## Questions & Answers

**Q: does anyone pay attention to Biosilk"s expiration dates on the bottom of the bottle?**
A: nope. my bottle is so old that they didn't even put exp. dates on it back then.  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

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!**
