ABOUT US
Gisou is born out of a passion for bees, haircare and natural beauty. Based on a six-generation beekeeping heritage, each Gisou product is inspired by and made with the finest, sustainably sourced ingredients from our very own Mirsalehi Bee Garden. With this method, our founder Negin and her father continue the family tradition of beekeeping. Our hair care and complexion products harness the transformative benefits of Mirsalehi Honey and rich botanical sources, selected to enhance ones natural beauty.

We are committed to a bee-friendly & sustainable production method that puts the Mirsalehi Honey Bees first, not only for the sake of the bees, but the greater ecosystem as well. In the upcoming years, we intend to continue to develop high-quality honey infused beauty products as we develop a globally renowned label and raise awareness about the importance of a healthy bee population.

We have been experiencing double digital growth YoY and have established ourselves as a leading hair care line across our global retailers such as Sephora, Selfridges, Mecca, and Harrods. We are currently available in over 40 countries and are on an explosive journey of growth as we launch in new markets, open additional channels and focus on building our team internationally.

Our team is the heart of our business, without an incredible team we would not be where we are today and where we dream to go tomorrow. Being a part of Gisou is for those who are passionate, ambitious, hard working, agile and approachable. Join us on this epic journey!
