HOT-HEADED: Ed Sheeran and Prince Harry (Getty Images)
Sperm donor collection companies are calling on ginger-haired men to step up to the plate to stop redheads from dying out.
Only 2 percent of donors are redheads and handsome flame-haired guys like music sensation Ed Sheeran and Prince Harry have seen demand skyrocket.
It's a stark change from 2011 when one of the world's biggest sperm banks Cyros International stopped accepting donations from redheads due to dwindling interest.
Co-ParentMatch.com is one of the companies behind the push and is using the hashtag #SaveGingers to raise awareness of their pro-ginger campaign.
