What Kind of Lipids Do We Seek for Hair?

Updated: Nov 21

600 people have now registered for our fourth series of TRI Talks. Thanks so much for your support! In the third talk, taking place at 1:00 pm (ET), Wednesday 30th November, TRI’s Director of Hair Research, Ernesta Malinauskyte will describe the many different types of lipids in sebum and hair, and how changing the levels of internal lipids may affect hair properties. 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 ‘What types of lipids do we seek for hair?’, takes a deep dive into the composition of hair lipids. As Ernesta describes:


Although lipids are minor hair components, their loss drastically impacts multiple hair properties. With adequate sebum production, we may hope to replenish hair lipids naturally, at least for some hair types. But aging and scalp disorders often interfere with it, therefore, we have to seek external supplementation.

The talk will investigate the similarities and differences in the lipid composition of sebum and hair. It will also attempt to classify the popular oils based on dominating lipid classes and relate the specific classes with the existing evidence. Where do we go from there?
