Three years ago, when Valerie Grandury was taking a bath, she had something of an aha moment: “I looked at all the plastic bottles that were lining my tub and thought, Oh, my God,” recalls the founder of the Los Angeles–based skin-care line Odacité, who soon discovered that an estimated 552 million plastic shampoo bottles end up in landfills every year. “I thought, There has to be a way to make a solid shampoo that gives you the pleasure of your regular shampoo without the plastic.” In 2020, she finally achieved that vision with the launch of her first hair-care offering, a palm-size vegan shampoo bar made with coconut powder, cupuaçu butter, and no added water—an environmentally conscious approach that creates an ultra-concentrated, compact cleanser, which can last up to 80 washes.
“Eliminating water is the most effective way to deliver a great plastic-free shampoo without sacrificing convenience,” says By Humankind cofounder Joshua Goodman, whose all-natural cold-processed sticks arrive in a recycled-paper box alongside a quick-drying shower dish to preserve their lifespan. “Your hair has to get used to the solid format,” concedes the French colorist Christophe Robin, whose own barre is enriched with hydrating aloe vera. But, he notes, after just a few washes, one will appreciate the added bonus of “more texture and hold.”
“Everyone is always surprised that they work so well,” agrees the Paris-based coiffeur Javier Palacio, who custom-makes shampoo slabs out of his studio for those in the know, such as the creative director Clarisse Demory. Plus, he continues, the thick one-of-a-kind formulas, which can take on a myriad of rich colors thanks to their raw, plant-based ingredients, “are also just really beautiful objects.”
