Silky Hair Color Transformation

Create a realistic 15-second premium beauty advertisement. A young woman with long, slightly dull hair stands in front of a modern bathroom mirror. She smiles softly and applies a rich, creamy hair color evenly from roots to ends using a brush and gloves. Smooth close-up shots capture the luxurious texture of the product and the careful application. Transition with a soft cinematic glow. The final reveal shows her walking confidently in natural golden sunlight, flipping her silky, smooth, vibrant, freshly colored hair with a radiant smile. Her hair looks healthy, shiny, and full of life. Elegant slow-motion shots, premium cosmetic commercial style, ultra-realistic 4K, soft lighting, shallow depth of field, luxury beauty brand aesthetic, no dialogue, no text, emotional background music only.
