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. Just my own opinion. It works best on dry hair and dry skin. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best Hair serum *by A***D on 10 February 2025* the original Biosilk serum-the best hair serum for reducing frizz and styling hair. ### ⭐⭐⭐⭐ luv it *by A***N on 25 May 2016* does wht it says nd makes hair shiner ### ⭐⭐⭐⭐⭐ Review *by M***I on 15 June 2025* Seta per capelli, prodotto eccezionale i capelli dopo le prime applicazioni cambiano del tutto il loro aspetto, morbidi vivi lucidi e profumati ## Frequently Bought Together - Biosilk Silk Therapy Cure, 5.64 oz - BioSilk Hydrating Therapy Pure Moisture Leave-In Spray, Replenishes Hair Moisture & Protects From Frizz, Sulfate, Paraben, & Cruelty-Free, 7 Oz - Biosilk Silk Therapy with Natural Coconut Oil Leave-In Treatment, Helps Control Frizz & Flyaways, Sulfate, Paraben & Cruelty-Free, 5.64 Oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/296484529-silk-therapy-serum-packaging-may-vary-5-64-ounces](https://www.desertcart.pt/products/296484529-silk-therapy-serum-packaging-may-vary-5-64-ounces) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-18*
