Sienna Naturals 9 · 9

Reviewed Feb 26, 2026

Clean haircare designed specifically for textured hair. Black woman-founded.

Why We Trust This Brand

Sienna Naturals fills a crucial gap: genuinely clean haircare for textured hair. Most "clean" haircare brands formulate for straight or wavy hair, while most textured hair brands still use conventional ingredients. Hannah Diop built a brand that does both — clean ingredients in formulas that actually work for coily and curly hair patterns.

Ingredients & Safety

Gentle plant-based cleansers, hyaluronic acid for hydration, botanical extracts including blue tansy and moringa. Free of sulfates, silicones, parabens, phthalates, mineral oil, and petroleum. Formulated specifically for the porosity and moisture needs of textured hair. Scored 9 because some products use mild preservatives and naturally-derived emulsifiers.
