Wet the hair.

Apply a walnut-sized amount of shampoo to your hand and distribute it through the 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 then moving down to the nape.

These types of massages stimulate circulation.

Rinse and apply another drop of shampoo to wash the hair thoroughly for a 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.
