Grey Hair

What is Grey Hair ?

Our hair colour is determined by the quantity, distribution and types of melanin within each hair.

There are 2 types of melanin and our hair colour is based on the combination of these two colours:

  1. Eumelanin: - Dark red, brown to black.
    - Asian people have more Eumelanin than Phaeomelanin.
  2. Phaeomelanin: - Light yellow to red.
    - European people have more Phaeomelanin than Eumelanin.
  • Grey hair occurs when bulbar melanogenetic cells produce less melanin.
  • Some people do not experience total white hair but grey hair with light brown.
  • This is because our bulbar melanogenetic cells still produce melanin but at insufficient level.
