- Allow the treatment to sit for a minimum of 10 minutes without rinsing.
- After the initial 10 minutes, layer on Nº.3 Hair Perfector directly over Nº.0 and leave both treatments on for an additional 10 minutes.
- Thoroughly rinse out the treatments before cleansing with Olaplex Nº.4 Bond Maintenance® Shampoo and Nº.5 Bond Maintenance® Conditioner for optimal results.
