Do men use conditioner?

On the phone to my friend just now, explained that I was annoyed at forgetting to buy conditioner when at the supermarket earlier. She laughed and exclaimed

“why do you need conditioner???”

Me : “Huh? Everyone uses shampoo and conditioner?”

“No they don’t!”

Me : “Well I was brought up being told to use it”

“no man I know uses conditioner!”

So.. do they?
