From the salon chair: what 39 years taught Tess about hair health
There is a particular kind of knowledge you only get from doing something for a very long time. Tess Petrie has spent thirty nine years behind the chair, working with hair of every type and every stage of life, for clients of all kinds. Along the way she has noticed patterns that no single appointment could reveal, and it is that long view that eventually led her to found Synergy Science and create Hair Formula.
Here is some of what those years taught her.
Hair reflects more than what you put on it
Tess will tell you that for a long time, the industry focused almost entirely on the outside. Shampoos, treatments, styling. All of it useful, none of it the full story. What she observed over the years is that hair is also a reflection of what is happening within, and that the condition of someone's hair often tracks alongside their overall nutrition and the season of life they are in.
That realisation shaped how she thinks about hair health. Care from the outside matters, but it works best alongside support from within.
There are no overnight answers
Decades of watching hair grow, one client at a time, gives you a healthy respect for the timeline. Tess is the first to say that hair does not change quickly, and that the people who see the most are the ones who stay consistent and patient rather than chasing quick fixes. It is a message that runs against a lot of the noise in the beauty world, and it happens to be true.
Everyone's hair deserves the same thoughtfulness
One thing Tess is firm about is that hair health is for everyone. Hair changes across life for all of us, and the fundamentals, good nutrition, gentle care and patience, do not discriminate. That inclusive view is baked into how she approaches her work and how Synergy Science thinks about the people it is here for.
Why she built Hair Formula
When Tess created Hair Formula, she wanted to bring the from-within thinking she had developed over her career into something considered and simple. A formula built around the nutrients hair draws on, in measured amounts, designed to support hair health from within when dietary intake is inadequate, taken as an easy once-a-day ritual.
It is the product of a long career spent paying attention. And if there is one thing thirty nine years in the chair will teach you, it is that the quiet, consistent things are usually the ones that matter most.
