The Nebulous World of Hair Damage — TRI Talks 2022

Dr Trefor Evans

TRI Institute Fellow

So far nearly 400 people have registered for our fourth series of TRI Talks. In the second talk, taking place at 1:00 pm (ET), Wednesday 26th October, TRI Institute Fellow, Trefor Evans will describe the many techniques and approaches used to describe hair damage and how this damage may be masked or reversed. The on-line seminars are free to join. Click here to register for the series of talks and to access playbacks Click here to log in to the TRI Talks Attendee hub website to watch live and replay

Since starting in April 2020, at the peak of the COVID-19 epidemic, the TRI Talks have regularly attracted hundreds of scientists from all around the world. To look at previous talks go to the TRI Library This year the TRI Talks will feature a series of four, free seminars focussed on the latest developments in hair science, presented by expert speakers from TRI Princeton, and will be available to watch live or on playback. For the first time the presentations will be streamed live from TRI's facilities in Princeton, giving you the chance to feel even closer to the speakers and the event. Questions will be taken from both on-line and live attendees. Also, for the first time, the talks will be captured on a dedicated event website, allowing you to easily replay any talks that you have missed. Ideal, for colleagues in different time zones! Talks will be held on the website for 2-3 months, after which they will be transferred, as usual, to the TRI Library.

The next talk, titled ‘The nebulous World of Hair Damage’, tries to pin-down for attendees, what hair damage really means. As Trefor says:

“The expression “hair damage” is used ubiquitously, and rather haphazardly, throughout our industry. It is, of course, first and foremost a consumer expression, used to denote that their hair has developed undesirable properties. As scientists, we understand that the complex structure of hair fibers can indeed degrade as a result of everyday habits and practices; but the nature of this breakdown is myriad and occurs to differing degrees depending on the insults involved. Therefore, generic use of this expression is hugely nebulous and sidesteps any specificity about underlying causation.
In the lab, we can perform all manner of evaluations to probe specific alterations to the hair structure and chemistry, which collectively provide for an assessment of the hair’s condition and the issues involved. But, by itself, any method will usually provide information about one specific property which may, or may not, proport to the issue at hand.
This presentation will discuss some of the various techniques and approaches that are used to describe “hair damage” with specific emphasis on the regions of the hair structure being probed; the possible causes of such effects; and, where applicable, how these effects may be masked or reversed.”
