Can grey hair really be reversed? Here's what one scientific study says

Can stress cause your hair to grey — and can it reverse? Anthony Morgan, co-host of The Nature of Things, takes a closer look at new research showing how lifestyle choices may influence hair colour. In Hairy Tales, a documentary from The Nature of Things, hosts Sarika Cullis-Suzuki and Morgan explore the fascinating science of hair. Along the way, they reveal their own hair dilemmas and untangle surprising new research, which suggests the science of hair is anything but cut and dried.
