This suits anyone who uses a lot of styling product, lives with hard water, or wants a periodic reset for buildup without switching to a harsh, sulfate-heavy clarifying shampoo. Because the current formula is positioned as gentle enough for regular use, it also works for people who want a deep-cleansing shampoo they can rotate in more than once a month.

It's a consumer, at-home shampoo suitable across hair types and is described by KMS as gentle enough for color-treated hair since the current version is sulfate-free -- a real point of difference from most clarifying shampoos, which tend to fade color faster.

The differentiator versus a typical drugstore clarifying shampoo is that this one is designed to be used regularly rather than as an occasional deep-strip treatment, while still targeting the same hard-water and product buildup that dulls hair and disrupts scalp balance over time.

Wet hair thoroughly, apply the shampoo, and work it into a lather across the scalp and lengths, then rinse well. Repeat if hair or scalp still feels like it needs a second cleanse, and follow with a KMS Head Remedy conditioner or treatment.

• Wet hair thoroughly
• Apply shampoo and lather into scalp and lengths
• Rinse well
• Repeat if needed
• Follow with conditioner

Pros

• Positioned as gentle enough for regular/frequent use, unlike many clarifying shampoos that warn against frequent use
• Current formula is sulfate-free per KMS, which is milder on color-treated hair than most clarifying shampoos
• Formulated to balance scalp pH while removing buildup, rather than just stripping the hair
• Vegan formulation

Cons

• As a deep-cleanse/clarifying shampoo, it isn't a leave-you-conditioned formula on its own and is meant to be followed by a conditioner
• Sulfate-free clarifying shampoos typically lather and 'feel' less than sulfate versions, which some users read as weaker cleansing even when buildup removal is comparable
• Conflicting ingredient lists were found online for this product (see contradiction note), so the exact current formula on shelf may differ from what's documented on some retailer sites
