Mel Griffiths thought she had returned to high school when a group of mothers bullied her because of her hair style as she walked her young son to class.
The 28-year-old mother-of-two, from Melbourne, recently dyed her brunette locks a colourful mix of purple and blue.
However, Ms Griffiths didn't expect to hear snarky comments from other parents at her five-year-old son's primary school earlier this week.
'There was a group of three mums looking over and it was pretty obvious they were talking about us,' Ms Griffiths told Daily Mail Australia.
'As we got closer we could hear their comments. One of them said I looked like I had a rainbow on my head - which I didn't take offence to.
'Then another comment was: "I wonder what she's rebelling against." I just thought that was a bit silly really.
The young mum, though furious, didn't retaliate for the sake of her son, Cohen.
'I wanted to play it cool for my son. But also I was pretty stunned to be honest. I thought I had already left high school,' she said.
'He was pretty chilled about it - he just looked at me and asked me if I was OK. He said: "I like your pretty colours mum."
Ms Griffiths had a stern message for the three women, who she said she doesn't know.
'It doesn't matter what somebody looks like, it's what's on the inside that matters,' she said.
