It will be hair today gone tomorrow for Marianne Hales.
She has decided to donate her waist length hair to charity CLIC Sargent which makes wigs for children with cancer.
The 34-year-old, who has Down's Syndrome, hasn't had a haircut since she was a little girl.
She told UTV: "I will miss it. I do love it."
Marianne was inspired to get the chop after the disease claimed the life of her father.
With the help of her mother Anne, who also suffered from cancer, Marianne is also hoping to raise vital funds for the charity.
Anne explained: "It's very selfless for anybody to do what Marianne is doing but to me I am extremely proud of her because she has Down's Syndrome and has a fantastic understanding of why this is needed.
"Cancer is something that is not strange to the family but I was actually quite surprised when Marianne came up with this idea.
"I got in touch with CLIC Sargent because they are doing a big appeal at the moment for homes from home and trying to build two homes, one outside Royal Victoria Hospital and one outside the City hospital."
Marianne is due to have her hair cut on 3 August and it is hoped she will be able to provide wigs for two children.
