Olaplex 

WHAT’S A BOND?
Our hair contains millions of disulfide bonds.
These bonds give the hair its structure, strength and stability. When disulfide bonds are broken, it results in damage. 

OLAPLEX restores damaged and compromised hair by repairing from the inside out with our patented single ingredient, Bis-Aminopropyl Diglycol Dimaleate.

Once all the bonds are intact and in alignment, you have healthy, beautiful, shiny, touchable hair.
