Bonnie with mum Wendy Pullan. See SWNS story SWNJhair. A schoolgirl bullying victim who went completely bald due to relentless abuse has received a £5,000 “life-changing” hair loss treatment just in time for Christmas. Brave Bonnie Pullan, 11, was fitted with a prosthetic hairpiece created from a 3D mould of her head which is sealed in place using long-lasting adhesive. The non-surgical treatments, called a CNC medical hair replacement system, fits onto the top of Bonnie's head, making it very hard to tell that it’s a prosthetic. And it means she can wear the advanced wig for years without having to take it off, which her mum Wendy, 38, says will help her get her confidence back.
