Olaplex No.3 Hair Perfector

Olaplex No.3 is the at-home step of the bond system, and its name misleads people — it is a pre-shampoo treatment, not a conditioner or a mask. You work it into damp, towel-dried hair, leave it at least ten minutes, then shampoo and condition afterward. That sequence matters for Asian hair taken to ash or platinum, where the bleaching that makes those tones possible is exactly what breaks the bonds holding the strand together; No.3 relinks some of them, so hair snaps less and holds its shape better. It suits bleached, permed, or chemically straightened hair, about weekly. It rebuilds bonds rather than moisturizing — used alone it can feel rough, so always follow with a conditioner or mask.
