Garnier Fructis Sleek & Shine Hair Serum for Frizzy Dry Hair, 1.7 fl oz — Heat Protects to 450°F, Lightweight Shine

Designed for frizzy, dry hair, this lightweight serum works as part of the Fructis Sleek & Shine system to lock in sleekness for multiple washes. Enriched with alpha-silane, the formula is engineered to deliver long-lasting smoothness while remaining non-greasy and free from parabens, phthalates and DMDM hydantoin. Cruelty-free certified, it’s intended to be applied to damp hair before blow-drying and thermo-locked with a flat iron for best results.

How does this serum reduce frizz and keep hair smooth?

The serum uses alpha-silane to create a lightweight coating that helps align hair strands and repel humidity-driven frizz. When heat is applied during styling, the thermo-active ingredients form a sleeker surface that reflects light for a glossy finish.

• Alpha-silane technology helps bind and smooth hair fibers.
• Heat activation locks the sleek effect into the hair cuticle.
• Water-resistant finish helps maintain smoothness between washes.

Will it protect my hair from heat tools like blow dryers and flat irons?

Yes — the formula provides heat protection up to 450°F when used as directed, helping reduce direct heat stress during styling. Apply to damp hair before blow-drying and follow with a flat iron to seal in the protective benefits.

• Apply evenly to damp hair after shampoo and conditioner.
• Blow-dry fully, then flat-iron to thermo-lock the serum.
• Non-greasy texture prevents weigh-down while offering protection.

How should I use this product for best, long-lasting results?

Shake the bottle well, dispense one pump at a time onto damp, towel-dried hair and distribute from mid-lengths to ends; do not rinse. For a longer-lasting sleek look, use the full Sleek & Shine system (shampoo, conditioner, serum) and finish with heat styling to seal the formula.

• Use after Sleek & Shine shampoo and conditioner for optimal effect.
• Start with 1 pump; add sparingly for thicker or longer hair.
• Finish with flat ironing to thermo-lock results up to five washes.

Is the formula gentle and ethically made?

The serum is formulated without parabens, phthalates and DMDM hydantoin, offering a simpler ingredient profile for everyday styling. Garnier Fructis products, including this serum, carry Cruelty Free International Leaping Bunny approval.

• Free from parabens, phthalates and DMDM hydantoin.
• Leaping Bunny cruelty-free certified.
• Lightweight, non-greasy and suitable for heat styling routines.
