UGC-style shampoo commercial with handheld selfie camera aesthetic

UGC-style authentic selfie video, handheld iPhone front-camera aesthetic, vertical 9:16 format, natural daylight throughout, slight handheld camera shake for realism, no studio polish - should feel like a real customer testimonial, not a commercial. Same young woman with curly natural hair throughout, warm brown skin tone, genuine relatable energy. Video opens in a bright bathroom with soft window light: she holds up the Mielle Rosemary Mint Strengthening Shampoo bottle close to camera, black pump bottle with green label clearly visible, smiling directly at lens, talking excitedly to introduce the product. Cuts to a steamy shower scene, water droplets on glass: her hair now wet and curly, she squeezes shampoo from the black pump bottle into her palm, close-up on the green rosemary mint label and product texture, quick candid multi-angle cuts like real phone footage. Continues in the shower as she massages the shampoo into her scalp, foam building through her curls, eyes closed, relaxed genuine expression, water running down her face and shoulders. A subtle overlay graphic of a rosemary sprig with the text "Infused w/Biotin" fades in briefly. Transitions to a bright bathroom mirror selfie: hair now towel-dried, she scrunches her curls with the fresh product, hair visibly stronger and more defined, talking directly to camera with excited genuine expression, the shampoo bottle placed on the counter beside her with the green label facing camera. Final sequence moves outdoors into golden hour natural light: she walks and laughs, tossing her healthy defined curly hair with visible shine and bounce, authentic candid lifestyle feel. Ends on a final selfie shot holding the Mielle Rosemary Mint Strengthening Shampoo bottle beside her face, genuine warm smile, talking to camera. Soft text overlay appears: "MIELLE Rosemary Mint | Infused w/Biotin," closing on the bottle centered against a clean background. Overall mood: authentic, unfiltered, handheld imperfection, warm approachable color grade, natural skin and water texture, real bathroom and outdoor environments, consistent character and wardrobe throughout, no cinematic bokeh or studio lighting.
