The Novafusion Cool Naturals Shampoo by De Lorenzo is perfect for coloured hair. This shampoo reduces brassy tones in brown hair, and adds a soft ash to white and grey hair. The UV inhibitors in this shampoo help to enhance your colour whilst providing protection against colour fade and reducing unwanted brassy tones of your colour. For best results, lather this shampoo into your damp hair for up to 5 minutes before rinsing thoroughly and follow up with colour care conditioner.
