Celebrating our History | The Sienna Naturals Journey

Your hair, your style, your choice. At Sienna Naturals, we’re on a mission to empower you with the products you need to make your hair and scalp the healthiest it has ever been. For too long, products have worked against your hair, not with it, and have failed to understand your specific hair needs (not to mention the use of harsh and toxic chemicals). We know your struggle, and that’s why Sienna Naturals was created. Learn more about our journey below!

The Big Idea
After her own struggles with trying to find a clean formula on the market for her hair needs, and learning about higher rates of dermatitis and scalp irritation in Black and Brown communities, Hannah heads to the public library to dig deeper. Shocked and disappointed by options on the market, she becomes determined to find the best ingredients to address this issue head on.

Retail Launch

Sienna Naturals launches at Nordstrom. Seeing Sienna Naturals on their shelves nationwide brings 8 years of hard work and efforts to life, reminding us that our struggle matters and can lead to some beautiful results. Sienna Naturals is now poised to deliver clean and effective hair care that actually works for textured hair, and can be found right in your neighborhood or delivered to your door.

Sienna Naturals becomes the first dermatologist-tested, approved, and responsibly sourced suite of products specifically designed for textured hair. In addition to ingredients passing a high bar for plant-based origins and safety, Sienna Naturals establishes protocols to dermatologist-tested every product we sell. Being dermatologist tested means that all Sienna Naturals formulas undergo clinical trials conducted by an independent laboratory and overseen, evaluated, and approved by Board Certified Dermatologists and Registered Nurses. Each product is tested on more than 50 human subjects over the duration of several weeks before they are determined to be non-sensitizing and non-irritating to the skin.

First Styler Introduced

After year of development, Dream Curl Cream was launched, becoming Sienna Naturals first ever styling product. A historic accomplishment as this category is dominated by synthetic ingredients because that's what traditionally curls the hair. The Sienna Naturals team challenged themselves to create something better using the power of plants. Dream Curl Cream has been a best seller since.

Styler Line Expanded

After the success of Dream Curl Cream, the Sienna Naturals community was itching for additional cleaner styling options. Dream Curl Mousse was launched with amazing reception.

Retail Launch

Sienna Naturals launched in Credo Beauty in store and online. Credo is where all beauty is clean beauty. In fact, The Credo Standard is the highest clean standard in beauty retail and all Sienna Naturals products meet this standard. This partnership feels incredibly aligned to both Sienna Naturals and Credo and their values and commitment to safe and efficacious ingredients and products for hair, scalp, face, body and the environment.
