Can grey hair really turn back to its natural colour

Think greying hair is a one-way street? Not always.

Our hair colour depends on the health of melanocytes — pigment-producing cells that can ‘switch back on’ when oxidative stress drops and nutrient status improves.

Grey hair can signal deeper imbalances like zinc, copper, iron, or B12 deficiency, poor gut absorption, chronic stress, thyroid issues, or even autoimmune pigment loss (like vitiligo).

By correcting the root causes — from gut health to mineral status — you’re not just supporting your hair… you’re improving your whole-body resilience.
