Create a realistic, natural-looking video using the original image as the exact reference. Keep the model's face, facial features, skin tone, eyes, expression, hair color, haircut, clothing, body proportions and the entire salon environment exactly unchanged. Do not alter her identity or appearance. The model is proudly showing her new short haircut. She gently moves her head from one side to the other, slowly turning her face to reveal the haircut from different angles. Her movements should be subtle, elegant and natural, as if she is presenting her new look in a real hair salon. Let the hair move naturally with the head movement, showing the layers, shape, texture and short length of the haircut. Maintain realistic individual hair strands and natural movement. Keep the camera mostly stable with a very subtle professional camera movement. Natural salon lighting, realistic skin texture, authentic photographic appearance, smooth motion, professional hair salon promotional video. Do not change the face, do not change the haircut, do not change the hair color, do not change the clothing, do not change the background, do not add people or objects, do not distort the face or body, and do not create extra limbs or unnatural movements.
