The Art and skill of shampooing your hair:
Dry Run: Comb your hair with a wide tooth comb before wetting
Pre Soak: This is vital, as you will use less shampoo.
Apply and lathering: Pour shampoo on the palm of your hand, rub together then shampoo. massage your scalp with your fingertips for 30 seconds from front to back to avoid tangling.
Rinse: This should be done longer than you think, there is no point in finishing off with a cold rinse unless you enjoy it. One shampoo is all that is necessary when washing your hair daily.
