Experience an intensive repair process that rebuilds and strengthens each strand from within.</p><p>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.<br>When these disulfide bonds are broken, hair is damaged and can appear dry, frizzy, and brittle.</p><p><strong>SIGNS OF DAMAGE&nbsp;</strong></p><ul><li>Split ends</li><li>frizz</li><li>Dryness</li><li>Dullness</li><li>Breakage</li></ul><p><strong>CAUSES OF DAMAGE</strong></p><ul><li>Hot Tools</li><li>Environment</li><li>Chemicals&nbsp;</li><li>Styling</li><li>Aging/Life Style</li></ul><h3>HOW OLAPLEX HEALS</h3><p>Our patented OLAPLEX bond-building technology penetrates on a molecular level in all hair types.</p><p><strong>Bis-Aminopropyl Diglycol Dimaleate</strong> - a single molecule, works in a unique way to quickly and effectively repair broken bonds and restore healthy hair.</p><p>This active ingredient is included in every one of our products, imparting them with reparative and protective characteristics.</p>
