OLAPLEX Hydration Heroes Set is the brand's own boxed set of two: Nº·4 Bond Maintenance® Shampoo 100 ml and Rich Hydration Mask 200 ml. The front of the carton prints FULL SIZE on the mask jar. One side prints a two-step routine, quoted under How to use: the shampoo, then the mask, which the carton says to use in place of conditioner. Both are also sold on their own: the shampoo in 250 ml and the mask in 200 ml.

What is in the box

• Nº·4 Bond Maintenance® Shampoo: the first step, the wash. The printed step ends by squeezing the excess water from the hair before the mask.
• Rich Hydration Mask: the second step, applied after shampooing and used, in the carton's words, in place of conditioner.

Where it fits in the OLAPLEX range

The set sits on the OLAPLEX brand page next to the two singles it is made of. The shampoo is listed on its own under Shampoos & Conditioners, in 250 ml. The set's 100 ml bottle has no single listing of its own. The mask is listed under Repair Treatments & Serums in the same 200 ml jar as in the box, and also in 370 ml.
