Our Take
A clarifying shampoo designed to remove product buildup, hard water deposits, and environmental residue. Contains sulphates, making it the most powerful cleanser in the Olaplex range — and the only one that falls outside CGM guidelines entirely. Use every 4–6 washes as a reset, not as your regular shampoo. Particularly useful if you're using silicone-containing Olaplex products (No.3, No.5, No.6) and need a periodic deep clean to prevent buildup.
