By leading with science, we engineer breakthrough solutions for your real-world hair problems. ‌ We are the science, you are the Living Proof.

In 2005, an unlikely combination of biotech scientists and renowned hair stylists came together to pioneer a first-of-its-kind haircare philosophy based in science. Our mission was to create inventive solutions designed to solve real-world hair problems.

Today, Living Proof is Science in Action, which means we’re at the forefront of scientific discovery, inventing and iterating on the latest innovations in haircare that deliver game-changing results for all types and textures.

More on Science in Action: Science is always evolving, and therefore, so are we. Staying ahead of the latest technological advances requires us to constantly raise the bar for ourselves and continually develop new products—and reformulate existing ones—to be even better than we believed possible.

120 global patents, 450+ formulas, 44 products, 200+ awards, and 16 years later, we continue to put research at the forefront of our formulations. Every single product is rigorously developed and tested at our in-house laboratories in Boston—not too far from our original home at MIT University.
