Take a walnut-sized amount of shampoo in your hand and dilute with a little water in your hand or directly on your scalp using the shower.

Massage the scalp generously for 1 minute, giving the shampoo time to work properly. Leave on for 1 minute and rinse with water.

Use the rinse water for the lengths and ends. If you have a lot of hair, long or curly, a second shampoo may be necessary.
