Review: Great product if it's authentic. Makes my hair silky, but thin-looking. - The picture shows shampoo. The title says Cure. Not sure what you're buying here, but when I purchased, it was shampoo. I have used all three products: shampoo, conditioner, Cure. Since some reviewers have claimed to receive fake products, I no longer purchase online, only in local shops. This is my review: I started using Silk Therapy Serum many years ago after one hairdresser used it on my hair. It’s expensive, but so worth it. My hair is long, thick, and wavy in a very unmanageable way. It used to be silky and strawberry blond, but as I’ve aged the color has dulled so I highlight it. That has caused a texture change and my hair is more like cotton than silk. I’ve longed for the silky hair of my youth, but it had eluded me for decades. After seeing a commercial for L’Oreal Elvive Total Repair 5 I started using the shampoo, conditioner and Protein Recharge. Honestly, my hair hadn’t looked that good in years. I love it. I also put the Biosilk Silk Therapy Cure Serum on my misbehaving ends and it helps tame them into submission. Somewhere along the way, I decided to buy the Biosilk Shampoo. I tried it, but was annoyed at two things. First, it seems that I needed twice the amount of shampoo I normally use, and two, it took a ton of strength to squeeze the shampoo out of the bottle. Very irritating. So mostly the bottle just sat under the cupboard. Until recently. I needed more Serum, and I ended up purchasing a set that included the shampoo & conditioner with the serum, so I decided to try all three products together and see the results. I was truly impressed. The conditioner made the difference. My hair was the silkiest I’ve ever seen. It was cool to see my hair look like the silky, flowing hair of models on TV. (I blow-dry my hair over a large round brush.) But the one thing I didn’t like is how flat my hair was compared to the fullness I get from the L’Oreal Elvive. The results are very similar. Both make my hair silky and manageable, but the BioSilk may have the edge there, but the L’Oreal gives me the fullness I need and want. I’ll probably use L’Oreal most of the time (with the Silk Therapy Serum on the ends), and use the Biosilk products on special occasions when I don’t care if I have thin-looking hair until my next wash. I now buy locally to ensure I am getting a genuine product.
Review: Terrific Hair Results - I cannot say enough good things about this product. BioSilk Silk Therapy can make the most damaged hair feel silky smooth. And it's great for tangled and knotted hair. It only takes a small amount. You definitely don't want to apply too much, because it will make your hair oily. And there's a little bonus. Once you've finished applying it to your hair, rub your hands together like you do with a lotion. It will make them soft as well.

## 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

**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.
