How it works
Hair Volume first isolates uncovered hair with the same six-class, face-anchored portrait mask used by Hair Color. It then expands the existing hair texture by a small, intensity-controlled amount—up to 14% horizontally and 8% vertically—and permits new pixels only where the model independently identifies surrounding background. Face skin, body skin, clothing, and accessories are forbidden destinations. The tool never generates a new face or hairstyle, returns a lossless PNG, and copies every pixel outside the expanded hair silhouette unchanged.
