This stuff works miracles. I have waist-length, stick straight, thin, natural blonde hair. I don't use heat on it and i take GNC's hair skin&nails vitamin so it is pretty healthy. It stays shiny and smooth all summer, and doesn't get frizzy in humidity. BUT during the winter, my hair is a nightmare. It dries out horribly and the ends look scraggly like they've been tied in a braid, and the roots are impossible to brush. My front pieces stick straight out and any type of friction causes insane static. I shock myself every time I touch a light switch. However, if I put this stuff on at night after showering(ENDS ONLY!) and comb it through with my fingers, and let it airdry overnight, when I wake up it looks as smooth, shiny, and healthy as it does during the summer.

[This review was collected as part of a promotion.] I personally loved the Garnier fructis sleek and shine anti frizz serum! It made my hair feel so soft and it was really shiny! I love that it did not make my hair greasy or even appearing that way! Overall i would recommend this frizz serum to anyone with some crazy looking hair on humid days if you want to just feel and look beauitful without the frizz! It worked wonders on my hair!

[This review was collected as part of a promotion.] I seriously loved the garnier sleek and shine anti frizz serum! It made my hair completely smooth and was so easy to use! When I got the serum I was so anxious and excited to use it because my hair was such a mess. Completely frizzy. And I will say after even the first use it was already working! And I will definitely be using this product in the future!! One thing I wanted to know before using it was if it would work with sensitive skin and such and it totally does! I am so excited about this product and Garnier is awesome!

[This review was collected as part of a promotion.] I really enjoyed using this product. The first thing I noticed was he smell. Oh my gosh it smells amazing! The serum was very light. Not heavy at all. It had a very smooth and silky feeling. I have very course hair, that I usually wear in an Afro. Because my hair is so think and tightly coiled hair, I didn’t do much to to tame that. However, when I wore a bun or a ponytail, it did a pretty nice job. It wasn’t perfect, but it was pretty close. My mother has also used this product and she enjoyed it as well. I will definitely be using this product again.

[This review was collected as part of a promotion.] This serum smells amazing. I do not put too much because I have fine hair and I am afraid it will weigh my hair down. A little serum goes a long way. It has definitely helped me control my frizzy hair.

[This review was collected as part of a promotion.] I have mixed feelings about this. First of all it smells amazing. It feels great putting it through my hair and it doesn't look greasy. On the other hand, it felt like it made my hair more dry. I didnt like the way my hair felt later on in the day. It still looked nice tho.

[This review was collected as part of a promotion.] I tried this today as well as put some in my husband's hair. We both have pretty frizzy hair, and it calmed my husband's enough where my mother asked if he got a haircut! I definitely love this product and will continue using it.

I love this product so much!!!!!!!!!!!! It is a bit pricy but it will last you for a few years for sure. This product is very effective and I use it whenever my hair is frizzy. You really don't need a lot. I will totally buy this product again and I was recommended this product by one of my friends. I am very satisfied with my purchase.

[This review was collected as part of a promotion.] This is a great hair serum. I have frizzy wavy hair and need something that will calm it down while not weighing it down. It is lightweight and smells great. I have thick hair and I use a small amount after my shower and it really keeps my hair looking great.

[This review was collected as part of a promotion.] As I said in my reviews for the Garnier sleek and shine shampoo and conditioner, I usually avoid silicones. After using this product line I can really see their benefits. The occlusive power of the silicones helps keep moisture in and frizz out. This serum provided great wave definition and was light enough to not weigh my hair down.
