Red < Blonde < Dark haired < darker Hair
FYI this is also the order in which people are more resistant to the sun and other radiation, and generally have better immune systems. I have to mind where my DNA goes in evolution you know.
Also its a confirmation of Freud's words for me to feel this way, every woman in my family has dark hair.
Dark haired women look better without makeup or when she is tired and have more expression, and generally come across as being more intelligent to me.
they also age better.
