Key Ingredients & Benefits

  • Patented Bis – Aminopropyl Diglycol Dimaleate – helps protect and restore damaged hair by repairing disulphide bonds broken during chemical processing. Bleach, peroxide, perms and chemical straighteners damage hair at a molecular level, leaving hair more fragile and susceptible to breaking. Bis – Aminopropyl Diglycol Dimaleate is a truly innovative ingredient with protective, nourishing and restructuring action for rejuvenating hair. Only available in Olaplex products.
  • Mild Sulfate-free surfactants derived from coconuts – Non-drying, gentle on colour treated and chemically processed hair and scalp. Leaves hair feeling clean and bouncy.
  • Glycerin – Offers excellent moisture balance and brings natural hydration to thirsty, dry hair.
  • Acetic Acid – A great scalp clarifier to prevent flakiness from forming. Brings out hair’s natural shine.
  • Panthenol – Penetrates the hair shaft to help it feel thicker and increase the strength of hair by giving it elasticity and improved resistance to breakage.
