Blonde hair has so many different rangers from light blond to dark blone.
Yes, i am light blonde and so is our president
I go back and forth with the sun it seems, from more sandy blond to strawberry blond.
What do you think determines the color of our hair?
Apparently there are two types of melanin, eumelanin (more of this means darker) and pheomelanin.
That is so good to know. Do you mean the same melanin in our skin is present in the hair?
Yep, and the pheomelanin can give us red hair if it's in the highest concentration.
I guess that is what i have. 
It's pretty unique.  Only 1-2% of the human population have red hair!
