by Olaplex
Updated November 10, 2026
Bis-Aminopropyl Diglycol Dimaleate primer strengthens damaged hair for fragile lengths; mixed payoff.
What the community says
This water-based bond-building primer uses Bis-Aminopropyl Diglycol Dimaleate before a second repair step, with a 10-minute wait on dry hair. It targets bleached or fragile lengths; fine hair may find the routine time-heavy, with reports of dryness and shedding.
