* Eumelanin: This pigment gives hair its brown and black colors. The more eumelanin you have, the darker your hair will be.
* Pheomelanin: This pigment gives hair its red and blonde colors. The more pheomelanin you have, the redder or blonder your hair will be.
Here's how it works:
* Melanin production: Melanin is produced by cells called melanocytes, which are located in the hair follicle.
* Genetic influence: The amount and type of melanin produced are determined by your genes.
* Hair color variation: The combination of eumelanin and pheomelanin determines the final color of your hair.
* Gray hair: As we age, our melanocytes produce less melanin, leading to gray or white hair.
Other factors that can influence hair color:
* Sunlight: Exposure to sunlight can lighten hair color over time.
* Chemicals: Hair dyes and bleaches can change the color of hair.
* Health conditions: Some medical conditions can affect hair color, such as vitiligo (which causes patches of white hair).
* Hormones: Hormonal changes can also affect hair color, such as during pregnancy or menopause.
