Is there clinical or laboratory data behind The Shampoo?Updated 2 months ago

Yes — at the cosmetic-active level. The actives in The Shampoo are supported by supplier cosmetic-active studies, including:

• CutiBiome CLR™ — a +60% improvement in dandruff scores versus a piroctone olamine 0.1% comparator after 4 weeks, and an 81% reduction in scalp oiliness versus the same comparator.
• Patchoul’Up™ — normalises sebum production on a dry, dysbiotic scalp, +34% versus placebo after 4 weeks (rinse-off).
• Piroctone olamine — clinically validated antifungal efficacy with superior tolerability versus zinc pyrithione, preserving the beneficial scalp microbiome.

These are active-level results. Full finished-product clinical testing of The Shampoo is underway, with results expected later in 2026; we’ll update this page with those findings once they complete peer review.
