In my experience, if I ever repurchase a product I’ve already tried, it’s for two reasons: It’s actually effective and payable. If not, there is no way I will continue to use it and make it a part of my daily routine. I estimate over 14,000 Amazon buyers agree with me; Garnier Fructis Sleek and Shine Anti-Frizz Serum is on her repeat buy list. Best of all, it’s currently on sale ahead of Prime Day.

Formulated without parabens or silicone, this serum is safe and effective for all hair types including curly, wavy, thick and fine hair. Credit goes to its key ingredient, responsibly sourced argan oil from Morocco. As soon as you apply this serum to damaged strands, the argan oil coats and penetrates each hair follicle to create instant smoothness and shine without weighing down the hair or leaving a greasy residue. It is perfect for you and your roommates to keep in the bathroom and use together.

Similar to a leave-in conditioner, the serum is so effective and powerful that it can even be used in 97% humidity to tame unruly frizz. You’ll never have to plan hairstyles around the weather again. Just one pump of this serum is enough to straighten all hair, whether you apply it to damp or dry strands.

Garnier Fructis Sleek and Shine Anti-Frizz Serum

Reviewers note that it has a mild tropical scent that doesn’t linger, making it perfect for anyone. One buyer even bought this serum as a dupe for the Paul Mitchell Super Skinny Serum. “This has the same main ingredient as [the] Super skinny serum but I can honestly say I like it better,” they wrote. “It makes my hair shinier and less frizzy.”

Another reviewer said that this serum takes her from “looking like Medusa to a tamed, sophisticated ponytail” in minutes with very little effort. If you’re a curly haired girl who is skeptical, consider a review from another shopper who said, “I have very curly but frizzy hair and this oil takes away the frizz, no heat required. It’s not greasy and I like the smell. I’ve been using it for years. I like it better than Biosilk.”

Keep this serum handy to ensure your strands stay in place no matter what Mother Nature is doing outside. Unbeatable on Amazon for €5.
