Scentra

Fragrance is the one aesthetic choice most people make blind. Scentra teaches you to name and compose your own scent signature instead of borrowing a brand's. A free 12-question sensory quiz scores your taste across eight olfactory families; a paid report gives you your full profile, note pyramid, wear-and-test guidance and a neutral shortlist of houses that do your profile well. Scentra sells no perfume and takes no brand money, so its answer describes your nose — not a shop's inventory.
