Instructions of Use
Close subpanel
Step 1: Wash and condition your hair
For best results, use Garnier Sleek & Shine Shampoo and Conditioner.
Step 2: Dispense the serum
Pump a small amount into your palm (adjust the amount based on your hair type and length). Use 1 pump for fine/short hair, 2 for medium, and 3–4 for thick/long hair.
Step 3: Rub your hands together
Spread the serum evenly between your palms.
Step 4: Apply to hair
Work the serum through damp or dry hair, focusing on the lengths and ends to control frizz and add shine. Avoid roots; focus on mid-lengths to ends. Smooth a pea-size amount onto dry hair as needed to tame flyaways.
Step 5: Do not rinse
Leave the serum in your hair. For a sleek, polished look, blow-dry using a brush.
Note: Vegan Kera System refers to plant-based amino acids (no animal-derived keratin).

Can't say enough about it
BeeMum

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.

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.

Smells nice and wonderful texture! The only thing is, I feel like when I put it in my hair after my leave in conditioner it actually caused a little bit of frizz that I didn’t have before and it’s supposed to be antifreeze, but it’s still not awful by any means

Product works great and quickly. Easy pump packaging making it easy to apply. Instant shine and smooths split ends. The scent is a bit strong it doesn’t smell bad but it is powerful. Some residue after applying so wash your hands!

This anti frizz serum makes your hair so silky and shiny and truly keeps you frizz free. Apply it to damp hair to avoid getting overly greasy or a small amount gently to the ends if your hair is already dry. Love to use a little of this before curling my hair or right after a shower and let it air dry

I’ve been using this serum after styling, and it helps smooth my hair without making it feel greasy. It adds a nice shine, helps reduce frizz, and has a peasant scent. A little goes a long way, and the pump makes it easy to use. Overall, it’s great everyday hair serum.

I have used this oil before and really liked it helped a lot with my frizzy hair and it didn’t make my hair look oily. And it absorbed pretty quickly into my hair.

A: Hello Veera! Both the Sleek & Shine Anti-Frizz Serum and the Sleek & Shine Anti-Frizz Serum are great for smoothing frizz control both leave the hair shiny, healthy and smooth. 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.
