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 hair subjected to heat styling, color or chemical treatment, sometimes brushing & tugging or due to weather may lead to breakage of these disulfide bonds. When these disulfide bonds are broken, hair is damaged and can appear dry, frizzy, and brittle. Olaplex N°.9 Bond Protector Nourishing Hair Serum Neutralizes free radicals and protects against pollution for up to 48 hours.
