How do people get their hair colour?

Banner

This week we have a TPL Kids website visitor who may have been looking at their friends’ hair and wondered… how do people get their hair colour?

 

For this wonder, we found an answer from the US National Library of Medicine:

Hair color is determined by the amount of a pigment called melanin in hair. An abundance of one type of melanin, called eumelanin, gives people black or brown hair. An abundance of another pigment, called pheomelanin, gives people red hair. The type and amount of melanin in hair is determined by many genes, although little is known about most of them

 

So the next time you’re wondering why you have a certain colour hair, you can thank your genes for the colour.
