In fact, Yvonne has treated her hair so frequently that she counts herself lucky to still have golden locks.
"I don't deserve hair -- really the things I do to it! I'm back to blonde now. I'm quite happy with it at this length and I do prefer blonde, I think it suits me," she said.
It makes sense that Yvonne is so adventurous with her hair -- the mum-of-three was working as a receptionist at a hair salon on Grafton Street when Assets boss Derek Daniels spotted her.
"She had this long, curly, wavy blonde hair and as soon as her picture test came back, she got started," Daniels said.
