entire product clearly visible and recognizable. Realistic bottle/can material, nozzle, cap, label, reflections and printing. She says: “…without permanently dyeing it.” 8–13 SEC — PRODUCT APPLICATION She holds the spray clearly in her hand, then separates a section of her black hair and applies it. Show a realistic fine aerosol mist leaving the nozzle and settling onto the hair. The sprayed hair changes realistically from deep black to light brown. The transformation must happen through believable color coverage, not glowing or magical effects. 13–18 SEC — CLEAR TRANSFORMATION Close smartphone shot of the hair. Show untreated deep-black hair beside the newly light-brown hair so the color difference is extremely obvious. She gently moves the hair with her fingers under natural daylight. She reacts naturally: “Okay… that is actually a huge difference.” 18–23 SEC — UGC RESULT Mirror selfie showing her finished light-brown hair. She turns her head naturally, showing the color from different angles. She smiles and says: “I actually love it.” The footage remains authentic UGC with natural imperfections. 23–26 SEC — FINAL UGC PRODUCT MOMENT She holds the spray beside her newly light-brown hair and looks into the camera. She says: “Just spray and switch up your look.” She lowers the product slightly. 26–30 SEC — PREMIUM COMMERCIAL PRODUCT HERO SHOT Hard transition from UGC footage into a clean professional product advertisement. No woman visible in this final shot. Show the hair color spray alone as the hero product, standing upright on a clean premium surface. Create a beautiful realistic commercial product-photography setup with a soft neutral background, subtle depth of field, controlled studio lighting, realistic product shadow and premium reflections. The camera slowly pushes toward the product. The product must be large, centered and extremely sharp, with the packaging, cap, nozzle, label and every visible detail clearly readable and professionally presented. Place the product beside a small visual indication of the black → light brown transformation, such as realistic strands of black hair transitioning into light brown hair, subtly arranged behind or beside the product. Leave clean negative space around the product for advertising copy. Final frame should look like a professional beauty-brand product poster / end card, not UGC. Suggested minimal on-screen copy: INSTANT HAIR COLOR BLACK → LIGHT BROWN SPRAY • STYLE • GO Keep the product as the dominant visual element. IMPORTANT The final 4 seconds must feel like a real commercial product hero/end card, with a completely different level of polish from the preceding UGC footage. No girl in the final hero shot. No hands holding the product. No messy bedroom. #flovacpp #Flovaai
