How Did We Clinically Test the Shampoo and Conditioner Bars? 

We worked with a US-based, independent lab based out of southern California that has conducted hair tress testing since 1931. We designed our products to be effective than leading bottled shampoo, but we wanted to objectively test our products and put some numbers behind the information we’ve observed from our own research during testing. The lab used top of the line testing equipment to verify our product efficacy on human hair in the following areas: Volume, Shine, Softness & Moisture, Strength, and Frizz.
