Eight-year-old Persephonie Bradbury will have her hair chopped to donate to the trust, which provides wigs for children undergoing cancer treatment.
Persephonie, a pupil at Holme Hall Primary School, says she wants to ‘put a smile on another child’s face’.
Dad Jono Bradbury said: “We are so proud of her. She first wanted to donate her hair to the trust about two years ago but we told her to wait a couple of years.
“Her hair is really long at the moment and I always call her my little Rapunzel.
“We decided to not just donate Persephonie’s hair but also to set up a JustGiving page so people could donate.
“It had raised more than £300 in just a day-and-a-half and we set the target at £550, which is just over the price it costs for the trust to make a wig.”
Persephonie is now booked in for her transformational hair cut on March 25 at Harleys Hairdressing, on Chatsworth Road, Chesterfield.
Her family, including dad Jono, mum Rachel and brother Gabriel, will be supporting Persephonie on the day.
She says: “My hair makes me happy and I want to make some one else happy, and I think they deserve to smile so please help as well by donating as little or as much as possible.”
