It Takes A Village with Delina Medhin
S3. EP.60 - Hannah Diop on Clean Hair Care and Co-Founding Sienna Naturals with Sister-in-Law Issa Rae
In this episode of It Takes A Village, Delina sits with Hannah Diop, co-founder and CEO of Sienna Naturals. Building a clean beauty brand for textured hair takes passion, science, and the right people in your corner—and that’s exactly what Hannah has done. With a background in business strategy at McKinsey & Company and an MBA from Wharton, Hannah fused her expertise with her personal hair journey to create a line of science-backed, wellness-driven haircare products.
Hannah shares how the idea started as young as when she was 8 years old, swimming regularly and having frustrations with her hair after training. Since then, she has always had the idea of the right kind of hair product in the back of her mind. Her experiences later on at Howard University, HSBC, Wharton, and McKinsey & Company shaped her confidence in her idea, which eventually led to the launch of Sienna Naturals. We also dive into her partnership with Issa Rae, the development of the Sienna Naturals products, and why wellness is a key ingredient in both beauty and entrepreneurship. Plus, she opens up about the importance of having a strong support system—because building something great always takes a village.
If you’re an entrepreneur, beauty lover, or someone navigating the clean beauty space, this conversation is filled with insights on brand building, pitching investors, and creating products that truly make a difference.
