Is your shampoo honest?

Paste a hair/scalp shampoo's full ingredient list or snap a photo. We score evidence-backed actives vs. concept ingredients (trace marketing) by their position on the label.

Ingredients are listed in descending order of concentration. So a 'hero' ingredient near the tail is effectively trace (<1%) — we use that position to detect overclaim.
※ For reference only, based on public ingredient data and regulator positions — not medical advice. Popular ingredients like beer yeast or black bean are also flagged as concept ingredients, no exceptions.
