Formulated with patented OLAPLEX bond-building chemistry.
The Olaplex no.4 shampoo restores, repairs and hydrates to add incredible shine and manageability every time you shampoo using the OLAPLEX 3-4-5 system (use Olaplex shampoo with Olaplex No. 3 Hair Perfector and Olaplex No.5 Bond Maintenance Conditioner for the best results).
- Formulated for daily or every wash use. Concentrate on roots. Use every time you shampoo or after rinsing Olaplex No. 3 Hair Perfector from your hair. Emulsify a small amount in hands to activate and jump-start the lather before applying to wet hair. Massage into scalp and hair and rinse well.
- Follow with Olaplex No. 5 Bond Maintenance Conditioner.
