How to Choose
Shampoo

What matters, what doesn't, and how to spot the difference.

Five things that matter.

01

Third-Party Testing

Products tested by independent labs you can verify. No lab results? No trust.

02

Label Accuracy

What's on the label should match what's in the product. We find discrepancies in 40% of products we test.

03

Contaminant Screening

Heavy metals, pesticides, and microbes have no place in your products. We test for all of them.

04

Value Per Serving

Price-per-unit tells the real story. A $30 bottle with 30 servings beats a $20 bottle with 10.

05

Manufacturer Transparency

Companies that publish their testing, sourcing, and manufacturing processes have nothing to hide.

What to look for.

Trust signals

  • Published third-party lab results
  • Clear ingredient amounts (no proprietary blends)
  • NSF, USP, or GMP certifications
  • Traceable sourcing information
  • Responsive customer service

Warning signs

  • "Proprietary blend" hiding ingredient amounts
  • Miracle claims or guaranteed results
  • No verifiable testing or certifications
  • Prices that seem too good to be true
  • No company address or contact info

Before you buy.

Five questions to ask about any product.

1Has this product been tested by an independent laboratory?
2Does the label list exact ingredient amounts?
3Can I verify the company's testing claims?
4Are there documented interactions or side effects?
5What do verified purchasers say about actual results?

We do the testing.

Every product we recommend has passed our independent laboratory testing. No brand sponsorships. No free samples.
