The dropper button is to tint your skin, or lashes, or brows, you can undo it by clicking on clear. You can go to the last, or next to last button and click reset and it will turn your head white again. You can use the little buttons at the bottom to keep preset lashes, etc from designers you like. Just hold button down for a second, or two then int he box to the upper right click save. Did that help at all? I'm wearing hdpro soft majer head in my picture.
