What's the length of too short a haircut? About 7-10 days, I reckon. I have a lovely hairdresser, but he does like to chat.
Chat, chat, snip, snip, what do you think, snip, snip, did you read about, snip, snip, did you see, snip, snip, did you hear about, snip, snip.
And before you know it, your hair is shorter than you'd planned on having.
There are two options:
1) blast hair from underneath with a hair dryer and slap on styling product.
2) wear a hat.
