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

Smell change was a horrible and nausiating idea.

10 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.

So I have long thin hair that tangles easily after the shower every time. I tried buying so many different products and some have been hundreds of dollars to see finally work. I have tried buying detangler and brushes that also help de tangle but I bought this sleek and shine anti frizz serum and within minutes it transformed my very tangled mess that used to take me 20 minutes or more to de tangle to 10 minutes or less to have de tangled. It smells amazing and didn't leave my hair feeling heavy or oily. It was also in a totally reasonable price point. I was pleasantly surprised and will keep using this product. I am excited to buy their shampoo and conditioner. I also have the leave in conditioner and that also helps. I also feel like I generally now have less frizz. My hair is shiny and soft. This took a 20 minute de-tangle routine down to less than ten minutes! 34 yr old.

Yes, I recommend this product.

SOOOO GLAD I FOUND YOU!!!!

I bought the shampoo at my local supermarket because I was already there food shopping. My husband reminded me he needed shampoo so I looked for one that hydrates dry hair. My hubby has dry curly silver gray hair with slight frizz on the ends which puffs out of control over the hrs. Of the day. First time use of this product and I noticed his hair was staying in place ALL day EVERYDAY! I am so impressed I went back to the store and bought the conditioner and leave in serum. We couldn't be happier to find products that actually work, that effectively fights FRIZZ. I also started using the serum to control my frizz cause here comes the summer humidity!!! I highly recommend this these products.

Yes, I recommend this product.
