Olaplex No.0 is a salon-inspired pre-treatment formulated to prep hair for optimal conditioning care. This lightweight, targeted primer works best when paired with No.3 Hair Perfector™, helping support hair’s strength and appearance. Ideal for at-home use, it is designed to be applied before your regular No.3 treatment to boost performance and enhance the feel and manageability of damaged-looking hair.

Key Features:

• Pre-treatment that primes hair before using No.3

• Designed to support visibly healthier-looking strands

• Lightweight, easy-to-apply liquid formula

• Ideal for dry, processed, or stressed hair

• Best when used with No.3 Hair Perfector™

How to Use:
Apply No.0 slowly to dry hair, distributing evenly from root to tip. Leave on for 10 minutes, then apply No.3 Hair Perfector directly on top of No.0 without rinsing. Comb through and leave on for another 10 minutes. Rinse, shampoo, and condition.
