Traditional face swap has a fundamental limitation: it keeps the target person's hair. If the source person has blonde hair and the target has black hair, a face-only swap produces an odd result—the right face with the wrong hair. Head swap solves this by replacing the entire head region. The AI detects the head boundary (including hair, ears, and cranial shape), maps the source head onto the target's body, and blends at the neck boundary. The result is a natural-looking composite where the source person's complete head sits on the target's body with matched lighting, skin tone, and perspective.

Head Swap vs Face Swap: When to Use Each

Face swap keeps the target's hair and head shape and only replaces the face—eyes, nose, mouth, jaw, and skin texture. This is the right choice when source and target have similar hair, or when you specifically want to keep the target's hairstyle. Head swap replaces the full head: face, hair, scalp, ears, and head contour. Use head swap when the source has distinctive hair (different color, length, or style), when face swap leaves a visible seam at the hairline, or when you want the complete identity of the source person in the output. Both modes are available for images and video. For most creative and content creation use cases, head swap produces more convincing results because it eliminates the hair mismatch problem entirely.
