Looking at the OH group alone, oxygen gets -1 oxidation state, H gets +1 oxidation state. +1 -1 = 0 (since it's not an ion it adds up to zero). But each OH group has a spare space on each oxygen to grab another electron so each oxygen in each OH group can get to -2 oxidation state by grabbing another. Rules of assigning oxidation states.
