September 8, 2006: My husband has bright orangey red hair with thick tight curls. I have stick straight Auburn hair (although as a child it went from a light strawberry blonde to a flaming red orange, slowly darkening to my auburn colour). I've heard that 2 redheads can only have redheaded children. So far, seems true - although all are different. Our first has soft curls, bright orange. Our second has straight, auburn. Our third really straight, light strawberry blonde. If we have more will they be redheads too? Why the variations in shades? Is it true 2 redheads can only have redheads?
