Can't say enough about it

12 years ago
I am a mom to a beautiful little girl who lost her hair during medical treatment - when it regrew, it was very fine, but she has a lot, and it is quite wavy. You can imagine what brushing it was like. Sheer torture. I figured it wouldn't hurt to try a bit of my Sleek & Shine in her hair, and I can NOT get over the difference! We used to have to braid her hair before bed to have any chance of getting a brush through it in the morning, now she goes to bed with her hair down, and I can finger comb it in the morning - no snags, no frizz and a BEAUTIFUL shine. For a little girl who has had to go through losing her hair, now getting constantly complimented on her beautiful locks puts her on cloud 9 every time. Thanks, Garnier <3

Most Helpful Critical Review

Smell change was a horrible and nausiating idea.

11 years ago
I have loved this product from day one it hit the shelves. I used it religiously after each hair washing as I have extremely long, baby fine hair that is extremely prone to tangles and mats. I have always been completely in love with this product until my most recent purchase. I buy a new bottle about six times a year. I got the most horrible shock when I opened and used the latest bottle for the first time. The smell had completely changed (for the worse). It has only what I can describe as a melon based smell now. I have a complete aversion to any smell in the melon family as is makes me uncontrollably nauseous. I have to officially say I can no longer use the product I have swore by for so many years that I can't remember the last time I had less than two bottles in my cabinet at the same time. I have now began a search for a new serum from a different company because of this. I love all of the Fructis lines of products and never had an issue until now (well besides they stopped carrying the shampoo and conditioner line I used about 8 months ago in the stores in my area but I found a suitable replacement within the Fructis lines which also works perfect for my hair). I have always recommended Fructis anti-frizz serum to my friends. It is unfortunate that I can no longer use my most trusted and loved hair product of all time. It took me years to find it and now I have to move on. If you can not handle the pungent aroma of melons, I suggest you look elsewhere for a serum like now I am in the process of with a sadden and heavy heart. I must now move away from the Fructis line for my hair serum.

Affordable product.

a day ago
The Garnier Fructis Sleek & Shine Anti-Frizz Serum helps smooth my hair and control frizz, without feeling stiff or crunchy when I'm blowing drying it. A small amount goes a long way, and it doesn't leave my hair feeling greasy or weighed down when I use it on damp or dry hair. I also love the fresh scent, and the pump bottle makes it easy to dispense just the right amount. For the price, it's a great value, and I'd definitely recommend it to anyone looking for an affordable serum that delivers soft, smooth, and manageable hair.

The best hair serum I’ve used in a long time

3 days ago
I’m OBSESSED with the Garnier Fructis sleek & shine anti-frizz serum! It smells AMAZING and always leaves my hair feeling smooth, shiny, healthy and without frizz. It lasts for hours, even when I’m out in the heat chasing around kids all day. I never leave the house without apply some (and sometimes, I even do it before bed too just as an extra treat for my hair!).

Actually makes a difference !

I love this serum !! It does exactly what I need it to do. My hair is naturally curly, and so straightening it, and keeping it straight in the humidity is extremely hard for me. Using this makes a difference every time! It smells so good it’s not over powering either . Keeps your hair shiny and moisturized . I recommend for people who struggle with frizz !
