If you want to show how your products deliver volume and body to hair, then you might consider performing a tress volume test.

Testing involves analysis of images to track changes in tress dimensions and volume, both before and after treatment with products, under climate-controlled conditions. High quality photographic images are acquired that characterize the shape of the tresses over time. The volume dimensions are measured from the captured images and analyzed using bespoke TRI software.

The hair volume test works best for styling products that create hold. The hair volume test can also be performed with a sebum-treated baseline to characterize volume via cleansing, ideal for shampoos or shampoo and conditioner regimens.
