DR ERNESTA MALINAUSKYTE WILL PRESENT ON:
Scratching the Surface: Lipids, Protection & the Sebum–Microbiome Relationship
The TRI talks are 60-minute on-line seminars on a wide range of topics designed to both inform and inspire new ways of thinking. The fourth talk in the series is by Dr. Ernesta Malinauskyte, Director of Hair Research at TRI, and will give insights into the hidden world of hair and scalp lipids.
Abstract
Ever wondered what really happens to your hair's natural oils when you blast it with heat tools, soak up the sun, or skip a wash day (or two)? In this TRI Talk, we will dive into the hidden world of hair and scalp lipids - sneaky protectors with some truly surprising secrets!
We will uncover fresh insights on how UV and heat target different lipid types (and how we can fight back with better protection). Ever thought about which lipids actually penetrate inside your hair strands? We'll explore that too, and how it ties into the current understanding of hair's built-in "glue"; the cell membrane complex (CMC).
We will also explore an unexpected question: does hair passively collect sebum, or does it “choose” certain lipids? The comparison of sebum and surface lipids from the same heads might change how you think about greasy roots!
Finally, a proof-of-principle microbiome study demonstrating the relationship between sebum lipids and scalp bacterial populations in samples collected 2 days after washing.
