Edit the uploaded portrait into a realistic straight-hair version of the same person. Preserve identity, facial structure, expression, skin tone, pose, camera angle, clothing, accessories, background, lighting direction, shadow quality, image perspective, and overall composition. Transform only the visible hairstyle: straighten curls, waves, flyaways, and frizz into smooth, naturally aligned strands with believable shine, clean ends, and a flattering shape that fits the original head, hairline, face shape, and shoulder position. Keep the hair attached naturally to the scalp, maintain realistic volume instead of making it flat, and respect visible length cues unless the source clearly requires small adjustments for a coherent straight style. Match color, highlights, root tone, texture detail, depth of field, and photo grain to the original image. Avoid changing the face, age, body, background, clothing, makeup, ethnicity, identity, or expression. Avoid plastic hair, helmet-like shapes, duplicated strands, warped ears, broken hairlines, unnatural reflections, mismatched lighting, extra people, text, logos, watermarks, UI elements, or obvious retouching artifacts. Produce a polished, high-quality straight-hair portrait that looks like it was captured in the same scene.
