OLAPLEX® No.4P BLONDE ENHANCER™ TONING SHAMPOO is a purple shampoo that strengthens, softens, and neutralizes. Diminishes unwanted yellow tones in blonde hair while giving it a cool, bright tone. A highly concentrated and sulfate-free formula that makes it possible to tailor your shade. The longer you leave the product on, the more intense the results.

How to use:

Apply to damp hair and massage into your hair. Leave on for 1-3 minutes, then rinse. For a more intense tone, leave on for up to 5 minutes.

Tip: If you have a lot of product residue in your hair, start by cleansing your hair with No.4 BOND.
