Aveda Smooth Infusion Style-Prep Smoother Leave-In Anti-Frizz Serum, 0.85 fl oz — Silicone-Free, 72-Hour Frizz Control

Aveda Smooth Infusion Style-Prep Smoother is a lightweight, silicone-free leave-in serum that smooths hair, helps repel humidity for up to 72 hours, and protects against heat and UV damage during styling.

This pre-styling serum from Aveda is designed to make damp hair easier to style by evening the hair surface, adding weightless hydration, and guarding against frizz for days. Formulated with mostly naturally derived ingredients, including a sand ginger–derived UV filter and a botanical oil blend, the product aims to enhance shine and manageability without silicones. It’s also vegan and cruelty-free, suitable for those seeking a cleaner beauty option in their styling routine.

How does this serum make styling simpler?

The Smooth Infusion Style-Prep Smoother coats strands to reduce surface roughness so brushes and irons glide more smoothly. Applied to damp hair, it primes hair for blow-drying or heat tools and helps reduce the need for reworking styles.

• Lightweight, leave-in texture that won’t weigh hair down.
• Softens cuticles for easier detangling and quicker blow-drying.
• Compatible with thermal styling up to 450°F when used as directed.

Will it really help with frizz and humidity?

In laboratory testing on frizz-prone hair, this serum demonstrated up to 72 hours of frizz resistance by creating an invisible, water-repellent layer on the hair shaft. That barrier helps keep moisture from causing flyaways and frizz in humid conditions.

• Invisible polymer repels water to reduce humidity-driven frizz.
• Provides lasting smoothing without silicone ingredients.
• Best applied to freshly towel-dried hair and sealed with heat for optimal hold.

What ingredients protect hair from sun and heat?

The formula includes a UV filter sourced from sand ginger that helps shield hair from sun-related drying and fading. A botanical oil blend—Kalahari melon seed oil and Tamanu oil—works to smooth cuticles and add conditioning benefits without heavy buildup.

• Sand ginger–derived UV filter for light sun protection.
• Kalahari melon seed oil and Tamanu oil to enhance smoothness and shine.
• Free from silicones, parabens, mineral oil, and synthetic fragrance.

How should I use it for best results?

Dispense a small amount into your palms, emulsify, then distribute through damp hair from mid-lengths to ends before styling. Use sparingly on fine hair and a touch more on thicker textures; follow with blow-drying or other heat styling to lock in smoothness.

• Apply to towel-dried hair; avoid roots to prevent weighing down fine hair.
• Style as usual—blow-dry, curl, or straighten up to 450°F.
• Reapply lightly only if needed; a little goes a long way.

Who is this for? This Aveda serum is suited for anyone seeking a cleaner pre-style product to tame frizz, improve manageability, and add shine—especially people with frizz-prone or textured hair who want silicone-free formulas and mild UV and heat protection. It’s also a fit for consumers who prioritize vegan and cruelty-free beauty brands while keeping styling effortless in humid climates.
