Lite Relief : Can Anybody help?

There must be many that waste their money visiting hairdressing shops. So maybe somebody out there can help me with a question that has bothered me for many years. OK I used to visit the hairdresser once when that was the only place to buy condoms without anybody else knowing. Nudge nudge wink wink you know what i mean. OK I admit it. But this is not my point.

Why do we never hear a hairdresser fart?
I am sure they cannot all be Queens !
