[This review was collected as part of a promotion.] I received this as a Buzz campaign to try. I first noticed that it smelled nice. Once trying I will say that my hair did seem smoother and less frizzy. I live in a humid area and was able to tell the difference. It didn't leave any residual feeling on my hair either. Also, it doesn't take much product!

[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.

[This review was collected as part of a promotion.] This product actually worked. Not sure if it should always be with the combination of the same shampoo, conditioner and serum from this line but I washed my hair and blew it out and it looks very sleek compared to other times and frizz is definitely controlled. Smells great, but a little goes a long way! I don't care for the packaging, wish it was a squeeze bottle.

[This review was collected as part of a promotion.] I will say this product could weigh the hair down if you use too much so watch out. You only need a pea size amount of this for it to work. Pea sized amount on wet hair is how I use it on my hair and my daughters and it leaves our hair frizz free till we wash it again. So amazing product.

[This review was collected as part of a promotion.] This anti-frizz serum is absolutely amazing! Once I got it I knew I just had to smell it. It smells wonderful! After use my hair was completely soft and frizz free! I will be continuing my use of this product for many many more! I am going to tell people about this because I highly recommend this product. I couldn't believe how well it worked for me. Over all I am super happy with this serum and firmly believe you will be too! Everyone who needs anti-frizz in their life needs to try this out!

[This review was collected as part of a promotion.] Finding the right anti-frizz product for my hair has been a journey I've been on for 10 years. What I can say completely honestly about Garnier Fructis Sleek & Shine Anti-Frizz Serum is that it truly does work to massively decrease the amount of frizz in my hair. I am fairly faithful to the anti-frizz product I currently use, but the Garnier product did exactly what it promised to, and not many can with my thick, unruly hair. The negative of this product, for me, was that I have extremely curly hair, and while it fights the frizz it also left my hair with no body and it looked weird, somewhere between curly and wavy and a complete mess. So while this product is absolutely not made for people with curly hair, it does do exactly what it was meant to. A success for the product, a semi-success for me personally.

[This review was collected as part of a promotion.] While it does tame my wild hair, it does make my hair greasier, much quicker. I've tried using a very small amount, but it still makes it look and feel greasy. I think I'll only be using it when my hair is extra frizzy and needs something to calm it down.

[This review was collected as part of a promotion.] Okay, so basically this product is supposed to help with frizz. Frizz is my best friend! I was excited to try a new product to combat frizz. When I tried the Garnier Fructis Sleek & Shine Anti-Frizz Serum, I was AMAZED at how less frizzy my hair looked. It had a tropical like scent and also gave my hair this beautiful shine but did not leave it greasy. It also somehow acted as a detangler. All together, I loved it. However, it did not eliminate all my frizz, sadly, and I still had a few fly aways when I put my hair into pig tails. All-in-all, it was a great product.

[This review was collected as part of a promotion.] I used this product alone and mixed with my beloved leave-in conditioner. Alone? This product takes my fried, bleached fly-aways back to the hanger. They are soft and manageable. No tangles! In addition to my leave-in conditioner? AMAZING. I have hair that you never would have thought went through three rounds of 40 volume bleaching nightmares. This will definitely stay in my routine!

[This review was collected as part of a promotion.] I think this product is really nice for many different hair types. My sister has used this line from Garnier and it's done wonders to control her frizzy, curly hair. This product was really great on my hair too even though mine is straight and short. It made my hair feel softer and overall just looked healthier. I didn't even think my hair felt dry until using this product and seeing the difference. First time using it, I was really worried it was going to make hair look and feel greasy. A little does seem to go a long way, as half a pump seemed plenty for me. It quickly absorbed into my hair instead of just laying on top of it. This isn't a product I personally would use everyday for my hair type, but would use occasionally to restore hydration and shine.
