They raised over $10,000 for the Pathstone Foundation and they're going to chop off more than 30 inches of hair to celebrate.
Three Grade 10 students from Blessed Trinity Catholic Secondary in Grimsby banded together to raise the money through the Mane Event campaign over the past six weeks.
It all ends this Monday with a big hair chop event at Malia Hair Salon in St. Catharines.
It will be live streamed on the campaigns Instagram page (@Mane7.18) starting at 3:00 p.m.
