If you, like I, find yourself constantly curious about Reese Witherspoon’s beauty product arsenal, huddle up — I have intel. Lona Vigi, celebrity hair stylist and creator behind Witherspoon’s bombshell waves at the recent Screen Actors Guild Awards, revealed every product responsible for the actor’s head-turning volume.

Key products used hail from Frédéric Fekkai, a salon brand created by the eponymous celebrity stylist. Perhaps most notable among the lineup, at least as it relates to volume, is the Fekkai Clean Stylers Root Lift Volume Spray — a thickening mist with a long-lasting hold worthy of a spin on the red carpet. Moreover, the mist is a mere $13 at Amazon. 

The Fekkai Clean Stylers Root Lift Volume Spray is a mistable styling liquid that adds visible plumpness and height to hair. Designed for all types and textures, including limp, lackluster strands, it works almost instantly, lifting hair at the root and holding it in place to create height. The mist also offers longer-term benefits, the likes of which actually improve hair health.

Housed in a small, spray-top bottle, the volumizing mist dispenses via a targeted nozzle, designed to direct the product onto a specific area: the root. A few spritzes on damp hair, prior to blow drying, paves a path to a fuller-looking mane post-styling. All the while, the formula protects hair from damaging hot tool heat, up to an impressive 450 degrees fahrenheit.

The mist’s fullness-inducing effect lasts for up to 48 hours, per the brand — even amid humid, sticky air. Residue-free, flake-resistant and “non-sticky,” per the brand, the lightweight liquid relies on root-hoisting copolymers, which provide lasting lift.

In addition to the “non-sticky volume” Vigi cited in a press release, she chose the product to “combat humidity.” As for the longer term benefits: Expect stronger hair with continued use. This thanks to a peptide blend, designed to nurse weakened hair to health, and, in turn, stymie excess shedding. Similarly, plant-derived proteins lessen hair breakage — which, ultimately, allows for longer growth. 

Shoppers are impressed by the strand-thickening spray. According to one reviewer with “fine, limp hair,” the mist delivers “all-day lift,” and smells fantastic to boot. Similarly, another reviewer, with “thin, flat hair,” deems Fekkai’s product among “the top” volumizers they’ve used, noting that it “lift[s] at the roots.” Furthermore, the shopper says, this lifting effect “lasts” until their next hair wash — “even after several day[s],” they say. Finally, another fan praises the mist as “the best root-lifter.” Bonus: It “controls static cling.” 

To fatten feeble strands in minutes and strengthen weak hair over time, shop the root-lifting spray behind Witherspoon’s voluptuous locks, the Fekkai Clean Stylers Root Lifting Spray, for $13 at Amazon.
