I've used this product for some time. It is great with keeping the frizzy hair under control.

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).

One of my favorites I actually have this in my hair product basket. I use it every day to style my curly hair. It gives shine and it smells amazing.

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 think I have normal hair, a little more on the dry side. I don't often use conditioner, so after shower, my hair would be really hard to brush out. This solves the problem and makes my hair smells amazing. It is not at all greasy and makes the hair feels light, soft, and smooth. I can definitely tell the difference when I use this. I would recommend this to normal to dry hair.

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.

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 .

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.

It tames frizz and leaves hair feeling soft. When I straighten my hair I put this in as I finish it, which helps alleviate the greasy feeling some people complain of and also helps to de-pouf my thick hair. As much as I'd like to be rid of silicone, I haven't found another product that gives me the same results and is silicone free.

I am a former stylist and I love BioSilks therapy hair treatment. A little goes a long way. Does a great job taming flyaways and smells great! I'm always on the hunt for the next new best thing but I have yet to come across something I like as well as this product.

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.

This stuff works wonders for your hair. Its not very expensive and makes my hair smell and feel amazing.

love it

Love Biosilk! It smells good and makes my hair shiny and smooth. Other shine serums leave my hair feeling greasy, but this doesn't!
