Cleansing Purifying Scrub with Sea Salt by Christophe Robin: Truly, Madly, Deeply

What do these hair oils and styling creams have in common with Stan Smith sneakers and Mansur Gavriel bucket bags? A quiet cool that’s elevated them to cult status.

French colorist Christophe Robin found that his clients often had itchy, irritated scalps after he dyed their hair. So he stirred together kosher salt and water and massaged it on. “It’s an old grandma remedy to help itching, and it was the only thing that worked without dissolving the color,” he says. Five years ago, he asked a lab to mix sea salt and soothing sweet-almond oil. Devotees of his product now include Tilda Swinton, Catherine Deneuve, and Erin Heatherton; many even use it as a shampoo and a treatment for itchy skin. This loyalty is partly why Teresa Mitchell, the founder of beautyhabit.com, has a hard time keeping it in stock. ”Once it took off, it became our best-selling hair product,” she says.
