Review: ⭐⭐⭐⭐⭐ Soft, Shiny, and Frizz-Free Hair - BioSilk Silk Therapy is one of the best leave-in treatments I have ever used. It leaves my hair incredibly soft, silky, and shiny after just one application. It helps control frizz, makes detangling easier, and does not leave a greasy feeling when used in the right amount. The fragrance is also pleasant and long-lasting. I love that it can be used on both hair and skin. This is a high-quality product that makes my hair look healthier and well cared for. I will definitely purchase it again.
Review: Best for bleached hair - Amazing as always. Perfect for bleached hair. It brings back a soft feel and takes away the look of dry texture without leaving greasy looking residue. I still have not found a comparable product to treat my bleached black hair. It keeps it from breaking and allows me to brush it without tons of breakage. It has a subtle scent that refreshes in between washes and keeps my hair from tangling too much.

## Questions & Answers

**Q: Is this product 100% authentic?**
A: After seeing this question, a further investigation was made and a comparison with the one from a local beauty shop definitely indicates that it is thinned out and not the “real thing”, not 100% authentic, in my opinion.

**Q: Why is this 17.99 and same item is $34?**
A: >> Why is this 17.99 and same item is $34?

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.

### ⭐⭐⭐⭐⭐ Dime size is all you need for AMAZING, SMOOTH, SPLIT ENDS CLOSED results!
*by L***R on June 4, 2026*

This stuff is absolutely amazing! My hairdresser had used it in me in my 20's and not until recently had I used it again. A friend had purchased this for me for my birthday and I can't believe what a dramatic change it does to my fine, limp hair. Just a dime size will do (wait til your hair is damp but not wet for best results otherwise you end up with the greasy look). It might seem a bit pricey, but a little goes a long way. It will give you shine like no tomorrow plus close any split ends that you may have. I'm absolutely in love with this product and am so happy to be reunited with it once again. Highly recommend to everyone regardless of texture or hair follicles. It really IS miracle cure and an instant styler for all.
