@image 1 as model, @image 2 as exact product.
Authentic UGC tutorial/how-to video, shot on a phone, mostly propped with natural handheld for the demo — a model-type young woman in her early-to-mid 20s with mid-length dark hair (damp at the start, just washed), striking light eyes, light freckles, fresh natural skin and soft makeup, calm friendly knowledgeable teacher energy, in a soft casual knit or robe. She's in a stylish modern bathroom with a glass shower in blue vertical-stacked tile, soft beige walls, a marble double-sink vanity, brushed-brass fixtures, a white hand towel, cylindrical sconces and a sprig of eucalyptus, soft natural daylight and warm sconce light. The hero product (matching @image_1) is an amber glass dropper bottle with a black pipette cap and clean white label with the brand name, scalp-serum wording and a small green root emblem. With damp hair she holds up a section and a towel to the lens with a knowing look — "This is why your hair feels dry after every wash." She demonstrates the wrong way, roughly scrubbing her wet hair with the towel and yanking a brush straight down from the roots, shaking her head no — "Stop scrubbing with a towel and brushing from the roots." She holds up the amber serum bottle, squeezes the dropper to apply it generously along her scalp and lengths, then presses and pats it in gently with her fingertips — "Apply this generously, press it in gently, don't rub it away." She lets it soak a beat, then gently combs through starting at the ends and slowly working upward with no tugging — "Let it soak two minutes, then comb from the ends up." Finally she runs her fingers through smooth, soft, shiny hair, gives it a light flip, then holds the serum bottle up clean to the lens with a happy smile — "And that's how you get soft, shiny, healthy hair." Natural room tone with light hair and dropper sounds, no music, the amber bottle staying the hero, phone facing her directly so the mirror is never used or reflected, photorealistic, no text overlays.
