Where does the colour in our hair come from?
Within the interior of each of your hair fibres is the cortex. Your hair’s cortex contains many packets of pigment. There are two known types of pigment or melanin in human hair.
Dark hair has an abundance of eumelanin, whereas blond/red hair has a majority of pheomelanin.
The full beautiful range of colours seen arises due to differences in these colour molecules' relative abundances and their total concentrations.
Other factors play important roles in hair colour and hair colour perception (using the human eye), so for a deeper dive into hair colour, check out our other colour guide.
