Men's Life Today: Expert Q+A

My girlfriend says I should be using hair conditioner, but I have short hair and have never used it before. Is she right, and if so, why?

The only way she’d be right is if your hair is really coarse or dry. Otherwise, there’s no need for it. Conditioner -- leave-in or regular -- simply weighs short hair down. Guys with longer hair can benefit from it, but you can just shampoo. If anything, to make her happy, switch to a moisturizing shampoo.
