Sandy, you have two options to find out what the Bible says about redheads, one quick and one slower, but better.
You can go to Biblegateway. com and put in redheads, or just google "Redheads in the Bible" and see if anything comes up. I don't think it does, because people living in the Middle East all had dark hair which is dominant. There might have been a few women in Egypt using henna to make their hair appear red, but I doubt God cares what colour hair or skin anyone has.
The other, better option is to read the Bible from Genesis to Revelation. Because you are redhaired, you would probably notice any references to it. You would also learn the Bible and hopefully learn how to find things on your own.
The final thing is to be secure in your calling in Christ. If you know for sure you are a born again Christian, why should it matter what any internet site or commentors says? Be strong and courageous! I am sure there are quit a few Irish believers, for example, who would take strong issue with this comment.
God loves a faithful and obedient heart, even if the head is bald, or the hairs are gray.
"O God, from my youth you have taught me,
and I still proclaim your wondrous deeds.
18 So even to old age and gray hairs,
O God, do not forsake me,
until I proclaim your might to another generation,
your power to all those to come" Psalm 71:17-18
I found this verse in my early 50's when my hair started turning quite gray and it gave me great hope that I could still serve God.
