How to Use
Rated 3.95 out of 5 stars
I love this product. I bought it while it was on sale (buy 2 get 1 free) so I was able to stock up! It's easy to use and it doesn't leave any residue or add any weight to your hair. I am in the process of getting my hair back to a healthy point so I do have some breakage that causes "fly-aways" but this helps to tame some of them down while protecting my hair when I do blow dry, flat iron or curl it with my hot tools. It also smells great, not an over powering scent just a light clean scent. I think I may come back to do another review on this stuff once my hair is back in tip-top shape but since most of my fly-aways are tamed I would say this will be a 5 star review once my hair is doing better!
The side of the bottle says to use this on dry hair, which I have tried, and I have also tried it on wet hair. It goes on with the same consistency as super strong hold hairspray--It's EXTREMELY sticky. I have very fine thin hair, but I have a lot of hair. I still do not like how much I have to comb through my hair and pull on my hair to get my hair soft and separated before I straiten it. It's even worse on wet hair, since I have to blow dry it. After my hair is straightened, however, I still have a small amount of frizz (which I tame with a small amount of leave in conditioner and spot treat) I do like the weight and texture it adds to my hair, and it lasts all day, even in the coastal Virginia humidity. But does the lasting quality and smell of this product really outweigh the amount I have to pull on my hair to get it un-stuck? Not too sure about that...

Felt like flat ironing with hairspray

I use this product before I blow dry my hair. I use a rounded brush and my hair is soft and smooth when finished.
Teresa from Houston
Left hair stringy and a bit tough. Will stick to chi hair shine spray. It locks in moisture with a bit of shine and you can run fingers through hair.
Linda from Saint Augustine, Fl.
It's for use on wet hair, and I had high hopes, but it dried my hair out.
Nina from Gulf Shores, Ala
I use it to protect my hair when I straighten it.

I used Biosilk as a heat protectant before flat iron. It was easy to use, and provides lots of SHINE!!
CV from Olympia, WA
Bought this product because I am using a 450 degree flat iron and really needed protection Also I need a product that will help my curls stay when using my wand. Found that this product made my hair so shiny and soft! Super easy to style with too! I use it as direction sectioning my hair, spray throughout, I then brush it so that it'll spread all through my hair, and then style. It smells sooo good and I love how it feels.

My hair can get dry in winter and this helps from trying my hair when blow drying or flat ironing.
Hannah from Columbia, MO
I have extremely processed very curly hair. I used the silk drops from this line as my heat protectant for years, and decided to go for an ACTUAL heat protectant. The drops made my hair feel soft and nice, thought it probably didn't protect it from heat too well, but these made my split ends ball up and my hair stuck together. I had to brush it out after every pass with a straightener. Definitely not the best for my hair. Maybe if your hair is already super healthy and you just need it to make a quick pass with a heat tool, it will work. Not for people with already damaged hair though. I switched to the Redken Iron Shape 11 and it's doing much better.

Product is not conditioning. It leaves your hair feeling course once dry. Complete opposite reason why I purchased it.
Shelbs from Indianapolis, IN
Very light weight. Adds that extra smell good scent before protecting your hair
Krys from Shawnee,OK
Easy to use
Momma Nead from Lancaster, OH
I use heat to style my hair everyday. My hairdresser recommended this product to me and since I've been using it, I have far fewer split ends and other damage to my hair. Absolutely recommend it.
keywin from Washington state
When my perm is growing out too much I use this product when I am curling my hair with a curling iron. It protects my hair and also keeps the curl in much longer.

I generally like BioSilk products but this makes my hair stiff and difficult to comb through.
Amy from Virginia Beach, Virginia
Kate from Los Angeles
My fine color treated hair is dry at the ends, and the flat iron makes it worse. This protects and smooths, and doesn't leave the hair sticky or crisp.
I curl or straighten my hair every day. This product has helped cut down on heat damage to my hair, that's for sure. I like it better than other heat protection products I've tried in the past. It doesn't leave my hair stiff or sticky.

I love this product, it protects my hair and it smells AMAZING!
Ana from El Paso, TX
It is to watery and frizzed my hair rather than help to straighten my hair smoothly.
Randicandi from Chicago, il
I used it on wet hair as described. When I tried to comb my hair it was so stiff and hard from the product the combination wouldn't go through it.
Elle from Upstate, SC
This helps my curly hair to dry quickly and with less frizz.
