Olaplex is a three-step hair repair system that is especially suited to those who find that hair coloring treatments are incredibly damaging. The products, named No. 1, No. 2 and No. 3 are designed to prevent breakage during coloring and repair broken bonds that may have occurred in the process.
The first product in the system is blended into bleach, lightener or hair color and applied to the hair. This first step is essential for reversing the damage that tends to happen from chemical treatments or the use of heat on hair. While No. 2 is used in-salon by professionals, No. 3 is a slightly less intense version that is safe for use by the average consumer at home.
Olaplex is not to be confused for a conditioner—this system is a reparative one that rebuilds and reconnects broken bonds.
