Product information

A colour-safe, pH-optimized shampoo with K18PEPTIDE™ to effectively cleanse while maintaining hair health for hair that feels strong, smooth, and healthy.

An optimized pH shampoo (4.5-5.5) helps prevent excess swelling of the hair cuticle to help reduce frizz, preserve color, and maintain health and shine—especially important for damaged hair. An optimized pH also helps preserve the scalp microbiome and is gentle enough to use every time you cleanse.
