A 12-year-old girl who raised £1,000 for charity by having her head shaved has been banned from mixing with her classmates.
Charlotte Duggan was shorn to raise money for Breast Cancer Campaign after being inspired by her own grandmother's successful battle with the disease.
But instead of being praised when she returned to Cranbourne Business and Enterprise College in Basingstoke, Hampshire, teachers put her into 'isolation' for two days.
Charlotte was also banned from mixing with her classmates and going out at lunch and breaktimes.
The youngster, who also had the charity's iconic yellow ribbon shaped into her shortened hair, said: "I only decided to shave my head at the beginning of August so I could not have asked the school for permission.
"Isolation is supposed to be for bad behaviour. I was upset and I don't know how it will affect my education."
Charlotte's mum, Kerry, 31, added: 'I couldn't believe it when she told me what had happened. She should be proud of what she has done. She should be able to hold her head up high.
"I think it's absolutely ridiculous that they made her feel like she had done something wrong."
However, the school's headmistress Betty Elkins insists she asked Mr and Mrs Duggan if the ribbon pattern could be covered up during school time, which they refused.
She explained: "We asked if Charlotte would be able to cover up the pattern but that wasn't something her parents thought was acceptable.
"When Charlotte was in isolation, she was working on an assembly about her fundraising which she will be presenting to the whole school. This will hopefully mean she will raise even more money."
All pupils received a letter before the school holidays reminding them about appropriate hairstyles.
