@thebiohackingrn: Gray hair isn’t always just aging. Hair pigment depends on melanin production, which requires copper-dependent enzymes to function properly. Modern diets and mineral imbalances may reduce usable copper levels, while nutrient-dense ancestral foods like grass-fed beef liver naturally provide copper, retinol, and B vitamins that support normal hair pigmentation pathways from within. #grayhair #biohacking #copperdeficiency #ancestralnutrition #beefliverbenefits
