I heard that if you wash your hair in every day, your hair will fall out.

For example:

This magazine article, Hair loss dos and don'ts for men who are going bald:

DON'T WASH YOUR HAIR EVERY DAY

Most men don't need to wash their hair every day.

Too much shampoo or conditioner on a daily basis breaks down the natural structure of your hair.

Is it true that shampoos harm the hair or the head skin?
