Garnier Fructis Sleek & Shine 10-in-1 Leave-In Spray - Smoothes

Our review of Garnier Fructis Sleek & Shine finds it best for people with frizzy, dry, or color-treated hair who want a quick, one-step leave-in that tames flyaways and adds shine. The single biggest reason to buy is its multitasking formula that promises 10 benefits in one lightweight spray, including up to 72HR smoothing and heat protection to 450 degree F, which simplifies styling without heavy residue. In testing, it softened hair, reduced frizz on the first use, and left a noticeable shine without weighing hair down for most hair types.

Key Features

• 10 Benefits in 1: Combines multiple actions-smoothing, strengthening, shine, frizz control and heat protection-so you can cut styling steps down to one.
• Plant Keratin & Argan Oil: A hair repair blend with plant-based amino acids and argan oil that helps nourish and visibly reduce damage without greasiness.
• Lightweight Spray: The non-greasy, non-sticky formula leaves hair soft and manageable while avoiding residue or weighdown for most users.
• Heat Protection: Acts as a heat protectant up to 450 degree F, useful for anyone who blow-dries, flat-irons or styles with hot tools.
• Clean Formulation: Formulated without parabens, silicones, phthalates or DMDM Hydantoin and suitable for color-treated hair.

Who It's For

This leave-in works well for people with naturally frizzy, dry or damaged hair who want an easy daily product to smooth and tame flyaways without heavy oils. It is also a good fit for those who use heat tools and need an added layer of protection and shine while keeping routine time low.

Those with extremely oily scalps or who prefer heavy oil treatments may find the finish a little different; a few users reported mixed feelings about oiliness depending on how much product they applied. If you need an intensely moisturizing cream or a silicone-heavy smoothing serum, look elsewhere.
