Help us to give Hair and Hope to children and young people by providing wigs and funding vital research into childhood cancers.
The charity provides around 2,000 real hair wigs every year to children and young people who have lost their own hair through cancer treatment or due to other conditions such as Alopecia.
Each wig costs £550 to provide. Our wigs make a huge, positive difference to the lives of each recipient. We rely on events like these to help fund our free wig provision service.
The Little Princess Trust is also now one of the largest funders of childhood cancer research in the UK and has committed more than £22 million to projects focused on finding kinder and more effective treatments for childhood cancers.
