We generally recommend replacing your regular shampoo with a purifying shampoo about every 8 washes or once a month.
Step 1 : Apply the purifying shampoo to wet hair and gently massage into hair and scalp. Use a scalp brush to maximize the cleansing effect.
Step 2 : Leave on for 1 minute or leave the shampoo on longer if you need a more intense cleanse.
Step 3 : Rinse and apply your favorite hair mask and conditioner.
