Suitable for oily scalps, the Biolage Scalp Sync Clarifying Shampoo delivers a gentle but effective cleanse that removes product build-up and daily debris. Enriched with a fermented tea blend and glycolic acid, the formula protects against excess sebum to keep the hair feeling fresh for up to 48 hours. Its light lather helps to rinse away impurities from the scalp without stripping away essential moisture, leaving the hair soft, smooth and shiny once dried.
