Hydrogen peroxide can destroy the pigment melanin in hair, leading to premature graying.
Here are some other factors that can affect melanin production in hair:
- Sun damage: Excessive sun exposure can damage melanin production in hair, leading to color changes.
- Hair dyes: Certain chemicals in hair dyes, such as resorcinol and lawsone, can downregulate the production of melanin.
- Genetics: Variations in genes responsible for melanin production can influence hair color and the amount of melanin produced.
- Stress: Stress can deplete melanocyte stem cells, leading to a decrease in melanin production and graying hair.
It's important to note that melanin is not "killed" in the sense of being destroyed. Instead, its production is reduced or disrupted.
