McMillans Hairdressers is a collaboration between colourist Trish Byrne and stylist Jane Cooper. After building careers as specialists in their fields, they chose to combine their skills at McMillans to provide a personalised service that delivers high-quality, sustainable hair. Trish and Jane started working together in the late 90's in the iconic McMillans King Street salon. After years working together they went overseas to continue their careers in Tokyo and the UK.
In 2004 Trish took over McMillans and teamed up with Jane once again, operating from the Old Boans Warehouse salon East Perth.
In December 2020 they combined to create the new McMillans salon in Mount Lawley. The industrial-inspired design reflects their values of quality and simplicity, allowing their work to be the centre of attention.
