[This review was collected as part of a promotion.] I think that this product is amazing. I have used defrizz and shine serums before and they leave my hair greasy. This stuff..... leaves my hair feel smooth and flowing. No build up and no greasy feeling. I love it and have told all my friends and coworkers about it.

[This review was collected as part of a promotion.] I was extremely excited to try this out as I have very thick and frizzy hair. Since I have such thick wavy hair, I had to use several pumps of the serum. I found that if I used more than 4 pumps, my hair would get oily very quickly (which is saying a lot since it normally doesn't get oily until about day 5 of not washing it). If I only use 3-4 pumps, my hair doesn't get oily, but the serum doesn't help much with the frizziness. In the picture attached, the left side is when my hair was still wet and I applied the serum. The one on the right is a few hours later when my hair was dry. As you can see, there's still a lot of frizz. Overall, I'm not a huge fan of the product as it doesn't take away the frizz.

[This review was collected as part of a promotion.] I have really difficult hair. It's thick, curly, and frizzy, and I struggle with baby hairs that make me look like a lion. I have tried every anti-frizz product under the sun and nothing has worked for me. I'm a stay-at-home mom with two kids under two years old, so I don't have a lot of time to fix my hair. Usually, I put it in a bun (because ponytails are too frizzy) and go about my day. Garnier Fructis Sleek & Shine Anti-Frizz Serum has been a miracle worker for my hair. This is the first time in my life that I have been able to wear my hair down with straightening or curling it. It has tamed the frizz like no other. I don't have baby hairs sticking up all over the place anymore, and I can finally not have to wear my hair up everyday. My only complaint is my hair does get oily faster (about two days between washes instead of 3-4), but for me, that is a small price to pay for not having a headache from having my hair up all the time! I am DEFINITELY going to continue using this product.

I have naturally curly hair and live in a state that gets extremely hot and humid so frizz is an everyday struggle for me. This product is something I use everyday and will continue to use! It helps keep all the fly always down and my curls looking tight! Absolutely love this product.

[This review was collected as part of a promotion.] The pros of this is that it has an amazing smell that definitely lasts and a little definitely goes a long way. I believe this product gives more hydration to hair than it actually does taming any frizz. It helps, but if you have a lot of frizz then this may lessen it just a bit, but won't tame the problem completely unless yoy want to risk having your hair look too oily by using more than your hair can absorb. I can say the more you put it into your daily showsr routine, the more it works. I would recommend this product for those that are looking for that extra hydration and to tame the stragglers, but if you have a real frizz problem, you may want to add something to help with control.

[This review was collected as part of a promotion.] I've tried this product several times on my damp hair and it has yet to do anything for me. I'm still frizz city over here. It smells nice though. It may work better on dry hair. I plan on trying it out when I pincurl my hair.

[This review was collected as part of a promotion.] While putting it on I was a little worry it was too runny to do the job,I was wrong in the whole concept it work like a charm I was not worried at all in the whole day about my hair .And lets talk about the smell my husband could smelled all the way in the back I loved it.

[This review was collected as part of a promotion.] As someone with fine/medium wavy hair (and a lot of it), I have used and loved Garnier's hair products for a long time - namely their conditioners and leave-in conditioner, which I find to be the best drugstore product available for wavy hair. Frizz serums have rarely worked for my hair whether I air-dry or blow-dry it (they either have no effect or are too heavy and leave my roots oily). This serum was not overly oily, which I appreciated, but it did not seem to have much effect on my roots, where the frizz tends to concentrate. Overall, it smelled amazing and helped slightly with frizz control but not enough to repurchase. If leave-in conditioner is not an option for someone with very fine hair, this serum may be a good alternative. I have found better results with Garnier conditioning products and would continue to use those instead.

[This review was collected as part of a promotion.] I typically avoid using non-salon brands due to fear of low quality ingredients. However, I’m shocked at the results; my hair looks great. I first tried out the product and noticed a great smell. Although the serum is thin, it does it’s job without flattening out hair or making it look too greasy. I can go two to three days without washing my hair with the scent still being present.

Gave a good shine but my hair felt a little weighed down. Smelled amazing loved the smell. I'm just trying to find something light weight and that will help define curls and not weigh them down. I think this would work better on if you were taking a straighter hair approach.
