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

Aveda Smooth Infusion Style-Prep Smoother is a lightweight leave-in serum that instantly smooths hair, primes strands for styling, and helps resist frizz and humidity for up to 72 hours.

Lightweight and silicone-free, this pre-styling primer from Aveda smooths the hair surface, adds weightless hydration, and helps protect polished styles from moisture and sun-related dryness. Formulated with 98% naturally derived ingredients, including a sand ginger–derived UV filter and a botanical oil blend, it’s designed to make styling easier while preserving shine and manageability. The formula also features Aveda’s Pure-Fume aroma, combining Australian sandalwood, bergamot, and palmarosa for a subtle botanical scent.

How does this serum make styling faster and simpler?

The Style-Prep Smoother works as a primer: it smooths cuticles and reduces surface friction so brushes and heated tools glide more easily. That means quicker blowouts, fewer snags, and a sleeker finish with less effort.

• Instantly smooths hair surface for easier comb-through and styling
• Lightweight texture that won’t weigh hair down or leave residue
• Applies to damp hair to improve tool performance and style longevity

Will it help control frizz and humidity?

This serum creates an invisible, silicone-free shield that repels water and helps defend against frizz for up to 72 hours in laboratory testing on frizz-prone tresses. It’s designed to maintain a smoother appearance even in humid conditions without relying on heavy silicones.

• Invisible polymer helps repel moisture and reduce puffiness
• Suitable for repeated styling days when humidity is a concern
• Non-greasy hold so hair stays touchable and mobile

Does it protect hair from heat and sun damage?

Yes — the formula contains a UV filter derived from sand ginger to help protect the hair’s surface from sun-related drying and from heat styling up to 450°F. This provides extra security when using hot tools and when spending time outdoors.

• UV filter helps guard against sun-induced dryness
• Heat protectant support up to 450°F for safer blow-drying and thermal styling
• Pairs well with additional heat-protection products if you need extended thermal defense

How do I use the Aveda Style-Prep Smoother in my routine?

Work a small amount of the serum between your palms and distribute it through damp hair, concentrating on mid-lengths and ends. Proceed to blow-dry or style as usual; a little goes a long way, so start light and add more where needed.

• Apply to towel-dried hair before blow-drying or air-drying
• Use sparingly on fine hair to avoid over-conditioning
• Reapply a small touch to dry ends for targeted smoothing between washes

Who is this for: Aveda Smooth Infusion Style-Prep Smoother is ideal for anyone seeking a lightweight, silicone-free primer that improves manageability, reduces frizz, and supports heat styling. It’s well suited to frizz-prone or chemically treated hair, those who style daily and want added humidity resistance, and shoppers who prefer products made largely from naturally derived ingredients and a botanical scent profile.
