Crambe maritima, also known as “sea kale”, is a perennial plant that grows primarily in Brittany and on the English Channel coastline. It adapts well to the inhospitable environment presented by the swaths of stone along these beaches. This plant has been known to humans for millennia and, just like its cousin the cabbage, it can be used for culinary and cosmetic purposes. Its adaptogenic molecules and its original amino acids composition give it anti-free radical properties that protect the hair from external aggressions and stress caused by styling tools. Because it is a protected species, we use a farmed variety.
