Instrumental evaluation is a key approach in analyzing where a material or product resides on the performance spectrum. TRI offers a broad variety of analytical techniques to access the functionality of raw materials and finished products on  hair. The test information can be used to aid in modifying material composition, enhance end product formulations, support/substantiate claims and execute research studies. Study plans for testing are generated with the goal of best representing the material or product, on the best suited substrate, using the optimum equipment and method in order to achieve the desired outcome.
