Considering the reactions, I think the best option (if lengthy) would be to have had multiple rounds of voting. First having almost all the hair styles save for duplicates and unfeasible/rule-breaker types and the like, group them by generalized styles... and then vote for a favorite of those. Then have a second vote with all the winners to decide on the actual winning hairstyle.
Would've been a lot of hair to go through and a lot more time spent, though.
