The 38-year-old Sunshine Coast star has received online backlash about her appearance.
Speaking to Chrissie Swan at the Nova 100 MAFS party Heidi revealed she’d chosen to grow out her hair colour while she was filming the show.
“I decided when I was going on the show, that I would grow out my regrowth. I had blonde hair for many years and I was sick of having blonde hair and having to do it all the time,” she told Chrissie.
“And I thought, '’I’m going to go away for three months and I'm going to have it done'’ and then I went, '’No I’m going to grow it out,’” she insisted.
