How to Use a Clarifying Shampoo

There are lots of reasons why hair can look sad and lifeless: too much heat styling, chemical treatment overdose, even hard water can make your strands go limp. Another sneaky culprit that can keep your hair from attaining maximum shine-factor?

Luckily, there is a solution. All you need is a good clarifying shampoo and the know-how to use it. Find out how on Harper's Bazaar.
