The Hair Care Brand That Blake Lively's Stylist Swears By

Blake Lively's long, sun-kissed waves are as iconic as her acting career. Lively has invested a lot of time, care, and money into her locks, which has resulted in some of her best hair moments on the red carpet. One look at Lively's dramatic fishtail braid at the 2012 premiere of the film "Savages" (via Byrdie) or her tousled ponytail at the 2016 Cannes Film Festival (via PopSugar) shows the versatility of her hair. Her drastically changing hairstyles are an extension of her own ambitious personality. She experiments with movie genres the same way she experiments with her hair, and we all love her for it.

Blake Lively is big on using natural ingredients in her hair. In a 2014 interview with Style.com, she revealed one of her biggest hair secrets: sea water (via Women's Health Magazine). "My hair is always better in California than it is in New York, so I got a big water jug and I filled it with ocean, which is probably a really bad idea, but I would put it on my hair, and actually, it worked," she explained. "... It makes your hair a little crunchier and holds it a little better," she added.

Lively's beauty routine is a mix of DIY hacks straight from the fridge — like mayonnaise (via Women's Health Magazine) — and luxury products that keep her tresses looking healthy and glossy. Legendary hairstylist Serge Normant uses this specific hair brand to give her famous hair its volume.

After many years in the beauty industry and styling some of the biggest names in the business, celebrity hairstylist Serge Normant – whose clients include Julia Roberts, Gisele Bündchen and Reese Witherspoon — created his own hair care line (via The Zoe Report). His signature look is all about volume, which explains why Blake Lively's iconic waves are always larger than life and glamorous. Normant shared with Elle how beauty lovers can get maximum fullness without overdoing it. "Find a good volumizing spray," he explained. "You can use it in different ways: Either spritz the product from the hairline to the ends, then blow dry with a round brush, or just apply it to the roots and let it air dry in the summer. If you want even more lift, use a little dry shampoo. Back-combing can also go a long way," he added. His eponymous beauty line also features a volumizing spray — so if you're looking to imitate her beach waves, start there.

During an appearance at Gucci's 2014 'Chime for Change' campaign, Lively switched it up and wore her hair in an artfully "messy" side-swept braid. Hairstylist DJ Quintero told Allure that he used Serge Normant's Conditioner and Dry Oil to moisturize and seal her hair. So all we need to do is add conditioner and dry oil to our shopping carts for hair like Blake Lively? Done and done.
