The OGX Anti-Breakage+ Keratin Oil collection strengthens and smooths damaged, brittle hair. Infused with keratin oil, the shampoo cleanses, tames frizz, hydrates, and reinforces weak strands. Keratin molecules bond to rough hair fibers, sealing the cuticle and reducing split ends, leaving hair stronger, smoother, and shinier. Perfect for overtaxed hair from heat or chemical damage.
