Living Proof prides itself on our commitment to rigorous testing that is unparalleled within the haircare industry. By strictly following the scientific method, our experiments are thoughtfully designed and our results unbiased.

Performance + measurement testing

Our scientists are committed to holding our products to the strictest of standards by using a variety of industry and hair-specific tests, such as Tensile Strength, alongside advanced analyses like Differential Scanning Calorimetry, which measures the efficacy of repair, and SEM (Scanning Electron Microscope) Imaging to see what's really left behind on strands.

Safety and quality

Safety and quality are always at the backbone of every single formula we make—all 450+ of them to date. Through quality control procedures, we ensure microbiological efficacy and assess every single formula.

Performance and consumer perception

However, it's equally important that we keep you—our consumer—involved in our testing protocols.
