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! Beautystoredepot **Q: Do you use this after applying hair moisturizer, or before? And do you wash the treatment after you applied it? Or just leave it as it is? Thx** A: You use this drops after your conditioner ,towel dry your hair apply 2drops on your hair and comb it through.dont wash it , leave it on your hair,your hair is not going to be oil.it goes right into the hair . It's good for freezer hair,detangle hair also to make it shine it, without pulling the curls,.good for all types of hair **Q: Can anyone please explain how to use this product. Can it be used on dry hair. Any help will be appreciated...thank you!** A: This can be used on dry hair and dry skin. It is not greasy. It is very light. I would not use it on wet hair or skin.
