Splitting Hairs: A Journey into Bad Hair Days and the Biomechanics Behind Them

We all experience the occasional bad hair day, often accompanied by the dreaded split ends. But what exactly causes these unsightly hair splits? A team of researchers from Trinity College Dublin has taken a novel approach to understanding this common hair issue, employing the science of biomechanics.

A Mechanical Test for Hair Health

Led by Professor David Taylor, the team devised a specialized “Moving Loop Fatigue Machine” designed to mimic the forces applied when combing tangled hair. This machine subjected two hair samples to a series of mechanical tests, one taken from an individual prone to split ends and another from someone without the issue.

Understanding Splitting Tendencies

The results were revealing. The splitting-prone hair exhibited more rapid and extensive splitting compared to the healthy hair sample. Interestingly, when bleached, the normally healthy hair began splitting similarly to the prone sample.

Unraveling the Splitting Puzzle

“We were astonished by the machine’s effectiveness,” said Isobel Duffy, a researcher on the team. “Single hair strands would often divide cleanly along their entire length, replicating what occurs in real-life split end scenarios.”

This breakthrough enables further exploration into the factors influencing hair splitting tendencies. The team aims to study why some individuals experience more splits than others and investigate the effects of cosmetic treatments on hair quality.

Hair as a Biomechanical Enigma

“Hair is a remarkably intricate material,” said Prof. Taylor. “It’s astounding how much we still don’t know about it. Our work could revolutionize our understanding of hair biomechanics, ultimately benefiting the cosmetics industry and individuals worldwide seeking optimal hair care.”

The Engineer’s Hairy Adventure

“As an engineering student, I never anticipated spending my Master’s year testing hair,” said Robert Teeling, another team member. “However, it’s been an incredibly rewarding experience. I designed and built a unique machine, contributing to scientific advancements. It’s taught me that hair, like any other material, can succumb to mechanical forces and requires proper care to maintain its health.”

This innovative research takes a scientific approach to understanding hair splitting, paving the way for future studies that will unravel the mysteries of hair health and quality.
