Olivia Williams donated more than six inches of her hair to The Little Princess Trust after having the chop on Saturday.
The six-year-old Ysgol Llywelyn pupil from Rhyl took on the feat to help poorly children.
She even managed to raise more than £1,000 through sponsorship, with money still coming in.
Today, Olivia carried out her pledge at Morgan’s Hair and Beauty on Prestatyn High Street.
She said: “My hair is very long and I asked my mummy if I could have it cut short so that I can give it to the charity that makes wigs for poorly little children.
“My hair can easily grow back and I want to be able to help children who don’t have any.
“It was nice that so many people sponsored me too.”
