Since an electron-donating substituent will usually also increase the π electron density all over the aromatic ring, such rings react with electrophiles faster than benzene; sometimes so much so that milder conditions have to be used. Thus a hydroxybenzene is as reactive to electrophiles as an alkene, but still giving substitution reactions rather than addition.
