Once you have these two simple things, actually getting the hair dye off your skin couldn't be easier.
To get hair dye off your skin, pour the olive oil onto the bumpy side of the exfoliating round. You want enough oil to coat the cotton, but not SO much that it's completely sodden.
Gently but firmly rub the cotton round in small circles anywhere on your skin where you have hair dye marks. You may need to use several rounds to remove all the color, depending on the type of dye used, but you'll see it coming away on the rounds REALLY quickly.
Oh, and an important note: If you have sensitive skin or certain skin conditions like eczema, talk to your doctor before coloring your hair OR using olive oil to remove stains.
Coloring your hair is one of the great joys of life. Now go forth and rock every hair color in the rainbow, secure in the knowledge that you can get ANY hair dye off your skin quickly, safely, and easily.
Your follicular creativity is safe, as long as you have olive oil — and some scrubby pads — nearby.
