Wet your hair.
Apply a walnut-sized amount of shampoo to your hand and distribute it throughout your hair.
Add a little water and massage gently. Focus on some areas by pressing a little harder with your fingertips on each side of the head, on the top, and down to the nape. This type of massage promotes circulation.
Rinse and reapply a drop of shampoo to wash your hair thoroughly for the second time.
Rinse again with plenty of water: first with warm water and then with lukewarm water. Finish with a stream of cold water to close the cuticle and add shine.
