Smells awesome. But didn't quite work out well for me. Made my hair a little greasy at the roots and also had an allergic reaction to it. I'm sure it is a great product for others though. Different strokes for different folks .

great product yet pricey

I have the lite bottle, and I must say the best serum I've used yet. I'm not into serum that much, because of how greasy it is, but when I flat iron my hair using this product it doesn't frizz, and my hair is movable (meaning it has body, when I shake my head).

Amazing stufff. ive been using it for 7 years. makes your hair soft and shiny. just dont put to much or it was get greasy

love it makes your hair shine like the sun but its a bit pricey

Silky I use this everyday after flat ironing my hair. This leave your hair soft and silky

A little greasy at times. I use this from time to time, but I find that it can sometimes make my hair look greasy rather than silky and shiny. If I'm having a really frizzy day, it's helpful. I prefer leave-in creams to this. The smell is nice though!

Unsure.. I own this product and had it on my dresser for a long while now. Maybe it's just me maybe I'm just not using it right or something but it didn't really do much for me. It did however make my hair really shiny and I had a little less frizz but in my opinion it's a little too greasy or oily feeling, it didn't make my hair soft and I didn't like the feeling after it dried on my hair. It did work on my sister's hair though it made blow drying her hair a breeze which usually takes 2 hours because it's so thick and coarse. So its different results on different hair.

This works really well to tame my hair down, but I can't shake the feeling that it is a bit greasy whenever I put it on. It has a very nice smell and really does get rid of the frizz, but I don't like the actual texture of my hair after I put it in. It's slick, rather than soft. All in all though, if you are looking for inexpensive yet efficient serum, this is probably your best bet.

LOVE it! The silk therapy smoothes frizzes & flyaways, leaving my hair soft, silky, & shiny. Plus, it smells wonderful! It is a little pricy, but you only need to use a tiny amount at a time, so one bottle lasts really long.

I use this especially during the summer to keep control of my frizz and dry ends. And the amount needed to get the results I love is less then the size of a pea and I have thick, curly and dry hair. I've been using this product for just over 10 years and have yet to find a replacement.

I love this product, When I use it my hair really feels like silk. I can run my fingers through my hair easily even if i've rode on the back of my husbands harley all day!!

great product! does add a little bit of grease, but much less than others. it is definitely worth the price you pay!

Pricey yet effective. Leaves hair glossy and smooth. Scent is good.

I have naturally wavy hair but the wet weather in Washington makes my waves frizzy. If I want to air dry my hair I add BioSilk and it tames the frizz. It's also one of my favorite smells for my hair. My only complaint is it makes my hair greasy if I add too much or put it on dry hair.
