Miriam Quevedo Extreme Purifying Charcoal Shampoo is a restructuring shampoo for oily hair. When hair appears weighed down, dull, or tends to get dirty easily, it's time for a targeted purifying action. With its formula based on activated charcoal, Extreme Purifying Charcoal Shampoo regulates sebum production, frees the scalp from impurities and build-up, and improves the absorption of valuable ingredients such as antioxidant vitamins, repairing peptides, gentle organic sulfur, and natural plant extracts. With regular use, it also helps restore damaged keratin and retain moisture, leaving hair immediately lighter, shinier, and healthier. Extreme Purifying Charcoal Shampoo is also gentle on colored or keratin-treated hair, and is perfect for chi seeking deep cleansing without sacrificing care.
