Olaplex No.0 Intensive Bond Building Hair Treatment
Best for Repeated Lightening
The primer: a spray on first step the brand directs underneath No.3, for hair that needs the deepest version of the Olaplex routine.
Hair that has been lifted more than once is the primer's home ground: the brand directs No.0 under No.3 precisely for the deepest version of its routine, and repeated lightening is where owners report that pairing earning its extra step.
Suits
Heavily bleached, repeatedly coloured or otherwise seriously compromised hair, used as the brand directs: as the priming half of a two step routine with No.3 layered over it.
Skip if
You want one product, one step. No.0 is published as a primer for No.3 and is not positioned as a standalone treatment; on its own it is the wrong purchase, and No.3 alone covers milder damage.
