Aveda Smooth Infusion Style-Prep Smoother Leave-In Anti-Frizz Serum, 3.4 fl oz — 72H Frizz Defense & Heat Protectant

This pre-style treatment from Aveda is formulated to instantly refine hair’s surface, making blowouts and everyday styling faster and more manageable. The silicone-free primer uses a blend of naturally derived ingredients—98% per ISO 16128—to hydrate without weighing hair down, while an invisible polymer helps repel humidity. It also includes a sand ginger–derived UV filter to guard shine against sun and heat exposure up to 450°F. The scent is a Pure-Fume blend of Australian sandalwood, bergamot and palmarosa, crafted from flower and plant essences.

How does this serum make styling easier?

Applied to damp hair before styling, the serum instantly smooths the cuticle and creates a uniform surface so brushes and irons glide more smoothly. That means less time spent battling flyaways and fewer passes with heated tools. The lightweight formula avoids buildup while giving consistent slip for easier shaping.

• Use a small amount distributed through damp hair to prep for blow-drying or heat styling
• Creates a smoother cuticle for faster brushing and even heat distribution
• Lightweight botanical oils condition without heaviness or residue

Will it protect hair from humidity and heat?

The product delivers up to 72 hours of laboratory-tested frizz defense by forming an invisible layer that repels moisture and helps maintain smoothness in humid conditions. It also contains a naturally derived UV filter to reduce drying from sun exposure and supports heat styling up to 450°F when used as directed. Protection is designed to complement, not replace, heat tools used properly at recommended temperatures.

• Invisible polymer helps shield strands from humidity for extended control
• Sand ginger–derived UV filter helps protect shine from sun and heat
• Suitable as a prep step before styling tools—supports heat up to 450°F

What ingredients are inside and what’s excluded?

Aveda formulates this smoother with a high percentage of naturally derived components, including Kalahari melon seed oil and Tamanu oil to condition and smooth cuticles. The formula is silicone-free and avoids common additives like animal-derived ingredients, parabens, phthalates, mineral oil, and synthetic fragrances. Results come from plant and mineral-based actives and an invisible styling polymer rather than heavy silicones.

• Key actives: Kalahari melon seed oil, Tamanu oil, sand ginger–derived UV filter
• 98% naturally derived per ISO 16128—plant, mineral, and water sources
• Formulated without silicones, synthetic fragrance, parabens, SLS/SLES, and more

How do I use it for best results?

Work a small amount between your palms and apply evenly through damp hair from mid-lengths to ends, then style as usual. For thicker or very frizzy hair, use slightly more product but avoid the roots to prevent weighing hair down. Reapply only to dry ends sparingly if needed for touch-ups; do not oversaturate.

• Apply to towel-dried hair before blow-drying or heat styling
• Start with a pea-to-nickel sized amount and adjust based on hair thickness
• Focus on mid-lengths and ends; avoid applying directly to scalp
