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.

I’m shook 🤯

3 days ago
I fully expected to be very u dwelled by this product because I have naturally wavy hair that is VERY prone to frizz, especially in any amount of humidity. I usually like to wear my hair straight and in the summertime it’s just a losing battle because the second I step outside it’s frizz city and my waves start to show. I have tried SO many products over the years and none of them have ever made much of a difference, so I was not expecting this to work either. Where I live right now is a heat wave with very high humidity levels and my hair is staying smooth, straight, shiny, and sleek and my mind is blown. Truly cannot believe what I’m seeing. I’d give this stuff 10 stars if I could. I also love that it’s really lightweight feeling so I can apply a decent amount of it without it weighing down my hair or feeling like I have too much product in.

Sleek & Shine Anti-Frizz Serum products use argan oil and the Sleek & Shine Anti-Frizz Serum use coconut oil and coca butter. Both should work just as well for dry curly or frizzy hair.
