Nothing ever came of it unfortunately, but at the time I seem to recall the idea was to conduct experiments to determine which of a number of candidate materials would make the "best" standardised hairlike substance for use with the HHT.

Personally, I'm not really sure it matters all that much. I can see the benefit of a "standard" hair, especially for education and training purposes, but we've managed all these years and I am sure will manage for many more without one so long as people appreciate that HHT results are not generally transferrable to others except in the most vague sense, and that they need to generate their own personal data through experience and repetition in order to use this test effectively.

So along with the equipment, we will need schools to teach the correct methods for standard testing. Such as speed, relative angle, ambient temperature, blade and standard hair temperature and relative humidity. Or we could just shave test and decide from that
