The Ingredient Court — trial by evidence, not hype
⚖ Now in session

Every ingredient list
deserves a fair trial.

Paste what's in your shampoo, conditioner, or styler. We'll cross-examine every ingredient and hand down a verdict on the product — no guessing, no gatekeeping jargon.

Put a Product on Trial ⚖ Browse the Docket
Guilty

Trash it.

The product carries at least one serious charge — a harsh, high-risk or build-up-prone ingredient at a concentration that matters. Our recommendation is to leave it out of your routine.

On Probation

Use with caution.

The product has something on its record, but nothing damning — minor charges, or serious ones only in trace amounts. Fine occasionally; worth watching if your scalp is sensitive or you use it often.

Innocent

Keep it.

Nothing in our case files against the product — no charges from any ingredient on it. Good to use.

Exhibit A

Put your product on trial

Copy the ingredient list straight off the label or the product page, paste it below, and let the court decide.

Separate ingredients with commas — same as they're printed on the bottle. We'll do the rest, typos and all.

How we reach a verdict

The product is what's on trial — not the ingredients. Each ingredient is evidence, and the product's verdict is decided by the evidence against it.

Every ingredient on our docket carries a category from our research file — labeled Harsh, No-Go, Medium, or Mild — plus three scores where we have them: Comedogenic (pore/follicle-clogging, 0–5), Irritation Risk (0–5), and General Safety (0–10). An ingredient counts as evidence against a product if it falls in a Harsh or No-Go category, if any score crosses a high-risk line (Comedogenic ≥ 4, Irritation ≥ 4, General Safety ≥ 7), or if our notes flag it as a carcinogen, developmental toxicant, or restricted substance. Other docket ingredients count as mixed evidence — worth watching, not worth panicking over. Some ingredients are evidence for a product: genuinely good ones, including a few that get wrongly feared because of their names.

From there the product gets one of three verdicts. Guilty if anything counts as serious evidence against it. On Probation if there's something on its record but nothing damning. Innocent if no ingredient brings a charge.

We also weigh where an ingredient sits on the label, not just whether it's present. Labeling rules require ingredients above 1% concentration to be listed in descending order, so on a longer ingredient list (8 or more), anything landing in the last quarter is treated as a likely trace amount — under 1% — and serious evidence there is softened to mixed rather than an automatic conviction for the product. It's still on the record, just weighted the way a real formula would weigh it. This is a living docket, and we update it as new research comes in.
