Prompt: “Edit the uploaded portrait to preview a wearable cinnamon-copper hair color with subtle darker roots and softly varied tones. Preserve the person’s facial features, skin tone, hairstyle, hairline, and individual flyaways. Change only the hair color, retaining realistic strand texture, natural highlights, and existing shadows. Match the original lighting and leave clothing and background untouched. The result should resemble a professional salon color photograph, not a wig or beauty filter.”
