Nº.0 Intensive Bond Building Treatment
Pre-shampoo bond primer — the starting gun for a full Olaplex treatment
A pre-shampoo priming treatment applied to dry hair before No.3 Hair Perfector. It prepares hair to absorb the subsequent treatment more effectively, extending its repair benefits. Applied from roots to ends, left for 10 minutes, then topped with No.3 before rinsing both together. The most impactful way to use Olaplex at home — but the two-step commitment does add time to wash day. Best for colour-treated, bleached, or significantly damaged curls.
