This month, the gorgeous, honey-infused hair-care brand, Gisou, launches in the UK. The entire range of products — which includes shampoo, conditioner, treatments, and stylers — is lovely and smells divine, but we're especially obsessed with the Gisou Honey Infused Hair Mask (£45), which is intensely hydrating thanks to the honey (which is sourced from the founder Negin Mirsalehi's family bee garden in the Netherlands), as well as sunflower seed, castor, and coconut oils. We also appreciate the large, 250 millilitre-sized jar that really does last forever.
