The build-up of static electricity in the hair, and hence flyaway, can be an issue in dry air-conditioned buildings, during low humidity winter months and is often problematic during heat styling.  If you want to show how your product, or hair styling device, reduces flyaway it might be interesting to measure hair static levels.

Conditioner products can be very effective at reducing static electricity build-up, as can the use of different types of combs.  In this test, hair tresses are brushed on a custom-built device. An appropriately placed sensor provides real-time measurement of the static build-up and decay.
