• 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:
(a). Eumelanin: - Dark red, brown to black.
- Asian people have more Eumelanin than Phaeomelanin.
(b). 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.
| Causes of grey hair: |

(e).Nutrient insufficient such as protein, cooper,
