Serge Normant cuts my tresses, but he’s not the only guy in my hair’s life. I’ve long adored the Paris colorist Christophe Robin for his masks and shampoos, and now I’ve fallen for his Regenerating Hair Finish Lotion ( $48, sephora.com), which uses hibiscus vinegar to remove residue from the scalp and hydrate color-treated locks. I also can’t do without Kevin Murphy Free Hold Styling Creme ($25, kevinmurphy.com.au), which keeps flyaways at bay with carnauba wax and yerba mate. And then there’s hair guru Michael Gordon (founder of Bumble and bumble), whose Isle of Roses Rose Hair Oil ($50, isleofrosesnyc.com) is my new secret weapon. “Most people don’t wash their hair every day,” Gordon says. “Using an oil this light freshens up that five-day-old blowout.” Five-day-old blowout? Moi?!
