How to use

First up, give your hair a pre-wash with your usual shampoo to remove product build up and open your hair up. Then, lather a walnut or so of this shampoo through your hair and leave it to sit for 3-5 minutes. Rinse, and follow with either conditioner or a hair mask. Use weekly or whenever you feel like your hair needs brightening. Be sure to work quickly and rinse your hands - this is a strong and punchy purple shampoo.
