Dutch blogger Nagin Mirsalehi and her baby boy

The beauty entrepreneur behind a hugely popular haircare brand has spilled the secrets behind her effortlessly bouncy locks – and the honey-infused oil she swears by all year long. Negin Mirsaleh is the Amsterdam-based founder of Gisou, a honey-infused line inspired by her parents; Negin’s father is a beekeeper and her mother, a hairdresser. The company’s hero product is the Honey Infused Hair Oil, which is enriched with Mirsalehi Honey from the family’s Mirsalehi Bee Garden. As honey is a natural humectant, it retains hair’s natural moisture balance, resulting in healthy, soft and shiny locks.
