Sienna Naturals is a Los Angeles–based clean haircare brand founded in 2012 by Hannah Diop and later joined by actress Issa Rae as co-owner and ambassador. The brand focuses on plant-based solutions for textured and curly hair, combining natural ingredients with dermatological science. Its range includes shampoos, conditioners, and treatments that restore moisture, strengthen strands, and promote scalp health. Sienna Naturals avoids sulfates, silicones, and synthetic fragrances, offering clinically tested, vegan formulations. The brand stands out for its focus on scalp care as the foundation of hair wellness, a concept often overlooked in textured haircare. What makes Sienna Naturals distinctive is its science-meets-culture approach — addressing the specific needs of textured hair while promoting authenticity and representation in beauty. The brand has quickly grown into a leader in the clean-textured haircare movement.
