Garnier Fructis Sleek & Shine Anti-Frizz Hair Serum, 5.1 fl oz 2-Pack — Argan Oil, up to 72HR Frizz Control

This leave-in serum combines argan oil with Garnier’s Vegan Kera System to penetrate strands, help reduce surface roughness and create a humidity-resistant finish. Designed to be used on damp or dry hair, it works as a finishing oil and everyday frizz controller without weighing hair down or leaving a greasy residue. The bottle is partly recycled and the formula is Cruelty Free International Leaping Bunny certified.

How does this serum help on humid days?

The formula builds a light barrier on the hair surface that resists moisture from the air, helping hair stay smoother for longer. When paired with the Sleek & Shine shampoo and conditioner, Garnier reports up to 72 hours of frizz control in high humidity conditions.

• Argan oil helps soften and add slip to strands for easier styling.
• Vegan Kera System reinforces hair for improved manageability.
• Use with matching shampoo and conditioner for maximum humidity protection.
• Works as a lightweight finishing oil to maintain a polished look.

Can I use it on wet and dry hair—and how much should I apply?

This serum is formulated for both damp and dry hair, so you can apply it after towel-drying or to tame flyaways anytime during the day. Start with a small amount and increase based on hair thickness and length to avoid buildup.

• Fine hair: 1 pump, rubbed in palms and smoothed through mid-lengths to ends.
• Medium hair: 2 pumps for fuller coverage and control.
• Thick/long hair: 3–4 pumps, distributed evenly to prevent heavy spots.
• No rinse required—use as a finishing step or touch-up product.

Will this product weigh my hair down or leave residue?

The serum is designed to be non-greasy and lightweight, serving as an oil alternative that delivers shine without obvious buildup when used as directed. Proper dosing and even distribution are key to maintaining a natural, touchable finish.

• Lightweight texture spreads easily for an even, non-oily look.
• Use minimal product on roots; focus on mid-lengths and ends.
• Regular use with compatible cleansing products helps prevent residue.
• Suitable for a variety of hair types from fine to thick.

How do I start the pump and prime the bottle?

The pump ships locked for safety and must be activated before first use. After twisting the nozzle to unlock, you may need to prime the mechanism by pumping several times until the serum dispenses smoothly.

• Twist the nozzle 90 degrees until it clicks to unlock.
• If nothing dispenses, pump 5–10 times to prime the airless system.
• Store upright and keep the cap on to protect the nozzle between uses.

Who this is for: Garnier Fructis Sleek & Shine Anti-Frizz Serum is aimed at people who want a convenient, everyday frizz solution—those with naturally frizzy, humidity-prone, dry or textured hair who prefer a lightweight leave-in treatment. It’s also a good option for anyone seeking an at-home alternative to salon glossing or frequent blowout touch-ups. If you want manageable, shinier hair without heavy oils or build-up and prefer cruelty-free formulations with greener packaging elements, this serum fits naturally into your routine.

Note: Avoid contact with eyes; for external hair use only. For best results, combine with Garnier Fructis Sleek & Shine shampoo and conditioner as part of a complete routine.
