Pre-shampoo bond repair treatment. Reduces snap-off breakage after 4 weekly sessions. Apply to wet hair 10 minutes before shampooing. 100ml. $30.
Best for bleach damage — the bond-repair chemistry targets snap-off breakage, and users report the difference within about a month.
Olaplex No.3 is not a conditioner — and understanding that distinction is the key to using it correctly. Applied pre-shampoo to wet hair for 10 minutes, the bonding chemistry targets snap-off breakage; owners typically report fewer strands coming away during detangling after about four weekly sessions. The formula feels thin and watery, which surprises first-time users expecting a creamy mask texture. It does not make hair soft — that is a conditioner's job. On a per-ml basis at $30/100ml it is the most expensive here.
Pros
- Owners report less breakage after four weekly sessions
- Bond repair targets the structural cause of brittleness
- Works on bleach, heat, and chemical damage
Cons
- Expensive per ml at $30/100ml — short lifespan at weekly use
