OGX Bond Protein Repair Sealing Serum is a lightweight, leave-in treatment that revitalizes dry, damaged hair without weighing it down. It uses a Bond Protein Complex to deliver targeted repair where hair needs it most, helping each strand look healthier, more pliable, and stronger. Powered by a two‑pronged repair system, this serum rebuilds bonds inside the cortex while smoothing the cuticle’s surface. The gel-like formula includes sealing agents that keep hair light, making it ideal for fine strands. It can be used as an overnight leave-in, with no rinse required, so you wake up to softer, stronger hair.
