Splitting hairs: Science of biomechanics to grasp of unhealthy hair days


Lecturers are sometimes accused of “splitting hairs,” however a group at Trinity Faculty Dublin has now devised a machine to do exactly that. All of us have a nasty hair day every so often, and break up ends are a typical drawback. Nonetheless, the science behind this type of hair injury is poorly understood, which is why the Trinity group, led by Professor David Taylor, is investigating this knotty drawback.

Prof. Taylor’s analysis within the Trinity Centre for Biomedical Engineering covers all types of pure supplies, from human bone to seashells however he had by no means labored on hair. So, when main cosmetics firm L’Oreal approached him, he was blissful to just accept the problem.

Working with colleagues, he developed the “Transferring Loop Fatigue machine,” which has been expertly designed to recreate what occurs when tangled hair is combed out. The outcomes have simply been revealed within theJournal of the Royal Society Interface Focus.

Two varieties of hair have been examined: some from an individual who suffered from break up ends and a few from an individual who did not. Utilizing the machine, the group was capable of generate splits in each varieties of hair, however the splitting-prone hair break up extra shortly and generated splits that have been for much longer. Moreover, when bleached, the hair from the one that did not endure with break up ends began to separate equally to the splitting-prone pattern.

Isobel Duffy, one of many researchers on the group, added: “We have been amazed at how nicely the machine labored — typically, a single strand of hair break up into two alongside its complete size, in the identical manner that hair does when some individuals dry and comb it earlier than beginning their days. Now we are able to create splits in a reproducible manner we are able to go on to review why some individuals’s hair splits and a few does not, and higher examine the results that some beauty remedies have on hair high quality.”

Prof. David Taylor stated: “This work constitutes a primary step in growing a scientific strategy to higher understanding the biomechanics of hair splitting. It paves the best way for future research, together with a extra complete experimental programme involving a bigger variety of donors with completely different hair varieties — together with curly hair — and extra detailed research that might incorporate the results of humidity, temperature and completely different remedies.

“Hair is a posh materials and it’s stunning how little we find out about it. In time our work might change that, with implications for the cosmetics business and the hundreds of thousands of individuals throughout the globe that wish to take first-rate care of their hair.”

One other group member, Robert Teeling, added: “After I began as an Engineering scholar in Trinity I did not suppose I’d spend my Masters’ 12 months testing hair. However it turned out to be an amazing mission: I designed and constructed a brand new kind of machine from scratch and made an actual contribution to science. I learnt that hair is a fabric like another: it might break by means of mechanical forces, on this case once you comb or brush it, and it is delicate to the way you deal with it.”
