Miriam Quevedo Extreme Purifying Charcoal Shampoo is a restructuring shampoo for oily hair. When hair appears weighed down, dull, or prone to dirt, it's time for a targeted purifying treatment. With its activated charcoal formula, Extreme Purifying Charcoal Shampoo regulates sebum production, frees the scalp from impurities and buildup, 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 instantly lighter, shinier, and healthier. Extreme Purifying Charcoal Shampoo is gentle even on color-treated or keratin-treated hair, and is perfect for those seeking a deep cleanse without sacrificing care.
