After her son Ryan's diagnosis in March 2015, Karen wanted to show her support by undertaking the Big Buzz challenge as a way of saying thank you to CLIC Sargent.
Karen, from Kent, raised over £670 from her head shave for CLIC Sargent.
And Ryan bravely took on the first cut for his mum!
She said: "The first shave felt really weird but after that it was fine. I was looking forward to seeing my new look."
