Garnier Fructis Sleek & Shine Anti-Frizz Hair Serum for

Garnier Fructis Sleek & Shine Anti-Frizz Serum is a lightweight, leave-in argan oil–infused treatment that smooths flyaways, boosts shine, and helps control frizz for up to 72 hours when used with the Sleek & Shine system.

Engineered for hair that resists humidity and styling, this leave-in serum combines Argan Oil with Garnier's Vegan Kera System to soften, reinforce, and smooth strands without weighing hair down. It works as both a finishing serum and a nourishing lightweight oil, suitable for damp or dry hair and designed to be part of an everyday routine or a travel-ready touch-up.

How does this serum reduce frizz and fight humidity?

The formula seals the hair cuticle and adds moisture with argan oil while Vegan Kera helps strengthen weak spots along the strand. Together they create a barrier that limits moisture intrusion from humid air and smooths surface texture for a sleeker appearance.

• Argan Oil: nourishes and increases surface gloss.
• Vegan Kera System: reinforces strands for reduced breakage and smoother feel.
• Humidity-resistant finish: helps maintain sleekness in high-moisture conditions.

Can I use this on all hair types and how much should I apply?

The serum is formulated to suit fine through thick hair without leaving a greasy residue. Start with one pump for fine hair, two pumps for medium hair, and three to four pumps for long or thick hair, then adjust based on texture and style goals.

• Fine hair: 1 pump to avoid weighing strands down.
• Medium hair: 2 pumps for balanced smoothing and shine.
• Thick/long hair: 3–4 pumps for full mid-length to end coverage.

When and how should I apply the serum for best results?

Use the serum on damp hair after showering to lock in moisture and create a smooth base before styling, or apply to dry hair to tame flyaways and add finishing shine. Rub the product between palms and distribute through mid-lengths to ends; do not rinse.

• Damp application: primes hair for blow-drying or air-dry routines.
• Dry application: smooths flyaways and adds final polish.
• Pump activation: twist nozzle 90° to unlock and pump 5–10 times to prime if needed.
