Soften and smooth your hair with Paul Mitchell's Smoothing Litre Duo, comprising a shampoo and conditioner. Both products come in supersize one-litre bottles, with Paul Mitchell pumps for easy use. The shampoo is designed to deep cleanse your hair, while the conditioner works to nourish your strands. Use the shampoo to transform your hair, reducing frizz and untangling knots. Your hair feels sleeker and easier to style after shampooing. The conditioner contains thermal protectors that prevent cuticle cracks and strengthen the hair so you can style it with more reassurance. Your hair becomes silky smooth after use of the conditioner, so you can wet style it or wet comb it afterwards.
