RT18: Our Proprietary Active Ingredient Blend Transforming Haircare

It's no secret that at Sienna Naturals plant-based, scientifically-proven ingredients take center stage. For over a decade we've been committed to researching ingredients and developing formulas that harness the power of plants and actually work to address our top hair concerns. We refer to our formulation approach as Rooted Technology and  RT18™ is the proprietary ingredient blend behind our superior performance and award-winning wash day and styling essentials. 

What are Active Ingredients in Haircare?

Active ingredients, in the context of haircare, refer to the key ingredients in a product that individually, or when blended with other ingredients, provide specific benefits to the hair and scalp. These ingredients play a crucial role in addressing hair concerns and achieving desired style outcomes. Our plant-based formulas utilize a proprietary blend of 18 active ingredients that hydrate, reduce hair loss, and improve curl pattern, repair damage, and reduce frizz. These 18 ingredients, also known at RT18™, were each carefully chosen for its unique properties and contributions to overall hair health.
