Well, whatever she did with horns/hair, etc, was way in the past. By the time you have Regina ready to cast the original curse, Maleficent is seen with just a tiara (that is only vaguely reminiscent of her horned helm), and lots of flowing blonde hair.

And I agree with Lady J, both regarding the Frozen arc, and with the truly coincidental appearance of Maleficent on the heels of Angelina Jolie's portrayal. Maleficent was at least sketched out all the way back in season one, they had the right actress for the role, they just needed to wait for her schedule to clear.
