Her proud mum, Marie Middleton, 52, said: “I thought I would cry when Alice had it done – but she was smiling so she wasn’t as nervous as what I thought she was going to be.
“She was supposed to be having it done last Thursday then someone at the school school had a positive Covid test so she had to isolate for 10 days She had all the back and sides shaved with just a bit left on the top.
“She wanted to do it for Cash For Kids. She usually helps out with the Christmas toy appeal we do at the shop and we usually go as a family to sort the toys our for Christmas. It’s like a family charity.
“This year she noticed a lot more children who were hard up and wanted to raise some money so she decided she wanted to give up her hair.”
Meadowhead School held a non-uniform day and donated half of what it raised to Alice’s appeal.
