India, from Tunbridge Wells, was diagnosed with hepatoblastoma when she was a child and continues to raise awareness and funds for CLIC Sargent.
She thought Wig Wednesday was the perfect opportunity to get her friends and the Tunbridge Wells Girls' Grammar School involved.
India, Ruby and Phoebe wore a range of wacky wigs for the duration of the day, and collected donations from their friends and family before, during and after the event.
India said: "When I was very young I suffered from hepatoblastoma. I made a fantastic recovery due to the medication and surgery available. I now have no restrictions to my life and will be forever grateful for the treatment that I received.
“My friends and I wanted to raise money for the fantastic work that CLIC Sargent do in order to help more children through cancer, making their experiences with their families bearable."
CLIC Sargent Fundraising Manager Charlie Straker said: “I would like to say a massive thank you to India, Ruby, Phoebe and the Tunbridge Wells Girls' Grammar School for their ongoing support.
“It’s a great example of how simple and easy it is to participate in Wig Wednesday, with excellent results in raising awareness and funds for children and young people with cancer, and their families. I look forward to working with India on future events.”
