I have brown hair but my daughter is a red head. Must be somewhere back in our family line because only 1-2% of people have it naturally.
That's cool, I'm a brunette, and my brother is a red head. This is super rare then.
That is amazing that you have a red head in your family too! ha ha. I was reading about it and its a recessive allele on chromosome 16 that changes a protein that causes red hair. So, genetics! Does your brother like his red hair?
I think he does, He got the irish side, I got the Cherokee side.
Does he have deep burgundy hair or more a bright copper?  My daughter's is more a vibrant strawberry blonde. There are so many different hues.
