“The objective . . .” of a 2018 research project from the Fashion Business School, London College of Fashion, and Dr Chris Gummer at Cider Solutions Ltd., Chilworth, UK, was “ . . . to assess the frequency and magnitude of combing forces on individual hairs against a hypothesis that fibres on a consumer’s head rarely experience significant loads during routine combing.”
So, what is the load on a human hair during combing?
“During combing, individual fibres may not experience any significant load and are unlikely to experience repetitive loads >10g “
