While most people may begin with their face, you should cleanse your hair first and foremost. A thorough rinse will loosen up any dirt and oil prior to shampooing and then you can squeeze a dime-sized amount of shampoo into your locks, working it into a rich lather. Don’t forget the back of your neck, as this often-neglected spot is where most of your hair’s natural oils collect.
Once you’ve rinsed out all the product, squeeze (don't wring!) your hair to remove any excess water, and finish with conditioner on the lower half of your locks.
