OLAPLEX No.0 Primes hair to absorb nourishment for maximum repair.

A professional-inspired at-home treatment that primes hair for deeper repair with the highest dose of patented OLAPLEX technology in any take-home product.



It rebuilds hair bonds, strengthens and protects hair integrity. Use as the first step in a two-part system with No.3 Hair Perfector followed by N°4 Shampoo and N°5 Conditioner.


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.



How to use

  1. Apply No.0 to DRY hair, fully saturating each section.
  2. Let process for 10 minutes.
  3. DO NOT RINSE. Apply No.3 Hair Perfector (sold separately) over hair with No.0 applied to it, combing through as needed.
  4. Let process for a minimum of 10 minutes. Rinse, shampoo & condition.
  5. For best results, use No.4 Shampoo & No.5 Conditioner.
  6. Use the two-part system once a week or two to three times a week for damaged hair.
