Collistar's Pure Actives Vitamin C Shampoo is a brightening, energising daily shampoo in a 250ml bottle, built around vitamin C as its hero ingredient. The mild cleansing base washes gently while supporting the look of healthier, shinier hair. It is a practical everyday option for hair that has been dulled by environmental stress, hard water or heat styling. The formula is vegan, made in Italy, and works well alongside the matching Pure Active Vitamin C Conditioner.
