Hannah Diop is changing the luxury haircare industry with a simple belief: textured hair should receive the same care as skincare. Her brand, Sienna Naturals, has gained recognition in high-end salons and on international fashion platforms. The journey began when she faced her own struggles with curly hair maintenance.

Diop’s inspiration struck in Minneapolis after swimming left her curly hair difficult to manage. Frustrated by the lack of effective products, she decided to create her own. Before this, she had built a career at McKinsey & Company and earned an MBA from Wharton.

Sienna Naturals was founded on three principles: clean ingredients, proven results, and deep respect for textured hair. The brand’s mission goes beyond products—Diop aims to shift global beauty standards by elevating African hair techniques as the gold standard. In 2025, her work earned a $100,000 grant from Sephora and the Fifteen Percent Pledge. This financial boost further solidified Sienna Naturals as a leader in inclusive luxury haircare.

Today, Sienna Naturals stands as a celebrated name in premium salons and fashion circles. Diop’s vision has turned a personal challenge into a movement redefining beauty norms. The brand continues to grow, offering high-quality care for textured hair worldwide.
