I purchased this product at Costco years ago and it was a good deal. I have used other products like argan oil and refer them over the Bio Silk. I find that the Bio Silk leaves my hair feeling soft but very oily ven when using the correct amount. I also find that I when I don't wash the 2nd day and use a dry shampoo that the effectiveness of it is cut down when I already have Bio Silk on m hair.

This product is a bit expensive but smells great and works great.

I have been using this product for years now.Although someone in the salon told me that it dries out your hair, i still think this product works well and it gives me that silky and smooth finish.

This stuff is great on hair and as well for skin no oily residue have bought it for years lasts for ever

My hairdresser used it on my hair after my last visit. I had to have some for myself, so I bought some. I love the smell and it made my hair so soft and shiny and you don't need a lot of this product either, so it does last.
I use it daily. It costs a little more but it is definitely worth it. Amazing product, I am hooked.

I started using biosilk when I was on a trip to Florida about 13 years ago. I saw it in a salon. My hair is very dry frm blow drying it all the time.. I love to try different products and see if they prove wat they say. Right away I love the smell. I used it before and after blow drying and it made my hair smell n feel amazingly. I really loved it and had been using it ever since. I highly recommend this product to be added to all men n women hair product collection! Thank u!

Okay this product to me is magic. i just love it!
i get mine at Costco so i think the price isn't so bad.

The smell the texture, the smoothness... everything about it is just amazing!
i even use it on my arms Now i don't know if there is supposed to be any other virtue except smoothness but i really do love this product

And a little goes a long way

Good product for hair. Only problem I had was that my skin reacts to this product.

Biosilk is a staple in my bathroom shelf. I have natural curly hair ... I use this product when I straighten with a hair iron. This leaves my hair super straight, shiny, silky soft and the smell is fantastic. Love this serum and have recommended to my friends and family.

I think after using Biosilk Silk Therapy, I've pretty much tried the vast majority of leave-in hair serums on the market (well, except for It's a 10).
I only intended on trying out Biosilk Silk Therapy because quite some time ago one blogger commented that she loved Biosilk as a leave-in serum. Hmmm well I have to say I am disappointed with the product and that it's just mediocre at best. It doesn't stand out from a crowd of others on the market - it does a good job as a detangler after washing my hair but any other serum will do that. Once my hair air dries with this stuff in it, it doesn't seem to have any lasting shine or manageability. I much prefer CHI Silk Infusion or my favourite, HANA Shine Shield Thermal Protectant (both which I reviewed on Chickadvisor and on my blog).
