The most common reason for an orange goatee is due to a difference in pigmentation, specifically related to pheomelanin.
Here's a breakdown:
-
Melanin and Hair Color: Hair color is determined by melanin, a pigment. There are two main types:
- Eumelanin: Responsible for brown and black hair.
- Pheomelanin: Responsible for red and blonde hair.
-
Varied Pigmentation: You might have a higher concentration of pheomelanin in your goatee hair compared to the hair on your head or other facial hair. This difference in melanin levels causes the orange or reddish hue.
-
Genetics: Your genetic makeup dictates the amount and type of melanin your body produces in different areas. This explains why some people have patches of different colored hair.
-
Sun Exposure: While not the primary reason, sun exposure can lighten hair, including the goatee. If you naturally have some pheomelanin in your goatee, the sun might bleach the eumelanin, making the reddish/orange tones more prominent.
