I have highly variable hair. Nice sometimes - bad others. My hair often frizzes on contact with moisture.
Normally it doesn't matter too much, but today I was helping to run an event. The weather in London was damp and drizzly.
At lunch I said to a colleague "I'm having a bad hair day and it's only getting worse."
Now, guys and gals, everyone knows the correct response is: "It's fine. It looks nice. Don't be silly."
I got: "It's the humidity," and a sympathetic smile.
