Why take the test?

If you're tracking your cycle, dialing in supplements, and eating clean but still feel off, your body may be reacting to something you haven't thought to check.

This test can help you understand what's going on when you:

  • Feel tired even after 8 hours of sleep
  • Get bloated or puffy, especially before your period
  • Struggle with brain fog or mental fatigue
  • Experience breakouts, mood swings, migraines, or itchy skin
  • React to "healthy" foods or supplements

All from a few strands of hair.

Note: This test is for informational purposes only and is not intended to diagnose, treat, or cure any condition. Always consult with a healthcare provider about persistent symptoms.

It's completely painless. You just have to gently cut 5 - 8 strands of hair, colored or natural, and place them in a small plastic sealable bag.

How long does it take to get my results?

Once your sample reaches our CLIA-certified lab, it's processed within 24 to 48 hours.

You'll receive a secure email with access to your results so you won't be left waiting or guessing.

What happens after I get my results?

You'll receive a clear, color-coded report showing your body's reactivity to foods, additives, and environmental compounds, plus insights on gut health, nutrient status, hormones, enzymes, and more.

We also offer next-step guidance so you know what to eliminate, what to watch, and how to start feeling better.

Can I use this instead of a full lab panel or hormone test?
