Our Commitment

Excellence in Formulation

We formulate and produce our products in-house, ensuring total quality control at every stage. Our formula commitment ensures formulas are safety-tested, dermatologist-tested, and consumer-validated. We prioritize ethical, sustainably-sourced and naturally-derived materials. Our formulas are vegan, gluten-free, paraben-free, sulfate-free, and cruelty-free. Rooted in science, all formulas are made-to-order in our one-of-a-kind facility in the US.

Our Commitment

Excellence in Testing

Beyond premium quality and safety, our products undergo rigorous testing, meeting or surpassing industry standards. They are dermatologist-tested for sensitive skin, stability and microbiology tested. We incorporate independent lab tests, visual inspections, and performance evaluations at our in-house salon. Instrumental testing ensures our haircare products deliver proven results.

Our Commitment

Excellence in Ingredients

We meticulously select ingredients from trusted suppliers, adhering to strict cosmetic regulations. Beyond this, we formulate retail products to meet retailer clean standards, such as Clean at Sephora and Target Clean. Each chosen ingredient is rigorously assessed for safety, with our formulas vetted by expert toxicologists.

Minimizing our footprint

Innovation Meets Responsibility

Every step we take is intentional, aiming to minimize our environmental impact. We use post-consumer recycled materials for our product bottles and shipping boxes. Our packaging supplier holds SFI Certification, ensuring sustainable forestry practices in material sourcing. We offer customers the option to forgo pumps and minimize secondary packaging whenever possible. In our production facility, we've implemented energy-saving processes and the size of our shipping boxes is designed to minimize waste.


Innovation Takes Shape

In our advanced production facility, our proprietary algorithm enables us to create a unique formula every 13 seconds. This facility is designed for comprehensive customization, accommodating various parameters including fragrance, color, size, and bottle type. As a result, your haircare is crafted to your specifications, bottled, and shipped directly to you. Moreover, you can adjust your formulation as your needs change over time. One constant remains: every bottle will distinctly represent you. It's that personalized.
