[This review was collected as part of a promotion.] I have frizzy curly, thick, wavy hair. This stuff does wonders for me! I've used this in the past and it's my favorite thing. I used before I straighten my hair, or when it rains, or when use mousse in my hair. I love this product so much!

[This review was collected as part of a promotion.] I have big frizzy hair and most things don’t work for me but this serum from Garnier made my hair soft and all the frizz was gone! I definitely recommend this for anyone dealing with frizzy hair they think is untameable!

[This review was collected as part of a promotion.] Works wonders on my hair! I have extremely frizzy, thin, curly hair and any touch of humidity and I'm stuck with extremely poofy untamed hair. Just a drop of this and it seals in shine and makes my hair so much more manageable. Just from experience, I wouldn't use too much because you'll start to get an oily look. I would definitely recommend to anyone with thinner hair or curly, waves hair!

[This review was collected as part of a promotion.] I already love the Garnier Fructis Sleek & Shine Anti-Frizz Serum. I have crazy long hair, and taming it is a hassle. I always brush my hair after it's dry, though it gets really frizzy after. This was a perfect solution. I can add it into my hair when it is wet or dry, and it helps it stay sleek. It also smells so good! I love it year round. I've noticed it seems to keep my hair from looking greasy the next day, or it feels just a bit more voluminous the next day than without it.

[This review was collected as part of a promotion.] This product, unfortunately, did not work well for me. It is tough to find an anti-frizz formula that can combat frizz in the heat and humidity of the Texas gulf coast. This product seemed to work once I applied it to my hair, but before I even walked outside, my hair was already getting frizzy again. The formula was not the easiest to apply. If you aren't careful, your hair will turn out looking greasy.

[This review was collected as part of a promotion.] After only 2 uses, my normally frizzy dry hair is noticeably less frizzy and tamer, which is saying something for how bad it gets in Oregon winters. It also helped defined my waves into a shiny curl, which I love! I love this product and am making it a part of my daily routine! My hair has never looked healthier!

[This review was collected as part of a promotion.] This is so easy to use and makes messy hair easier to comb! I have somewhat wavy nappy hair and ever since I began using this my hair has gotten a lot easier to comb! I highly recommend it plus it gives my hair not only a decent shine but a great smell too!

[This review was collected as part of a promotion.] I love this so much! I live in a very humid city and my hair is always frizzy. I have always hated products like this because I don’t like the crunch that they leave behind BUT this product leaves none of that behind!! It tames your frizz and fly always without leaving your hair all nasty feeling. I love it!

[This review was collected as part of a promotion.] It leaves my hair clean, silky smooth, but not flat. It has vitamin E and argan oil, which helps nourish the hair and prevent frizzies. It's also paraben-free and vegan. The only negative is that it isn't sulfate-free, although some of their conditioners are.

[This review was collected as part of a promotion.] * I received this product for free in exchange for my honest review.* The Garnier Fructis Sleek & Shine Frizz Tamer works great! I struggle daily with baby hairs sticking out all over the top of my head. Once I use this product, I had no more. It's smoothed them out and laid them down flat without leaving any residue at all. My hair did not feel any different and I couldn't even tell that I put anything in my hair. What an amazing idea! I highly recommend this product to anyone trying to fix baby hairs, flyaways, and frizz.
