When I was younger, I had dark brown hair, but very red highlights. The red was most noticeable when the sun is at a lower angle in the sky. My eyebrows are black. My mustache was auburn with deep red highlights. I had a few stray deep red hairs in my beard, but mostly it was black and dark brown with red highlights. My body hair is entirely dark brown with golden red hghlights. Is this pattern a form of being a redhead? Does it suggest the genetic mutation for red hair?

Answer

Mutations in the MC1R gene may occur with any hair color, and the red color may be harder to discern for people who have black or dark brown hair. It is quite likely you have the genetic mutation for red hair, which is harder to observe as the darker hair color masks the phenotype.
