OLAPLEX No.0. is a companion to OLAPLEX No.3 for an intensive at-home reparative treatment. No.0 can certainly works on its own and will provide repair; however, the product is intended to work as a two-part process.
HOW TO USE
Apply No.0 to DRY hair, fully saturating each section. Let process for 10 minutes. DO NOT RINSE. Apply No.3 Hair Perfector (sold separately) over hair with No.0 applied to it, combing through as needed. Let process for a minimum of 10 minutes. Rinse, shampoo & condition. For best results, use No.4 Shampoo & No.5 Conditioner.
To use No.0, simply: Apply the No.0 to clean dry hair. Comb the product through to ensure saturation. Wait 10 minutes, then apply OLAPLEX No.3 Hair Perfector directly on top of No.0. Comb again to saturate thoroughly, then let the treatment sit for another ten minutes. This treatment is a minimum of 20 minutes, though, just like the No.3 on its own, more significant results occur when keeping it on longer! Once completed, rinse, shampoo, and condition. We recommend the OLAPLEX No. 4 Shampoo and OLAPLEX No.5 Conditioner.
