Right today I was in town, and I needed hairspray cuz I ran out this morning

So I goes into Tescos to buy the wee cheap 78p normal one, but it wasn't there! So I had to buy some other random one. Then later on it got really windy, so I sprayed some into my hair, but it wasn't sticking or anything :/ So I sprayed more and more but still no effect. I looked at the bottle and it was BODY SPRAY.
I feel so ashamed.
