Review: This product is amazing! The ingredients won't cause harm to your hair! - BioSilk Silk Therapy has quickly become one of my favorite leave-in treatments! After just one use, my hair feels noticeably softer, smoother, and has a beautiful shine. It helps tame frizz, makes brushing and detangling much easier, and leaves my hair feeling moisturized without a heavy or greasy residue when used sparingly. I also really enjoy the light, pleasant fragrance, which lasts throughout the day. Another great feature is that it can be used on both hair and skin, making it a versatile product. Overall, I’m very happy with the results. My hair looks healthier, feels silky, and has a gorgeous shine. This is definitely a product I would purchase again! Review: Love this product - I have ordered BioSilk from this seller two times now. I am very happy with this seller. As many people know, there are a lot of fake BioSilk products on the market. I've accidentally bought fake products multiple times. It's hard to know if the stuff sold at Marshall's or TJ Maxx and places like that are truly BioSilk brand, so often times it's hard to find the real stuff. I'm not positive, but I believe this is the real deal! I have been using BioSilk my entire life. For me it doesn't cause acne, bacne, gross product build up, or oiliness like other products tend to do. I feel as though it strengthens my hair, moisturizes it and makes it shiny and soft. I have very long and thick hair, BioSilk helps keep it healthy and de- tangled. I only like to wash my hair once a week. I've tried many products that align with only washing my hair once a week. Most make it feel heavy and make me feel the need to wash it more often. With BioSilk, I can stick with my routine and only wash my hair once a week because it keeps it lightweight and not too oily. I get many compliments on my hair and attribute it to BioSilk. If you have thinner hair, use sparingly. A little goes a long way. (If you're concerned about the price, it lasts forever) Regardless, always start at the ends and work your way to the roots. Never put product in your hands and go straight to the roots, always start at the ends when it's fresh on your hands. The product also arrived very quickly and with no damage. I will buy again and again! Well worth the money! ## Features - WEIGHTLESS LEAVE‑IN TREATMENT: Silk Therapy Original infuses hair with silk proteins to repair, smooth, and protect strands without heaviness. - REPAIRS & STRENGTHENS: Helps rebuild damaged hair, prevent split ends, reduce frizz and improve shine for healthier‑looking hair. - ALL‑HAIR-TYPES FORMULA: Gentle, cruelty‑free, sulfate‑ and paraben‑free treatment suitable for straight, wavy, curly, fine or textured hair. - MULTI‑PURPOSE CARE: Use on wet or dry hair to detangle, condition, add shine, and help protect from heat and environmental stress. - BIOSILK: The quest for healthier hair is how BioSilk Silk Therapy emerged in 1986.

The wholesale price we get from the manufacturer is DEFINITELY MUCH higher than $17.99. Take a chance when you buy such items. Counterfeits are everywhere in eBay and Amazon. **Q: CN I use this on dry hair?** A: I use it only on dry hair. I have curly hair and apply it every morning and as needed throughout the day if I’m out in humid weather. It keeps it from getting frizzy and stays smooth most of the day. Just don’t put it close to your roots or it will look greasy. **Q: Why are A batteries required???** A: It doesn’t. There must have been a typo in the listing. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This product is amazing!
