[This review was collected as part of a promotion.] I've tried using about a pump on both dry and wet hair. When I used it on dry hair (straightened), I found that it made my hair way too greasy. However, when I tried it on my wet hair and left my hair curly, I didn't have that problem. I didn't notice too much in the frizz control department. I think this product would be great to bring to the beach and use in my hair when I get out of the water or if I'm going to by in the sun a lot. I feel like it would do a good job of taming the frizz if my hair was more dry and damaged like in the summer. I didn't notice anything out of the ordinary on the smell. It had about the same level of fragrance as most hair products do. Overall, I am definitely planning on giving this product another try on my next beach vacation and I can see it being more helpful for everyday use if your hair is on the very dry/damaged side.

[This review was collected as part of a promotion.] This product is wonderful. I just used it for the first time and can already notice a difference. Once I got out of the shower I applied this product to my hair and then blow dried my hair. Usually after drying my hair is going crazy, frizzy and puffy. This product help a ton!

This product used to be 5 star. I’ve used it every single day for a decade and it’s been my one and only constant in my hair care journey. BUT you ruined it!!! It honestly makes me very upset. Why oh why oh why did you add keratin/protein?!? This product was absolutely perfect the way it was. My hair is protein sensitive and If I had to guess? A lot more people are going to discover that they are also protein sensitive bc every product out there now is loaded with the stuff. It’s just not necessary for this serum. Please please please make it without it!!! This is my hands down single favorite hair care product ever and I’ve been questioning using it every time now because it’s just not the same and protein really changes my hair texture to straw. Whereas before this had the protein it absorbed instantly into my low porosity hair whereas other oils and serums just sit on top. I can’t use coconut oil either because it won’t absorb. But my hair will just drink this product up and is so shiny and soft and smells so good. But you had to go and ruin it

I've repurchased this multiple times and will probably keep buying it. It's drugstore so it's affordable, and one bottle lasts me at least a year because I only use it after washing my hair (2-3x/week). I pump some out, rub it between my hands, and then through my hair avoiding my roots. It smells so good and has been a staple for years. It really does make my hair smooth and shiny and keeps my hair frizz-free.

[This review was collected as part of a promotion.] I am in love with this!! It leaves my hair frizz free and smells amazing! Doesn't leave my hair feeling greasy feeling like some others I have tried. Great for when I wear my hair straight or curly!

[This review was collected as part of a promotion.] I am really amazed by this product. I don’t blow dry my hair so I was worried that it would just make my hair oily and to my surprise it did NOT! Now I have dry hair and could never get it as soft as it is now because of this serum. It made my hair feel soft from the moment I applied it to my hair. I used it for a week straight to see if it was just the first day and it works day after day! And I have long hair and one pump gets all my hair. It does last. I hands down love it!

[This review was collected as part of a promotion.] I have very fine ringlet curls and am always looking for a new product to use on them. I used to use a mousse but it made my hair crunchy so I have switched to a cream. Using the cream I found my hair was a little frizzy still so hearing that this serum was for anti-frizz I was really excited. I used this product like the instructions said and I did find it helped with frizz, but I found it made my hair get greasy faster. I think I may have used too much. It smelled really good and wasn't sticky or too thick. I would recommend using it in conjunction with other products you normally use. I will keep using it but probably wouldn't buy another bottle. For people with straight hair or thicker hair it would probably be good.

[This review was collected as part of a promotion.] My hair isn't exactly the healthiest. I used the garnier fructis sleek & shine on a RAINY day-frizz alert? Not this time! I had so many compliments on my hair. My hair stayed soft with no frizz all day long!

[This review was collected as part of a promotion.] I was really apprehensive to try this product because my hair tends to get really oily. Due to having thin hair, I only wash my hair every other day or else it gets brittle and dry. My routine for the Sleek & Shine Anti-Frizz Serum was to use one pump after taking a shower. I would concentrate on the ends and then run my fingers through the top/closer to my scalp. I tend to have fly aways because my hair breaks and the little hairs stick up. The smell is really light and fresh. The consistency isn't too thick that it's hard to spread throughout, but not so watery that it gets everywhere. I really like how it feels. I noticed that once my hair dries, it is shiny and more manageable. The shininess isn't the oily, artificial oiliness that some leave-in products leave behind. IT's just enough that your hair looks healthy and thicker, too! Overall, I'd recommend it to my friends. It hits all the requirements for a leave-in product for me. It smells good, doesn't leave my hair oiler, right consistency/feel, and does what it intends to do!

[This review was collected as part of a promotion.] After using the Garnier Fructis Sleek & Shine Anti-Frizz Serum for about a week now, I think it is just okay. I have tried it on both damp and dry hair and found that if I apply it on my hair while damp, it weighs down my hair without providing much anti-frizz relief. The best way I've found to use it is to wait until my hair is dry and apply to my ends and work up to mid-shaft. Even on dry hair, it did not quite provide me with the anti-frizz I was hoping for, however, the product does help make my hair shinier which is a plus. Another great fact about this product is that even when I accidentally applied too much product, it did NOT look greasy after brushing out my hair! Which is a major upgrade compared to other products. Overall, good for shine, does not look greasy, but no help in the frizz department.
