We went throught the "do it yourself" haircut. DD was 3 1/2- she had a pair of safety scissors and chopped off about half of her beautiful, waist length Shirley Temple-esque corkscrew curls while I was making dinner. I saw her, screamed (and, I'll admit, cried a little), and whisked her off to the hair salon to fix it. She ended up with a Buster Brown ultra short bob (with bangs cut all the way down to her scalp

). In a few months, when the bangs had grown out, it ended up looking adorable.
After a very stern talking-to, DD learned that only hairdressers cut hair!!
