Red hair is very rare. It occurs in 1-2% of people
Oh wow! I didn't know that, is that why red heads are sought after because they are exotic out of the population?
That's likely! People who have two copies of a recessive chromosome commonly have red hair.
I see! Are there other genetics rarities that interesting statistically?
When people have darker natural hair they have more hair follicles on their scalp.
Oh I did not know the either! I also that the sought after "dimples" people faces are actually a genetic disorder, but society has made the dimple a sought after facial feature!
Dimple
A dimple (also known as a gelasin) is a small natural indentation in the flesh on a part of the human body, most notably in the cheek or on the chin. 
Characteristics.
Cheek dimples when present, show up when a person makes a facial expression, such as smiling, whereas a chin dimple is a small line on the chin that stays on the chin without making any specific facial expressions. Dimples may appear and disappear over an extended period; a baby born with dimples in their

In science and nature Hair color.
Red hair occurs naturally on approximately 1–2% of the human population. It occurs more frequently (2–6%) in people of northern or western European ancestry, and less frequently in other populations. Red hair appears in people with two copies of a recessive gene on chromosome 16 which causes a mutation in the MC1R protein.
Red hair varies from a deep burgundy through burnt orange to bright copper. It is characterized by high levels of the reddish pigment pheomelanin (
