Transform only the main subject(s) in the user-uploaded image to have a clean, modern bob hairstyle with smooth texture and natural volume, cut around chin to shoulder length with slightly inward ends. Change the hair color to golden blonde, a warm, shiny gold tone with natural highlights and a soft glow, looking realistic and refined. Do NOT alter the hair or appearance of any background people — they must remain exactly as in the original image. Keep all facial features, expressions, skin tone, clothing, body proportions, lighting, and background exactly the same, without distortion or change. All people remain in the exact original position with no body movement and identical posture.
