Hair products, hard water and mineral deposits, chlorine and environmental impurities can all leave scalp buildup over time—which can cause dull, greasy or limp hair. What clarifying shampoos do is work to remove the buildup that causes dull, lifeless hair. Moroccanoil® Clarifying Shampoo is a deep-cleansing formula that removes everyday buildup, restoring hair to a weightless, healthy balance. Rich in argan and avocado oils, keratin, lavender, chamomile and jojoba extracts, this clarifying shampoo nourishes your hair while gently cleansing impurities away. Color-safe. Sulfate-free, phosphate-free and paraben-free.
