You know about Movember but have you heard of Februhairy? Sylvia Tracey is just one of the women who are taking on a hair-related challenge for the campaign.
As part of Februhairy's 'Support Better Breast Health' month, Tracey has stopped shaving under her armpits. And just in case it wasn't visible enough, she's also dyed her underarm hair pink.
Why? Tracey, a nurse, doesn't believe in using deodorants because of the chemicals found in many antiperspirant sprays and roll ons. Instead, Tracey relies on her underarm hair to trap bacteria.
Take a look below to hear from Tracey herself and see what happened after she stopped shaving for a few months...
