Known as the “invention,” the Bis-Aminopropyl Diglycol Dimaleate ingredient allowed professionals to reach new heights in color & care. Hair wasn't just healthier; it took on a completely different quality — blondes were brighter, brunettes more radiant, and redheads more vibrant.
WHAT ARE HAIR BONDS?
Hair is made up of the fibrous protein, keratin, and held together by bonds. Hydrogen and salt bonds are physical bonds and are easily reformed by changes in pH, water and/or heat. Disulfide bonds are chemical covalent bonds. These bonds cannot be broken by water. Millions of disulfide bonds give hair its structure, strength, and stability.
When these disulfide bonds are broken, hair is damaged and can appear dry, frizzy, and brittle.
