_______________________________.

Reason -

First we'll see the word 'did', it's V2, so we'll change it to Were/Was. Then, we'll switch the subject and object. Since, Hair are plural, we'll use 'were' in the beginning of the sentence. After her hair, we'll add the verb, kept. Then, we'll use the word 'by' to join the sentence. Thus, our answer is

Were her hair kept long or short by her?
