Key Ingredient
Argan Oil
Used for centuries in skincare and haircare, argan oil is an extremely rich golden liquid with anti-inflammatory and anti-aging effects. Quickly absorbed, this transformative ingredient unleashes nutrients, fatty acids, and vitamin E, soothing and deeply hydrating the skin, and restoring shine to dull hair.
Leave-in anti frizz hair serum for dry, frizzy hair. Part of the Fructis Sleek & Shine system, Garnier Sleek & Shine Anti Frizz Serum blends argan oil with our Vegan Kera System to smooth flyaways, boost shine, and help block humidity.
• Infused with argan oil + Vegan Kera System to nourish, smooth, and reinforce the hair fiber. • Clinically proven: Up to 72 hours (3 days) of frizz control, even in 97% humidity. • Humidity shield: Helps block humidity, smooths flyaways, and leaves a sleek, polished finish. • Scent: Crisp apple, sun-ripened strawberry, and juicy melon; a vibrant, fruity scent.
Formulated without parabens, phthalates, or DMDM hydantoin. The bottle is made of 100% recycled plastic (not including the cap). All Garnier products are officially approved worldwide by Cruelty Free International under the Leaping Bunny Program.

How to Create Your Perfect Frizz-Free Shine Routine
Your sleek shine starts in the shower. Build your smooth foundation with our Sleek & Shine Shampoo & Conditioner- created from gentle, frizz-fighting formulas enriched with Argan Oil to deeply nourish and prep hair for styling.
When:Use this shampoo and conditioner on every wash day to tame frizzy, dry hair. Formulated to cleanse gently while locking in moisture, it provides the perfect base for humidity resistance.
Tips for you:
Focus shampoo on the scalp to remove buildup, then apply conditioner from mid-lengths to ends. Leave on for 2-3 minutes before rinsing with cool water to seal the cuticle and boost shine.
Lock in up to 100 hours of sleekness and intense shine. These lightweight leave-in treatments protect against heat and block out humidity.

Tips for you:
A little goes a long way with the Anti-Frizz Serum—start with one pump, and apply to either damp hair before styling, or to dry hair as a finishing step to seal ends, tame frizz, and protect against humidity. For Diamond Sleek, spray sections evenly before blow-drying or flat-ironing to maximize light reflection and get a Diamond-like hair finish.

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

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 really enjoyed this product. I usually have a hard time with hair oils getting my hair to oily since I do have thick curly hair, but this one actually works pretty well and gives my hair a nice shine and gets rid of some frizz.

I've been really enjoying this serum! It has a lightweight texture and spreads easily through my hair without making it feel heavy or greasy. It helps smooth down frizz and flyaways and leaves my hair looking shinier and more polished. I especially like using a small amount on the ends after styling. A little goes a long way, so the bottle should last quite a while!

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.
