✦ The Medieval and Renaissance Eras saw women using apples, alum, tea barks, and walnut shells to change their hair color. Women would also use a mixture of sulfur, lead, and quicklime cooked together, to give a brown color to their hair. Another option was, they would pile roots and leaves on top of their head, tie all this together with a sinew, and leave it on their head to rot for 2 days.
