How it works
Hair Shine first isolates uncovered hair with a six-class, face-anchored portrait mask checked on both the original and mirrored photo. For each detected hairstyle, it measures the source luminance range and local strand detail, then lifts only highlights that already exist inside the strong-confidence hair core by at most 18 LAB luminance units. Low-confidence feather pixels are excluded to prevent a bright background edge from becoming a halo. It does not draw glossy streaks, recolor hair, synthesize texture, or regenerate the face. The result is a lossless PNG, and every pixel outside the verified highlighted-hair mask is copied unchanged.
