I just finished a bottle that I was working on for 10 yrs and bought a new one. The old bottle worked and smelled just as good over the 10 yrs as it did the day I first bought it. I wouldn't be concerned with an exp date for this stuff. **Q: Does it offer thermal/heat protection for styling** A: Hi Archie and thank you for your inquiry. This product does indeed offer thermal/heat protection for styling as well as protection from Heat, UV, cold, and pollution. Thank you!
