Dry scalp vs oily scalp: what each looks like on camera.

Dry and oily leave close to opposite visible signatures, yet people routinely guess wrong about their own scalp — usually because they're judging by feel, by one bad hair day, or by whatever their last shampoo bottle promised to fix. On camera the split is more legible: dryness tends to read as a matte, duller surface with fine flaking at partings and edges, while oil reads as reflective shine along the part and crown, with hair that clumps and flattens. A guided four-angle scan reads those signals where the photos actually show them — as appearance, not as a scalp-type diagnosis — and saves the picture as a dated baseline. That matters because the honest answer can also be 'neither, today' or 'different zones, different stories,' which is exactly the nuance a one-word label flattens.
