Leaves hair and scalp clean without causing drynes

This is the best clarifying shampoo, especially if used before the K18 leave-in treatment. I’d used other high end clarifying shampoos before the K18 treatment and didn’t really have any complaints, but this clarifying shampoo really removed all product buildup, leaving my hair better ready to absorb the treatment. I’ve used it without following up with the leave-in treatment (used my regular leave-ins), and I can feel a difference in how clean my hair and scalp are without causing dryness.

Effective with mild scent

This is my favourite detox shampoo. I’ve repurchased it many times. It’s effective without being stripping to my fine wavy curly hair. I also love that the scent is so mild and not irritating to those sensitive to scents.
