Pupils are breaking the rules this week by having their hair dyed green.

They will have the word Sibford stencilled on to the backs of their heads as part of a money-raising project.

Sibford School, near Banbury, wants 2m to fund a new arts block and swimming pool.

The green hair event is organised by the di Cuffa family who run the Andrea salon in Chipping Norton, and the stencils will be supplied by Adorn of Banbury.

Headteacher Sue Freestone said: "It's not often we encourage our children to break the rules, but in this case we know they want to support the school, and this is a fun way for them to do it."

Parents need not worry. The dye used is washable and easily removed.

On Sunday, both salons will be offering haircuts and other beauty treatments with proceeds going to the fund.
