Haircare brand Hair Syrup was founded in 2020 by Lucie Macleod, a then 21-year-old student at the University of Warwick. Frustrated with the lack of effective treatments for her bleached and damaged hair, Lucie began experimenting with natural oil blends in her student kitchen. Her homemade pre-wash hair treatments gained popularity after she shared her results on TikTok, where the brand now has nearly 400k followers). In 2024, Lucie pitched on BBC’s Dragons’ Den and the dragons declined to invest, but this year sales reached £5m up from £1.4m in 2023.
