Does zinc prevent gray hair?

Zinc doesn't prevent gray hair caused by aging or genetics, but maintaining adequate zinc levels, alongside copper and other nutrients (like B vitamins), can help prevent or slow premature graying by supporting melanin production, especially if you have a deficiency.

What triggers your body to make more melanin?

What hormone produces melanin?

The primary hormone that stimulates melanin production is Melanocyte-Stimulating Hormone (MSH), specifically alpha-MSH (α-MSH), which tells skin cells (melanocytes) to make the pigment melanin, leading to skin darkening (tanning) and protection from UV rays. MSH is released by the pituitary gland and other cells, often triggered by sun exposure, and it increases the activity of enzymes like tyrosinase, crucial for melanin synthesis.
