OLAPLEX Bond Building Technology™ uses a single molecule (Bis-Aminopropyl Diglycol Dimaleate) to drastically and instantly improve hair strength. This system is able to repair disulfide bonds from the inside out, contributing, therefore to healthier, stronger and more resilient strands.

How to use

Apply OLAPLEX Blonde Enhancer Toning Shampoo Nº4P 250ml to wet hair during your shower or bath, working the formula until it lathers. Then, let it act for one to three minutes. For more intense results, let the composition sit for up to five minutes. Rinse thoroughly. Use this product once to twice a week or often as needed to neutralize brassiness.
