CORK, IRELAND - AUGUST 22: The Wellband family of redheads attend the Irish Redhead Convention which celebrates everything to do with red hair held in the village of Crosshaven on August 21, 2015 in Cork, Ireland. Some of the events include the coronation of the Redhead King and Queen, Carrot-tossing, ginger speed-dating, best red beard, best red dog, freckle counting and a redhead parade. The Convention began as a friendly joke between redheaded siblings Joleen and Denis Cronin and also serves as a fundraiser for the Irish Cancer Society raising awareness about skin cancer and melanoma. Red hair is the rarest of hair colours and accounts for just 0.6% of the global population. Ireland has the second highest per capita population of redheads at 10%, next only to Scotland at 13%. The United States is believed to have less than 2% of redheads.  (Photo by Clodagh Kilcoyne/Getty Images)
