Hair and Hope for children with cancer

Over the past 3 years I've been growing my hair out to donate to The Princess Trust who do amazing work making free wigs for children who have cancer. I'll be donating over 12" of my hair on June 2nd, however making wigs is expensive work and it costs The Princess Trust £550 to make just 1 wig for a child in need.

Anything anyone can share towards this goal would greatly appreciated.
