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.

Ingredient Deep Dive

Ingredient Safety 9/10

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.

The Bottom Line

Sienna Naturals

9 Independence

Sienna Naturals was founded by Hannah Diop to address a significant gap in the clean beauty market: there were almost no truly clean haircare brands formulated specifically for textured, coily, and curly hair. Most natural haircare for textured hair still relied on silicones, sulfates, and heavy oils that build up over time.
