Tess Petrie first picked up a pair of scissors at fifteen years old.
She is a third-generation hairdresser, the granddaughter of a hairdresser, the daughter of a hairdresser, and someone who has never known a life outside of this craft. She began her apprenticeship at fifteen, was named Apprentice of the Year, and built a career that took her to the international fashion weeks of London, New York and Paris, to the editorial pages of magazines including Marie Claire, and eventually to nine salons across Brisbane, including Headquarters on James Street, her most successful and most beloved.
Nearly four decades. Thousands of consultations. An extraordinary career by any measure.
And yet, it was what she witnessed behind the chair that stayed with her most.

People don't come in and say they're losing their hair. They say things like "my hair just isn't the same anymore". There is confusion in those words, and something quieter underneath. A sense of losing part of themselves.
Across thousands of appointments, Tess noticed the same patterns. Thinning, breakage and increased shedding, appearing alongside stress, hormonal shifts and the natural process of ageing. Almost always in people who were already doing everything right on the outside, and still not getting the results they needed.
Her own journey
When Tess lost her sister, grief changed her in ways she hadn't anticipated. One of them was visible. The stress and loss that followed led to her own experience of hair thinning, something that confronted her professionally as much as personally.
She understood the biology. But understanding something and being able to help it are two different things. Tess found herself in the same position her clients had always described.
So she went looking for what was actually missing. Not on the scalp, but within the body. What she found became the foundation for everything that followed.
Because the answer was never going to come from the outside.
Tess will not be hairdressing forever. But she wanted to leave something meaningful behind. Something created with experience, empathy and responsibility. Something that could support people beyond the appointment, beyond the salon, beyond what she could offer with her hands.
When people feel good about their hair, they feel good about themselves. That has been true in every salon she has ever worked in, across every decade of her career.
Synergy Science is part of that legacy.
