Sebastian Professional Dark Oil Silkening Hair Mist is a lightweight finishing spray, not a leave-in treatment, that smooths the hair's surface and adds shine as part of Sebastian's Dark Oil styling collection. It's meant to be the last step in a routine — misted onto damp hair before blow-drying for a shine base, or lightly over a finished style or second-day hair as a quick refresh.
The formula pairs a silicone (dimethicone) for slip and softness with small amounts of argan and jojoba oil, plus the fragrance that carries the Dark Oil line's signature scent. Because it works on the hair's surface rather than penetrating the shaft, it complements a separate moisture or repair routine rather than replacing one for genuinely dry or damaged hair.
