One of the world's most innovative and respected hair stylists, Guido Palau has made his mark on the world of fashion by taking traditional styles and giving them a rebellious twist. Guido's creative eye is highly sought after by designers and editors alike; and his collaborations with renowned photographers such as Steven Meisel and David Sims over the past 30 years have resulted in some of fashion's most iconic images.

Guido's work appears regularly in the pages of British, Italian, French and American Vogue, as well as W Magazine. He is equally omnipresent on the runways of New York, London, Paris, and Milan, where he executes his vision for diverse fashion houses such as Prada, Dior, Valentino, Loewe, Schiaparelli, Fendi, Versace, Ralph Lauren and Miu Miu among others.

Guido's elevation of hairstyling into an art form was more apparent than ever before in 2011, when he was asked to design the head treatments for the Metropolitan Museum of Art's Costume Institute exhibition Alexander McQueen: Savage Beauty. To date, this is the Met's most viewed fashion exhibition. This exhibition travelled to the Victoria and Albert Museum in London in 2015, where Guido designed new head treatments for a portion of the exhibition along with his archived treatments from 2011. In 2012, the Metropolitan Museum of Art engaged Guido’s services again to create masks for their Costume Institute exhibition Schiaparelli and Prada: Impossible Conversations. The MET commissioned him once more in 2013 to design treatments in an array of vibrant colors for the Costumes Institute’s Punk: Chaos to Couture.

In 2016, Guido’s hair designs were featured in the Cooper Hewitt, Smithsonian Design Museum's fifth Design Triennial. The exhibition highlighted the intersection of beauty and contemporary design and featured work by outstanding artists and designers from around the world.

His first book, Heads: Hair by Guido, was published to much acclaim in 2000 and features a decade of stunning head shots, a testament to hair as style's most defining signature. His second book, Hair, published in 2014 is certainly a collectors item with 70 unique, avant-garde hair designs in demand worldwide. In 2021, Guido published #HAIRTESTS, further documenting his prolific and sculptural approach to hair. Guido was appointed as Creative Director of Zara Hair in 2022.
