Our take on the K18 DAMAGE SHIELD pH Protective Shampoo 8.5 oz & Conditioner 8.5 oz Combo Pack

This is K18's Damage Shield pair: a pH-optimized protective shampoo and a matching conditioner, both 8.5 oz. The shampoo leans on K18Peptide, the brand's bond-repairing peptide, and is marketed as color-safe and gentle enough not to strip natural oils. It suits people with chemically treated, heat-styled or generally fragile hair who want a maintenance wash between K18 treatments. Against ordinary sulfate shampoos it is milder and aimed at repair, but it is not a deep-cleansing or volume shampoo, and the conditioner is a light everyday partner rather than a mask.

Questions and answers

Is this the same as the K18 leave-in mask?
No. The leave-in mask is a treatment you apply and don't rinse out. This set is a rinse-out shampoo and conditioner built around the same K18Peptide.
Can I use it on color-treated hair?
Yes. The shampoo is formulated as color-safe and pH-optimized, so it cleanses without stripping color as aggressively as stronger sulfate shampoos.
Do I still need a separate deep conditioner?
The conditioner is light. If your hair is coarse, very dry or heavily bleached, you may want a richer mask once a week alongside it.
How often should I wash with it?
It is gentle enough for frequent washing. People with oily scalps or heavy product use may want a clarifying wash occasionally.
What's in the box?
One 8.5 oz bottle of Damage Shield pH Protective Shampoo and one 8.5 oz bottle of the matching conditioner.
