Founded by Kadidja Dosso after her severe allergic reaction to traditional braiding hair, Philadelphia-based Dosso Beauty makes clinically tested, non-toxic and hypoallergenic synthetic braiding hair for safer protective styling. The Black woman-owned company, established in 2018, also develops hair-care products and operates The Dosso Beauty Experience, a luxury braiding salon and retail store in its hometown. Dosso Beauty says it has served more than 200,000 customers and its hair is free of heavy metals.
